C1S Countertop Reverse Osmosis System, NSF/ANSI 58 & 372 Certified, 6-Stage, Portable Reverse Osmosis Water Filter, Reduce PFAS, No Installation Required, BPA Free

Wonderful little gadget. I have well water, but pre-treat with a sediment filter and water softener. TDS (total Dissolved solids) were over 250, which ruined the flavor of coffee or tea. The treated water was delicious and refreshing .This device says it reduces TDS to 4, though it rose slightly as the reservoir emptied. The purified water can be dispensed or poured into another container, convenient if a lot is needed at one time, as for a dinner party. It works better than a Brita style filter. Our local wells contain high levels of arsenic, which causes heart disease with chronic exposure. A carbon filter doesn't remove arsenic. Reverse osmosis does the job.

Likes: - compact size - quiet operation - helpful setup interface - easy to use - water tastes great I had a different RO system but apparently they quit selling filters for that model. I decided to go with a better known brand this time. The plastic feels a tad cheap but overall everthing is built well and works fine. I really liked how the machine walks you through the setup process to do it correctly. It also helps to read the well-written user manual. I plan to stay with this machine/brand indefinitely, as long as everything works well.

Great product! We are living in a rental house so this countertop waterdrop machine helps a lot. The local water tds is around 200-300, with Brita and the refrigerator filter, it is still the same, but the waterdrop filter successfully reduced it to under 50! It is very easy to set up and the design is quite concise and modern. I’ve been using it for 6 months and it is still working great. Also the customer service is top notch, they responded to my email in time and solve my issues professionally. Highly recommend it.

First of all, I'm not someone who can't be pleased and cling to negative experiences or product reviews. For the majority of time I'm happy about my Amazon purchases, but lately have been really let down. This product came to my attention because of family member and friend's recommendation about water filer to ensure drinking water safety, as they know my son went through harsh medical treatment last year. I thought I bought it directly from the company who made WaterDrop products but frankly I'm not sure now. The setup is simple, but after numerous tries it just won't finish the flushing process. It stays on 50% forever and when I contacted tech support, they gave out one piece of solution every time, about 24 hours after my email, probably because they're overseas and there's a time difference. I told them this is a defect unit and asked for replacement but they just kept asking me to try fixing this and that. It shouldn't take this much efforts to get a countertop filer to work, it's not a complex piece of machine, and yet it's been sitting here for a week now. Besides this, I also received a glass jar that's broken during transit, a package of spice jars sent to the wrong address, all happened in two months of time, wake up Amazon! This is not the way business was done here before! Furious! Updates about this unit on 2/29: the company sent me a new unit which arrived on 27th, plugged in and it did the same thing: flushing to 50% then just stayed there. Someone called to videotaped the unit and status, offered to call me back later yesterday but never did. I emailed the company again today to complaint. As of now two defective units have taken up my counter space, I have carton boxes all over the floor because they expected me to ship them back if not working. Instead of being a solution to my drinking water quality they have created endless extra work for me! Updates about this purchase on 3/19: about two weeks ago I returned the first unit to Amazon and received the refund. The seller issued me a gift card to make up for my negative experience. They also provided me with free return labels to ship back the replacement unit. I informed them I will update my review to list the facts, but will not change the stars because I believe a product is supposed to be working in the first place to earn good reviews, and the seller is in agreement to that. I do hope that they will fix their production or technical issues to this won't happen to other customers. I am still in the market looking for a high quality countertop water filter to replace the pitcher I have used for many years.

I installed a Waterdrop under sink WD6 RO filtration system over 2 years ago. I love this thing and use it every single day. Not only does it provide clean, pure water for my plants but it's great tasting, crisp, and refreshing. I replaced my 4th filter cartridge a couple weeks ago and it was acting strange. During the instructed 20 minute flush after installation, the TDS display never dropped below 40. That's very strange because when the filter works, the number usually drops down to 2 or even 1. In addition, the water felt slimy to the touch and tasted like soap. I certainly had never experienced that before from this system. Thought to give Waterdrop an email, and they replied within minutes. After some troubleshooting, it was apparent the filter cartridge was flawed. So they had another one sent to me, even though I had purchased this particular one 8 months ago (I tend to purchase a replacement as soon as I install the spare, so that I never run out). Well, I received the new cartridge today and it functions just as expected. I couldn't be more pleased with Waterdrop customer service, and am incredibly impressed that they warranty the parts for this long! I would definitely recommend this company to anyone who is serious about water quality. My experience with Waterdrop has been second to none.

The water tastes good. But there's always water leaking out from the bottom set, making the whole kitchen countertop a mess...

Me costó un poco entender cómo funcionaba (puede que sea porque las instrucciones podrían ser más específicas) pero FUNCIONA! no sé cuál era el TDS de mi agua de la llave , pero el agua que me da el purificador oscila entre 80-20 TDS que es bastante bueno, cuando el agua tiene más TDS o no se alcanza a purificar bien te avisa con una gotita roja , el agua no sabe a agua de filtro , se siente fresca y sin olor ni sabor ... Podría ser que se sintiera un poco más Mineral pero muy ligeramente, no ocupa mucho espacio y ya que le entiendes es mucho más fácil, purifica en 1-3 min unos 250 ml aprox ... Lo que me sucedió es que no había entendido que cuando queda poca agua en el tanque rellenable la tienes que desechar , yo simplemente rellenaba el tanque , entonces en automático el TDS de me elevaba bastante ... Van 10 días y nadie de mi familia se ha enfermado o quejado , me olvide de cargar garrafones, estaba preocupada porque no conocía el nivel de TDS y normalmente en la región dónde vivo en México el agua es muy pesada , pero me resultó 100% bien , purifica el agua 💧 perfecto.

Great water filtration system for home. Easy to use and like the preset volume setting. Water tastes good. Hope it will last in time

Really love this filter. This is well worth the $350-400 range. Tastes great, filters in a reasonable time and reliable because of simplicity. Its not fancy and thats exactly what you want in a filter. Takes a single all-in-one filter that should last a year. My only gripe is the rather small capacity for two people and the need to empty it out and refill again. I’d love the ability to get a larger tank but I’m not complaining at this price point.

I bought this product. After installing on counter top After plugging in to a power source there was no indication on screen with lights. I called the technical support as indicated on brochure and website - response received that the agents are busy and to leave a voicemail. I received a call back and the agent was very helpful in creating a case for me. I was able to use the machine. The water drop filter is amazing. Very clear and tasty water. I even tried boiling the filtered water in an electric kettle several times and found no sediments collected. I recommend this water drop filter. It’s worth using this product

Very nice machine, the water has absolutly no taste anymore.
