Super Impressive Filters

Acquired a 400s from a small business that was shutting down and clearing house. It needed new filters, which came very quickly upon ordering. I am amazed at how quickly the air space in my apartment air became clean. I am grateful to have this device, especially now with the fires in Los Angeles. Our indoor air quality has been prestine, despite all the smoke, duct & Ash floating about outside

Yearly Filter Change

It's amazing how a simple filter change can transform the air in my entire home. A friend who regularly visits, stopped in about a week after the filter change and instantly commented on how fresh my home smelled. He''s a person living with asthma and truly appreciates clean air. That's why I never miss the yearly filter change. It seems expensive, but for a year of fresh, healthy air, that even my guests can appreciate, it a very small price to pay.

It Works

I have allergies and the Airmega filters help keep the air inside my house free of pollen, dust, and any other allergens lurking in the air. I have a small house and it works for the entirety.
