Running strong
We’ve had our Blueair for just over a year now and it has helped a great deal. I very much appreciate how it kicks into high gear after using an aerosol hair product in the adjoining bathroom. Don’t want to imagine all I’d be breathing in without it.

Great system
Outstanding machine. Next to my bed, the air is almost crisp now, the fan very subtle. The app is clear and easy to use. Love it. (Does not hurt that it's not ugly like so many others)

It is working.
I've used this for about a year in my bedroom. I just replaced the filter, which was easy to order, and once received easy to replace. The spring, my worst season, has been mild which I believe is due to the air filter.
