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.
I would recommend this to a friend!

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.
