Air Purifier Zero-S for Allergy sufferers with HEPA Filter (99,999%) Against Allergies, dust, Pollen, pet Hair, Indoor air Quality Indicator and auto Mode, Air Purifier CADR 410m³/h for 100㎡.

This filter informs us our air quality in Dubai is not good, we keep doors and windows closed because of it. Even when fitted in a somewhat contained corner, it still detects particles fairly quickly when the door or window is open. Also when cooking, especially oil frying, this filter indicates the particles. I believe we need 2 more throughout the house to obtain complete 'clean' air. It has a big filter with activated charcoal, but does not really remove odors from cooking or other sources.

I did extensive research to find the most quite, medium sized air purifier and landed on this. However, on 'sleep mode' my specific one makes a tone of noise. I've resorted to running it on the first/second fan speed which I can barley tell its running at night still. I'm giving them the benefit of the doubt that this specific one out of a couple thousand is defected on 'sleep mode'. On the other hand overall I'm very happy with the build of this purifier, It's built to last and the filter system is extremely easy to replace/clean. Also this purifier has the washable activated carbon filter over the disposable one which is a big bonus. To top it off the design is nice and modern but not too modern so this guy should fit classic style homes, modern ones and the in-between. I would recommend this to a friend if I was compensated for the defect, allbeit I haven't chased up amazon that hard yet though.

هدوء الصوت وفلتر قابل للغسل

This is a big beast but it can handle a lot of air. Well made and not overcomplicated to use. Seems to work very well. Very quiet at low setting.

Pros: - not a s loud as many people say even on highest setting - removes the smell of dampness well Cons: - doesn't deal with dust as hoped. Therefore, allergies same as without it - no dehumidification I have no way to measure pollen and never smoke at home so didn't try that either

I did a lot of research before buying this and I'm glad I did, I have severe heyfever and this unit has helped tremendously. The reason I picked this particular purifier is: 1. It has a very effective sensor which means you can leave it on all the time and it will spin up and down automatically to remove any pollutants present as and when required. This means it's quiet and energy efficient and just gets the job done without you even knowing it's there. 2. When you turn your light out at night, it automatically goes into nighttime mode, turning off the majority of it's lights (and dimming the remaining two) whilst slowing the fan down to the point where it is virtually silent (I can't hear it anyway). 3. It has a proper carbon filter not a impregnated sheet like many other machines. 4. It's filters are in the correct sequence to get the most life out of them and it also has an easily removable, cleanable (like a tumble dryer) pre filter to protect the main HEPA and carbon filters. Many competitors omit this reducing filter life. 5. Its just the right size. Big enough to be able to run very quietly during normal operation and clear a room quickly if you had to (for example burnt toast setting off the smoke alarm) and yet not too big to be crazy expensive. The consensus seems to be if you need a more powerfull unit than this you are probably better off buying two units than a bigger single one. 6. It is properly certified and Winix have a good reputation for building solid high performance machines which are great value. The thing that stunned me the most was just how sensitive and quick reacting it is. My partner had been in the garden and walked in the room and it pretty much instantly detected the pollen coming off her clothes and ramped up for a few seconds to clear the air then span down again. If I had to say anything bad about it, it's that it doesn't have a way to run in auto mode without having nighttime detection on. Because it's so hot at the moment we are closing the curtains which is sometimes leading it to prematurely go into night mode.
