Very satisfied

I've never owned an air purifier before. I have been quite pleased with with the Alen BreatheSmart FLEX. In my 1462 sq. ft. house, I move it from the open living-kitchen-dining room to our bedroom occasionally. It's usually set on the second lowest speed, but when I move it to another room, I bump it up. On the lowest speed, it's nearly unheard. On the second speed, I can barely hear it, and it's almost indiscernible over the noise of other appliances, namely the fridge. It's been running for about a month now and I'm thinking I may need to bump up the filter subscription from 9 months to 6 months.

First of all, it’s incredibly quiet. You don’t even know it’s on for that reason alone I would buy it again.

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!
