Clean Air

We have two dogs who use a dog door so there was always a lot of dust swirling around. The air is so clean now, dust is noticeably less and our air quality is excellent!!
I would recommend this to a friend!

Please bring back the 411

I am sadly disappointed that you no longer offer the 411 air filter; I already have two and wanted another.I ordered the 311and discovered I can’t use it because of the radio/microwave additions. I turned off the WiFi, but something else is causing emissions; perhaps the particle detector?I have a lung condition and am very sensitive to not only smoggy air, but also radio/microwave emissions. I really wish you would bring back the 411; it is a perfect, simple, well functioning device that has literally helped save my life, especially during the wild fires we have here frequently. When you stop providing filters for the 411, I don’t know what I will do. Theirrie Cook

Cat Problems

I have cat allergies and live with a cat. I purchased this filter to help cut down on the pet dander and dust. After a few weeks of use I have noticed an improvement in my allergies and breathing.

Blue Air

I have been using my blue air for about 1 year now. I have 2 cats and it definitely helps with the dander and hair some. The best it works on is when I’m cooking and when there is smoke in the air . I recommend having one in your house. I also have smaller ones for bedrooms. Excellent product ..
