(O-888) - Deodorizer for Medium to Large Areas

I will put in the full product names again further down, since Amazon seems to mix and match product reviews. The unit I'm reviewing here is the Enerzen Commercial Ozone Generator 6,000mg. I have previously had an OION Technologies B-1000, which is okay and suitable for continuous operation. The Enerzen unit is NOT for continuous use - it makes way too much ozone to use it that way. Read on ... For $80, this ozone generator is a great buy! It puts out enough ozone to knock back the musty and pet-litter odors in our entire basement in just a few hours. Details follow. We have multiple cats, and one upstairs bathroom was their litter-box room, along with several boxes in the basement. When we decided to move the upstairs litter box elsewhere, I cleaned the room (including wet-mopping the floor), but the cat-pee spell persisted. I tried a single-room "air purifier" ion generator (OION Technologies B-1000) and while it did help, it was not enough. So I bought this unit (Enerzen Commercial Ozone Generator 6,000mg) and let it run for 30 minutes. Major improvement. Just to be thorough, and because I'm a firm believer in overkill, I then ran it overnight. Odor is GONE. The basement experience was similar. In addition to pet odors, we have had water get into our basement a couple of times - we're not talking about sewage, here, just outside water getting in through the foundation during heavy rain, and a one-time plumbing problem. I finally got the indoor-outdoor carpet fully dried, but there was a musty, mildewy, perhaps moldy odor. Ick. I rigged up a pretty good air-circulation setup, which helped, but the odor just persisted. Enter the ozone generator. I ran it for a couple of hours, being sure to keep the basement closed off for an EXTRA couple hours to let the ozone degrade back into harmless oxygen, and the odor was almost gone. So I ran it again, this time running for six hours overnight, with a few hours afterward to let the ozone dissipate. The musty smell is GONE. Has not come back. We now have our pet litter boxes down there, and if I don't keep up with them, the litter smell (kitty pee and poo) gets pretty nasty. I then 1) chide myself for not keeping up, 2) clean the litter boxes, and 3) run the ozone generator for a couple hours and the basement is PERFECTLY LIVABLE!! I highly recommend this product. Enerzen Commercial Ozone Generator 6,000mg. A caution - ozone is bad for people, pets and plants. Do NOT run this unit without closing the space off from people and pets, and be sure to take your plants out. When I run this in the basement, I shut off the central air while it's running and for a couple hours thereafter, so we don't get the ozone throughout the house. The time or two that I have forgotten to shut the AC down, we got a pretty strong after-the-thunderstorm smell throughout the house, which reminded me. No ill effects from that, but it was a pretty brief exposure. Also, I'm told that ozone is bad for, well, pretty much anything that breathes. It does seem that we don't have nearly the population of creepy crawlies in the basement anymore. Perhaps spiders, centipedes and other bugs do not tolerate a heavy dose of ozone for hours ... ? ----- Edit added in 2026 I have now purchased THREE of these (since 2020). I have loaned them out to friends & co-workers to help with musty basements and pet smells, and they all report that these ozone generators are VERY effective and much appreciated. I had occasion to look in through the grillwork at one point, and I could see that the violet light on the ozone-generating element was NOT covering the element. I read that it was possible to REPLACE the element, but I wanted to try CLEANING it first, so I took the cover off (a few sheet-metal screws), and was able to disassemble the inside enough to get the element loose in my hand. It was pretty easy to clean, with a bit of spray cleaner, a little toothbrush action and paper towels. Reassembly did not go as well - I cracked part of the mount . . . but it didn't seem to matter. I got it back together enough to hold the element securely in the air-stream from the fan, and when I fired it up, the violet glow covered the entire element again. So, easy to maintain! Again, these ozone generators are terrific! A great buy!

