I'm using two 751 in my 700 sq. ft. home. Amazing almost immediate improvement.

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.

Works for us. Trying the odor filter now. We have the wildfire filters (Southern CA - we are always on fire).

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.
