Winix Zero S Air Purifier
Great Product
The sleep mode is silent. It still does the job, but with my dust allergies I prefer to have it on a bit more powerful during the night. So I have it on setting 2 or 3. Setting 4s sound is not noticeable during the day but at night its probably too loud to sleep with on the full power. But even with...

Winix Zero S Air Purifier
Very good all round, good value
This is my favourite of the 3 winix and 1 levoit air purifiers I've owned. The pellet-based carbon filter has lasted longer and worked better at reducing odors than the foam versions, and is washable. The energy efficiency and quietness is great on the lower speeds, while still moving enough air to ...

Winix Zero S Air Purifier
The blue light of joy.
This is a sturdy unit without being unattractive for a living room. It seems to do what it is intended to do. The power rating is 65 Watts, but mostly it should be running at a lower power than this, particularly when it goes into the automatic sleep mode once the light sensor is triggered by darkne...

Very Nice Air Purifier
Disclosure: I am a long time Amazon Prime member, but purchased my 400S from an online retailer that specializes in air treatment equipment because of better pricing and was for sure an authorized dealer (buying from unauthorized dealers usually means no warranty coverage - I have read on other revi...

Ease Of Use

Coway Airmega 400 S Air Purifier
Fresh clean air
I love the AirMega 490s. The air in the house is fresh and clean. The app gives useful insight into how clean our breathing air is inside and out. The 400s is easy to use and the instructions and simple to follow.