A product that lives up to its claims. About 2 years ago, I moved into a townhome I had been renting out for several years. I found that the tenants 2 college age boys had moved in (against lease terms) and were chronic smokers (way against lease terms). Luckily, they had locked themselves into the master bedroom and bathroom but did a number on the place above and beyond the deposit over the course of 3 years. The smell was horrific, and a month after painting and replacing carpet, the stench was still terrible. I got a quote from ServPro for about $2700, which I couldn’t afford at the time. I noticed in the quote that they’d be using ozone generators. I was already familiar with the technology behind them, and had used similar technology years before. Unfortunately, they’re illegal in CA as of 2017, because CA knows what’s best for us. Apparently, people can’t read the warnings and would sit in a room with the things running. Or more likely, legislators have invested stock in ServPro and other smoke damage experts who are undoubtedly quite happy about this law. So, I bought the machine, had it shipped to a friend in TX who then forwarded it to me. In a 20x15x10 room, I ran the machine for about 12-14 hours, and then again in the bathroom (the worst) for another 12. It was amazing. It smelled springtime fresh and the odors never came back. The light fixtures were still yellow, but that was an easy fix! Since then, I have lent the machine to realtor friends for pet odors, smokers and general mildew smell in laundry rooms and garages. Let me tell you, cat urine is a category all by itself. In all cases, the machine did its job. Recently, I moved into another vacated property and ran the machine in the garage for a few hours. I had already bug-bombed the place a few weeks previously. There were dead spiders everywhere, and the wet, mildewy smell was gone (apparently the tenants had an aversion to closing windows and doors during rainstorms). Pros: - Oxidizes all organic matter (smoke, mildew, pet dander, pet urine, bugs, mice, etc.) - Compact size - Powerful - Inexpensive - Harmless to foodstuffs etc. Cons: - No filter - No replaceable grid - Only oxidizes organic compounds/matter not chemical caused odors - Illegal in CA and possibly other states - Must vacate area and air out before coming back - Can possibly begin to break down plastics, rubber, foam etc. with overuse If you’ve got teens active in sports, you don’t have to worry about buying all kinds of odor masking laundry garbage for their room or clothes. Hang their stuff in a garage, sealed closet or laundry room and turn on. Stick it in Jr’s room while he’s at practice. Cat box stinking up the place? Puppy make a mess on the carpet? Clean it then run this baby for a couple of hours. Inherit Uncle Bob’s Plymouth Roadrunner, but he smoked cigars? A lot?!? Stick this box in the car and run for a few hours. Problem solved. Got spiders in the garage? Ants? This thing will make short work of icky bugs. As of 8/7/21, Shawn Wood (on Youtube) who has a show called Moustrap Monday will be testing to see if these either kill mice/rats, or more likely, are such an irritant that it drives them away. I’ll update once he tests this out. So far, he’s eliminated a yellow jacket nest, which is impressive. If there’s a downside (besides potential overuse breaking down plastics) it’s that you need to allot time necessary to use it. That also includes time to air out a room. So you’ll need to plan ahead. Make sure the kids aren’t going to be coming in, and that there’s time to air out (with fan assistance if needed) so people and pets will be safe. Plus, it smells *so* good afterwards! Like after a rainshower/thunderstorm. Are there better machines as far as longevity and design? It appears some are designed for longer use with replaceable parts. They’re also more costly. When I bought this, I wasn’t sure it would work. However, I’d buy the exact same machine again. I’ve used it many times, lent it out many times, and it’s not skipped a beat. Unless I’d need to do a very large space and was pressed for time, I’m not sure what the advantages for a larger machine would be. I’m very happy, and think you will be as well if any of this looks compelling to you. So, recommended? Without hesitation, 5 stars.

