Favorite air purifier I've purchased

[This review was collected as part of a promotion.] I didn't think an air purifier could be so quiet!!! I also love the slim space saving design. Noticeably better air quality after the first hours of use.

5 Starts! Great for dog allergies

Bought two of these. Cleaned up my air so quick. I have a large hairy dog that would trigger my allergies pretty bad at night. Now I wake up and dont even have to blow my nose! Must have for people with asthma/allergies. I've bought cheaper air purifiers before and they dont even come close to how this unit filters!

What a difference!

The Flex has been a game changer for the air quality in the house. The air is fresher and the room simply smells better. The handle and light weight allows for portability which is also something that is quite the convenient feature.
