Cleaning my air

This is not my first time ordering from this company and won't be the last time. I did go back to the store bought to try to save money and boy was that a big mistake. So I am back and I will stay a customer till the end

Aegis treated filters, when tested, reduced airborne micro-organisms by up to 86.5% in a single pass! Learn more

Best Decision.

We have been using this filter for many years and are very pleased with the product. My wife has severe allergies and this filter does help tremendously. I would and do recommend this product to many people. Thanks for a fantastic product. Ray K.

Best Filters

Could not live or breathe without these filters. Very seldom use my inhaler at home because of them. You can see the results when you change the filter so you know it is doing what they say it will do. Have tried HEPA filters, charcoal filters, and certain other filters that gave me asthma attacks from the materials they were made from. These are absolutely perfect.