Facts behind purchase: 3600 sf, 5 bedroom home on two levels, basement and main floor. Problem: No-see-um gnat infestation inside my home. Results: This is designed to remediate odor. There are two of us in this house, soon to be seven had these blonde colored, less than a MM long, attacking us at night or early morning. If we got five hours sleep we felt lucky, most time two and three hours of sleep. What we tried: Bug spray- name the type and brand, we tried it. Peppermint, and any one of a hundred scents; cider vinegar and soap; diatomaceous earth, borax, Windex, dryer sheets, room deodorizers (choose flavor we used it). None of the above mentioned worked. I burned my face with oil, but they attacked anyway. These gnats crawled in our eyes, nose and mouth, mostly our eyes to the point cold packs were needed for swelling. Our options were 1. burn down our house, 2. sell and let someone else deal with this or use malathion based spray inside. 3. Buy a nuclear bomb. The gnats are flying microbes you can't see but feel them under eyelids, crawling in your nose or other facial hole. I thought we might have an A/C mold, so after cleaning it, still had a problem. These are invisible, light brown gnats; once they infest a home they7 don't die. We vacuumed daily; shampooed carpet, washed walls, doors, hanging photos; washed bed, sheets, comforter, everything. Changed towels daily, closed bathroom drains and sprayed Windex on faucets (they live in the faucets, i think). Mopped the floor daily; had a pest control company spray. Nothing we did made a difference. Then I bought this ozone generator. Here's what happened, the living gnats disappeared. It didn't kill any gnat eggs but as they hatch this OG eliminates them. First room, a guest bedroom for 20 minutes, let the air settle for an hour or two, ventilated the room. Second room, our bedroom 30 minutes, Basement 45 minutes, main room 40 minutes, repeat rooms. We've had it a week. We still have gnats, but the population is diminishing every day. Ozone depletes O2 and they cannot survive. The Ions attract them and they disappear after a few minutes use. Caution: Don't stay in the room where this is in use. This unit is powerful and does the job. I know it's not designed for pest control but I read a posting about using a O3 generator might work. Having nothing to lose, I use this every hour of the day in different rooms. It's working. Gnats are going away though they try to stay alive, they don't. I've used this in one room three times for 30 minutes. It works and we are getting sleep, feeling better after a week. We have a few weeks ahead to eliminate these pests, but this generator is a life saver for us. Results might vary if this is your problem, for us it's doing the job and worth the money. If I could afford it I'd add two more, but we'll make do with this one. Heed the caution on the unit, stay out of the room until it's finished, wait an hour otherwise you might feel lung irritation. Ventilate the room. To avoid infesting our house again using AC opening the vents not windows. Highly recommended for a fresh room and cleaning the air.

This review is ONLY for the "Enerzen Ozone Generator 60,000mg Industrial O3 Air Purifier Deodorizer (60,000mg - Black)", NOT for any of the other products that Amazon has grouped under their same product listing. BTW, the manufacturer's model number for this is O-777, which Amazon's listing does not mention. I bought this product to de-odorize some vintage equipment that I bought, and found that it reeked of tobacco smoke/ashes. Exposure to ozone will usually removes such odors from inanimate objects. It is important to mention that this product generates ozone (O3), which while being useful for many things is ALSO a toxic gas, harmful to humans in greater concentrations and/or for longer periods, and is likely to outright kill small animals (many pets) and also plants. It should NOT be used in any enclosed space that also contains any kind of living thing. Happily, ozone will naturally decompose into other safe gas after a fairly short period of time. Regarding THIS product, it is very simple. It is a metal box containing a small fan, a power supply, an ozone-generating assembly, and a timer. It comes with a power cord having a typical 3-prong 120V North American AC-power plug at one end, and an IEC style plug at the other end (same kind of connector used on most consumer electronics & computers for their AC power cords). On the front panel is a knob for the timer and a red indicator lamp that illuminates when ozone is being generated. The fan also runs any time that ozone is being generated, sucking air in through slots on the back and blowing ozone-laden air out through slots on the front. The time is much like an "egg timer", and operates using a spring-powered mechanism. Turning the knob clockwise from the OFF position will start the timer running, and will also energize the fan and the ozone generating element. The timer setting range from essentially zero time, up to 180 minutes (3 hours). For longer periods, the user can instead turn the knob counter-clockwise from OFF to the HOLD position, where it will stay until turned back to the OFF position. The red lamp shows when the device is operating. When turned on using the knob as described above, the pungent odor of ozone (not all that dissimilar from that of chlorine) can be easily smelled within a couple seconds. To de-odorize a room, close all doors and windows, remove any plants and banish all children and pets to elsewhere. Set this product centrally inside the room, turn the knob to the desired time duration, and leave. The product comes with a sort of "do not disturb" plastic card with a doorknob hook, such as hotels and motels often have, except the wording says "do not enter". Within half an hour or so after the unit turns itself off (when the timer elapses), the instructions say that the ozone should have mostly decomposed naturally to the relatively safe O2 gas, and it should be OK to re-enter the room and either open some windows for a while, or run a fan or other air-circulating device to 'air-out' the room before bringing back plants, people and critters. To de-odorize objects, they and this product can be shut up together inside a box, etc. Of this product is placed inside a car with its doors closed, it can freshen the air inside (it still needs to be aired out afterwards). A large cardboard box might be used, etc. A shed or detached garage might also be used. This product is made with an all-steel case, good quality carrying handle and power cord. Internally, it appears to be well-made. The instructions note that with light and occasional use, the ozone generating device inside might be expected to last a few thousand hours, but with heavy and/or frequent use, only perhaps 500 hours might pass before the device can no longer produce ozone. The Ozone generating device can be easily unplugged for replacement, and Amazon sells the replacement devices in packs of two. Since who knows how long those might remain available, it might be prudent to buy a pack at the same time as purchasing the product itself.

