Cat Problems
on April 27, 2026

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.
I would recommend this to a friend!

Please bring back the 411
on April 18, 2026
Posted by: THEIRRIE C.

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

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!!

Love it! Works great! It stays quiet most of the time (except when the wife cooks) and it removes the odor fairly quickly. So far, very happy with it.

New Filter
on March 2, 2026
Posted by: Paul V. K.
from US, United States
Unit did not indicate we needed a new filter but the air indicator light went from green to a white. Our air quality had aways been green. We followed the instructions with no fix until the manual said "call us". So I decided to first order a new filter. The unit is now back to green.No need to call but really!!!
