We have a BlueAir400 air filter. It does a fantastic job controlling dust and pollen. Highly recommend BlueAir products.
I would recommend this to a friend!

I have relied on your machine as well as the "genuine" filter for over 7+ years. It always amazes me how much your filter traps. I am diligent about changing the filter every 6 months. I'm glad that I set up an automatic subscription! Thanks to your great customer service rep who guided me through the process.

We had waited quite awhile to change the filter and when we did, it made a huge difference. I put it one a subscription and now we won't let it get this bad again.

EXCELLENT Filters ..... Especially for POLLEN. I live in a Forest in Rural North Florida where PINE POLLEN is so Abundant even my roof gets tainted Yellow-Green from late February through March annually. Additionally, during the Summers they filter out all the Grass and Weed Pollens. These 400 Series Filters are GREAT and keep my indoor air POLLEN-Free ..... LOVE 'Em!