Original review Dec 2021: Added update July 2025 below. My house has always had an odd smell since I bought it 12 years ago (2008). My sister could smell it on my clothes even when I went over to her house. Perhaps a bit of mildew as I've noticed dusting on wooden surfaces, windows, doors, and cabinets. I've cleaned them, and even put a fresh layer of polyurethane over all my wood surfaces (which helped briefly). I don't see dusting anymore, but the smell persisted. With the pandemic, lots of talk about treating air with UVC. That triggered memories that UVC lights are commonly used to disinfect operating rooms at work. So I gave it a go with some lights I picked up from Amazon. Well, success! But hard one as I had to do each room like 6 times, moving the light each time. From reading reviews of UVC lights, I came across the idea of ozone generators. They work much more globally that lights, filling spaces the lights cannot touch effectively. Both types of units are dangerous and have to be used with caution. I've been burned by UVC lights in the operating room with tidbits of exposed skin. And ozone is tremendously harmful to life, not just microbes. In particular for humans, toxic for lungs. So you need remove plants, pets and people from your home. I bought this unit in cold weather so opening windows was out (I had storm windows on anyway). With a bit more research I found that the ozone breaks down over time. Depending on how much you generate determines how long before it is safe to reoccupy. However that is hard, and I found recommendations that 2 hours after using generator is a very conservative safety margin (many sites and manufacturers suggest one hour is enough). Thus it was easy to simply use for the maximum time either whole house or per room and add 2 hours and not bother with airing out the rooms or house. Easy to use. Love the mechanical timer, a simple old fashioned dial just like a kitchen timer. No delay before starting so be prepared to leave the house immediately. There is a distinctive smell after using that in my experience lasts about one day at most. Not an unpleasant smell at all, smells clean. Not unrelated to positive ion generators I think. Good value, and I read tons of positive reviews here. As a huge bonus, it kill spiders!!! Other insects as well presumably. July 24, 2025 Three and a half year update Lots to share here. I have used this roughly 5 hours a week on average, or about 800 hours total. Typically 3 hours on the timer, and then I delay returning home for another two hours to let the ozone deactivate. After 2 years of highly successful use, after five hours away, I came home to a smoky home - light enough that I had to look twice. Later it was highly obvious on return home. I attempted to contact Enerzen about safety, both fire hazard and lung safety but they never replied. I continued to use another year and a half, using my internet controlled Nest thermostat to run the furnace fan for two hours so I at least filter whatever the smoke is. Now three and a half years later, it appears my usual once a week house treatment is no longer as effective. So I figured that I should probably replace the ceramic ozone plate. Received that today and it doesn't fit (per several other reviews here). See attached picture. Looked easy enough to modify, just use a Dremel to cut out a divot in the replacement plastic plate. Wrong! Made from metal, a no go with a Dremel. So I did some more disassembly to modify the bump on the socket where the plate plugs into. Also looks like plastic, but simply coated steel that appears to be hardened. I went through a new cutting disc on my Dremel that is usually more than sufficient for cutting through a bolt the same size, and only cut about 1/16" at most. I then tried a bench mounted belt sander - did nothing. A hacksaw refused to cut as well. The "manual" that came with the unit was terrible, picture and description of how to replace plate was totally inadequate, not even a model number (but neither does the main Amazon listing, nor does the Enerzen store). It turns out this is the 0-777 model which the Nispira replacement plate specifically says it doesn't fit. But it is the only one sold by Amazon whose picture is a match the model I purchased. It is not sold by Enerzen or any other vendor online. So I guess I now have a pile of scrap metal. One other thing I didn't catch is that Nispira said their plate has an output of 3,500 mg/hr of ozone. Enerzen rates my model 0-777 at 10,000 mg/hr. It also rates the 0-555 model which the Nispira replacement is supposed to fit at the same 10,000 mg/hr. Something fishy going on here. Nispira also rates the replacement plate with a 5,000 hour life. That is also a disconnect with my original plate not making it more than 500 hours before smoke started forming. By the ways, some of the plastic (not all) inside the unit has deteriorated from ozone exposure. Possibly that is where the smoke came from. I'm not sure how to proceed. I guess I could purchase the far more expensive 0-555 unit ($120 versus $75 0-777 unit both with same ozone rating), and take it apart and see if my replacement Nispira plate fits it. Of course, that seems iffy since the Nispira plate is not rated for the same output. Update August 4, 2025 I didn't explain the attached photo. The