I have owned my Defender for over 6 years. I have no control over the contaminants in the air outside, but I do have control of the air quality inside of my home. It gives me peace of mind knowing that I am taking care of my family and their health.


Our family loves our Defender Air Purifier, with allergies and asthma it has help us stay healthier throughout the year.