plate on the right is the original plate on my 0-777. I managed to snag a new 0-555 on eBay for an amazing $45 delivered! Without disassembling it I could see through the grill that it uses the same ozone generating plate as my 0-777. If you need to replace the plate on either model, make sure it looks like the plate on the right. I did manage to get the right plate for my 0-777 from Oion (the manufacturer of Enerzen products) standalone web site. $12. It was listed in the Amazon Enerzen store but as out of stock. And even Oion's site, it said there was only one left. And boy, did that new plate make a difference. Lots more ozone production, and no smoke/fog produced. No need to run my furnace to filter the smoke before I returned home. House smelled far better than before I replaced it (similar to using it when new). But it looks like you can only count on 500 good hours of service before the plate should be replaced. Probably most people who buy this just have a one time need for it, like in a new apartment or house, so this issue may not be reflected in very many reviews here and may not be important to you. I depend on this thing for odor control at least twice a month, but after two years of use, I was doing it weekly. Think I'll be back to two week intervals. If you replace the plate on your unit, be aware that you need some thermal paste to install it to transmit heat better to the heat sink. I did note that when I took off my original plate, the thermal paste coverage was not optimal. That could be a cause of early failure on my unit - 500 hours versus a claimed 5,000 hours. I used it for the maximum 180 minutes each time, so that would be worst case for heat production. I took care when replacing the plate to have maximum coverage on the thermal paste I applied. And I now have a second unit (the 0-555 from eBay) as backup. In doing some research in trying to replace my plate, I heard about recommendations on a site selling commercial ozone generators ($500 up to a couple thousand) talking about "shock" treatments for odors - which means hitting rooms with massive amount of ozone. Sometime this year, I will try both units at the same time to see if the treatment lasts longer. The site was really talking about hard to get rid of odors, not so much how long a treatment might last, but worth a shot! Congrats on making it this far in this review! Really long but a lot of information that hopefully proves useful to those who read this far.

To start with, please research this item before using it. This can be *extremely* dangerous to you and your family's/pet's health if you don't know what you're doing. With that said, we love this thing and it has not given us any issues or problems in the nearly 2 years we have had it. If you are careful and follow proper safety precautions this can do so many good things. If your car smells like rotten milk, if you bought a used car that reeks of cigarette smoke, if you have water damage and/or musty mildew or mold on items, this can help. Ozone has the ability to kill the bacteria, and other living organisms that are responsible for those horrific smells that come from mold, mildew, smoke, rotten milk, etc...that said, being that ozone kills bacteria and organisms, it will also kill humans and pets if they are exposed to ozone, so do your homework on how to be safe before using this item! Don't take that warning lightly. We have used this item several times to remove mold from stuff from our old house, and to clear up mystery smells in cars we have bought. Basically you just set the product up in a space where humans and pets will not inhabit, seal all doorway cracks that may lead back to the house or living areas and crack windows in the room where the unit is. You don't need much to fill small spaces, so unless you have a mansion or are trying to fix a whole house, you shouldn't need more than about 15 minutes of run time following by a few hours of time to let the ozone do it's thing. Ozone is heavier than air, so it can seep through the bottom of doorways and down stairs or through vents, so if you are using this indoors, be sure to block the bottom of doors or low vents with towels and keep any family members or pets away from the room you're doing treatment in. I know it may sound like I'm over emphasizing the danger, but seriously, it's no joke. This has helped us in recovering family keepsakes and memories that we thought we would have to throw away when we found out there were mold problems in our last home. We often set up the ozone machine in a small tub with items that need to have mold killed off and run it for just a few minutes and let it sit in the ozone for 12 hours or so, then repeat as needed. Once we finish the treatment, we open all doors and windows in the room and several in the house to let the ozone dissipate. Do not go in close proximity until the "petrichor" smell is gone. That smell of fresh rain(or petrichor) is the smell of ozone, so if you smell that, step away, that's bad for you and can damage and irritate the tissue in your lungs. We used it once to treat a car and we probably ran it longer than we needed to. We sealed all doors and windows, put a box fan in the car to circulate the air and ran the ozone generator for about 15 minutes and let it sit with the fan blowing and car closed for the next 24 hours. The next day we started the car, ran the air on recirculate for a few minutes, closed up the car and did another 15 minutes on the ozone generator then let it sit another 24 hours with the box fan blowing. After we finished the second treatment with it we opened all the doors in the car, turned the air on to bring air from outside and let the air run with the car on for about 30 minutes with everything in the car open. After we turned off the car we left the car sit completely open for around 4 hours. The next day the smell was still there and was still pretty strong. It took about a week of leaving the car open a couple hours a day before the ozone smell was gone, but it did fix the bad odor issues. So be careful not to overdo it, a little bit goes a long way. Keep in mind that you still want to find the source of the smell and remove it before treating if at all possible. Bottom line, this has been a lifesaver in recovering sentimental items that can't be replaced because of the memories. It has been well worth the price, even for the few times we have used it, because of the memories it has saved. Absolutely worth the price...but again, please be safe and cautious.

TL;DR. It works to de-stink funky smelling rooms. If it doesn't; Amazon or vendor will repair or replace parts. I recommend it! 28 Nov 16 update: After emailing a picture of the broken generator plate to the return email, a new plate was shipped out for free. It took me a while to figure out I could just bend the top clip up to get the plate underneath it so it fully contacts the heat sink. I'm guessing issues with that may have been what caused the initial issue. I did buy & use more thermal paste to ensure good heat contact to heat sink. Now that I've seen in run with the new plate, it's clear my original plate was broken on arrival. What's odd/ cool is that even with about 1/10 the ozone it now puts out (gobs!!) it totally removed the "wet basement funk" smell from my garage. Now that it's running full speed, the basement is smelling like any ol' room. Even after fixing the sewage block caused by someone (hrm plumber cough) dropping a cut out of the 2by down the drain while installing the sewer vent. I also took it to a hotel room when my parents visited and wound up in the last available room in 30 miles under $150. It was stinky so we ran the generator for 45 minutes while we had dinner out (90 min). My asthmatic mom could breathe better afterward. Time delay between this update and previous update was my delay, not vendor delay. After they got my pictures my part came in 2 days. 22AUG16 update: Took box back down to basement from attic. Carried it gently, didn't bang it around. When I turned it on, product produced small yellow sparks and snapping noise intermittently. Didn't sound normal. Didn't look right. Turned off & lifted box to look in and a 1.5"x0.375" piece of the ceramic plate fell out. Pic is of a part of that bc contractor stepped on shard. Based on 20 years of troubleshooting microelectronic failure mechanisms and a degree in materials engineering, my theory is that the plate got a minor crack in shipping which propagated under stress when I turned it on and came off when I moved it. I assume that replacing the (consumable) plate will be enough to get it back in action, but need to contact seller to get replace it. If that goes smoothly, I'll re-increase my star rating. Because my basement no longer smells like a flood basin but could use more work. 14AUG16 original: Got this a few days ago. Leaving it on overnight (at 2 hr Max) in the house I'm rehabbing. By 2nd day, most of the dank, mildewy smell was gone from my basement garage - even with the sump full of water. Yesterday I ran it in the attic, which has had all the putrid insulation removed but still contains a funk in the air making it unpleasant to breathe there. Today, it was much easier to breathe the air up there. This is great because it makes working easier and because I'm turning it into a loft. As others have mentioned, the power cord is short. When I read that, I thought, "Use an extension cord, dummy." But now I see what they mean. A couple more feet and positioning would be much easier - it almost reached 2 of the 3 places I wanted to put it so far but not quite. If possible, I'd rather not use a string of extensions to plug in something generating electrical sparks. A few folks mentioned that this will kill rubber, which makes sense. But I put it on the rubber stair treads to my basement (at the edge, aimed off) and 3 hours did not do anything noticable to said rubber. Yet. Probably because there was easier funk to attack, or maybe it's sturdier vulcanized rubber. I turn it on at the source to make sure it turns on without issue, then vacate for run time plus 2 hours or overnight. Breathing at my house has become easier, much to my relief, because I'm allergic to living things. Yeah, yeah, buying a house with dank basement mildew wasn't a genius plan, but it was all remediatable. I just can't live there yet. This is helping speed that up with the "shock treatments" significantly improving air quality. Box is small but mighty. Would have increased a star with a longer cord & a "hold on" option available, although I could see that going horribly wrong, so maybe I'm just a mean rater.

I'm dubbing this the smell destroyer. Think of it as an air bleacher. I have owned 20+ rental units over the last 10 years, and I am at a never ending battle of destroying the lingering smells of previous tenants. After all, nobody wants to rent a unit out if the first thing they notice walking in the door is a funky smell. After owing this bad boy for about a month, it saved me three times now. Paying for its self three times over. I wish I had found this unit years ago. It's almost like a contractors secret. Epic uses: - I've used this for a living room that had a nasty cigarette smoke smell caused by tenants smoking on the patio, but apparently never closing the sliding glass door (what they've promised me) I used to have to pay my carpet cleaner $75 extra for Deodorizers out of the carpet for all these years that didn't always work. Only to battle painting the unit since the tobacco tar sticks to the walls. After two maxed timer treatments, the smell is gone.I have been in units cleaning the walls/carpeting would be required, but this is such a cheap option I am including an 'ozone treatment cycle' with every issue. - This will treat minor animal smells in an avg sized bedroom. Professional carpet cleaning will still leave a room smelling like wet dog. This won't 100% eliminate the smell, but a good 75% for the stuff that is deep in carpet pads. A VERY cheap option before spending $300-400 per bedroom on carpet and pad replacement. - I have yet to test it on, but can't wait to try it out on a unit that has had a cockroach infestation. I believe this will eliminate it. They leave a smell that you will never forget once experiencing, that has lingered around after painting, cleaning, and carpeting a unit. - Eliminating the old person/moth balls, or baby smell. I had purchased new rentals that had these smells. Both eliminated. Food for thought: -I tried this on a bathroom that had a bad mold smell from under the sink. After two 2hr treatments, the smell remained. We discovered we needed to replace the bottom of the cabinet board and bleach spray/scrub out quite a bit of nasty mold. - A contractor I use has an industrial unit he charges $400 a treatment. If I ever have a minor kitchen fire or closed flue fireplace fire start that smoke (smells) out a unit, I might consider buying a stronger unit. I've read that a 7k unit will eliminate twice as much as a 3.5k unit, regardless of how many times 3.5k treatments are used. - - The contractor also said ozone 'eats up' rubber. Meaning you must remove all speakers from the room, cover up refrigerator rubber seals, and some window seals. I intend to test this theory in due time with old rubber things. - I can smell the 'bleached air' ozone even 3hours after use in a small bedroom. I'll air out the room from the window before going back in. If you hold your breath and flash a flashlight in the room you can see the flashlight light beam while ozone is present. - I found a version that has a UV light that also 'kills mold', if anything happens to this unit, or if I expand my smell killing arsenal, I will definitely spend the extra money on a unit with that feature. Maybe 1of 10 uses this has would theoretically benefit from this, so its not something most general users should be hung up on. - I had to tape up a painters cheap plastic tarp to separate a 900sqft apartment up into two parts to eliminate the smoke smell. a $5 materials cost is a very minimal in my opinion. Things it won't be very effective on: - eliminating a pet odor with couches and mattresses still in the room, it wont penetrate that deep. It may not clear pet smells after they sleep on the carpet for prolonged periods. - Eliminating heavy cigarette smell off walls (test by wetting a paper towel and scrubbing a wall, if its brown...cleaning comes first) - A nasty bathroom. Clean it first. This is a final aid type product that will thrive after the source of the odor is eliminated. - After my grandma bakes in my kitchen. You would be a cruel person to attempt such a task. 6 months later update: - The two hour timer has to go. Anybody ever swap it out for a 12hour setup? I put this unit in a 20ftx20ft bedroom that had a dog sleeping on the carpet for probably a year. Carpet cleaning evolved the smell into wet dog smell. 3 trips later after every 2hours is progressing smell elimination, but its sure is annoying needing to go back all the time. (update....ended up replacing carpet) - The house also had a nasty roach infestation. I found a few adults still running around in the bedroom after 6hours of treatment. shucks. those things really can live through anything. One year after purchase: Still using it on odd odors that are hit/miss.(maybe 50 2hr cycles) I purchased a similar unit that promised a higher output. It had 3 slide in ozone plates, a bigger fan, and the unit that is 2x the size and weight. I am not convinced that the 3 plates put more energy out as this single 'mini' plate. The new unit puts out the same noise, but you cant see the plasma looking electricity (like in those storm balls toys that attract lightening to you finger upon touching) flowing through the plate. I couldn't find much on the web about it, but this unit sure as heck has a stronger ozone smell than the other unit i purchased.

We recently moved into a flat that had clearly been heavily smoked in. The smell of smoke just wouldn't shift - we had the windows open every day, but closed them every night. Each morning, we wake up to the smell of stale cigarette smoke all through the flat. I'd read online about ways to get rid of cigarette odours, and everything kept coming back to Ozone treatment. Finally, I decided enough was enough and bought this machine - and WOW. I am genuinely impressed. We ran it for various times in different rooms - in the lounge and the hallway where the smell was strongest we did a couple of treatments at different times (30 mins/45 mins, even up to 1.5 hrs). The ozone smell is quite distinctive and harsh on the throat so make sure you don't breathe it before you can open all windows and air it out fully. It has made such a huge difference to the flat - it was horrible to smell cigarettes every single day in every room. I really recommend this machine.

Es un muy buen producto lo recomiendo, es lo que esperaba además llegó antes de lo esperado.

I have been trying to get rid of old cigarette smell which lingers in our house from a previous owner. I was facing having to wash all the walls with sugar soap then seal them and repaint all the walls and ceilings, plus clean all the woodwork. Would have cost a lot of money and taken a lot of time, which is something I don't have much of. I bought this after reading some reviews, took it upstairs and ran it for about 20 mins. I then went shopping to let it do its work, then came back and opened all the windows for about an hour. The smell was completely gone! Not just the tobacco smell though, any other smells were gone too. It smelled slightly like a swimming pool that had just been cleaned. Some notes: as 03 is heavier than air, some of it went under the door (which was closed) and then down the hall and down the stairs, so I could smell it downstairs too. Not a problem, it disinfected/deodorised the stairs too. The next day some of the original smell is only very faintly detectable. But another dose or two should do the trick. In sum, this has saved me a lot of time and money, and I'm really pleased I bought it.

Guys, this is worth the buy, we spend a lot of money on pesticides and other bug sprays but I use this once in my room where I had small bugs that came in and now my room is bug free. This goes into all nooks and crannies. we are best control cannot penetrate since this is gas. it has also removed certain orders in the room that were prevailing for quite some time and I didn’t know where this is coming from.

La macchina è solida, potente come descritto, facile da utilizzare. È sufficiente collegare l’alimentazione e ruotare il timer per il tempo sufficiente a coprire la zona da sanificate, come da indicazioni. Questo ozonatore ha sostituito un precedente modello di altro produttore, che aveva problemi di funzionamento e, rispetto al precedente mi pare vada molto meglio. Unici due nei: 1) il timer non permette di utilizzare tempi brevi, parte da circa 30 minuti minimo; 2) IL CAVO DI ALIMENTAZIONE HA LA SPINA INGLESE UK, QUINDI PER UTILIZZARLO È NECESSARIO AVERE UN ADATTATORE, OPPURE UN ANALOGO CAVO CON PRESA ITALIANA O SHUKO. Per questo secondo lato negativo ho messo solo 3 stelle, un prodotto venduto in Italia non può essere corredato di spina UK! Per il resto, finora, ha un funzionamento egregio ed è utilissimo per sanificare gli ambienti da batteri (molto importante in questo periodo) e muffe, oltre a deodorare,
