"I have the Defender air purifier and love it. Very easy to maintain and it does an excellent job. I am a heart patient and have COPD. Living the the California Central Valley, air quality here is very bad, especially with all the wildfires this season. The Defender has really helped a lot, and I would be lost without it." - Joe A.

You cannot control the unhealthy, smoky outdoor air, but you can control the air indoors.

"Designate a room that can be closed off from outside air. Close all doors and windows. Set up a portable air cleaner to keep indoor pollution levels low when smoky conditions exist."  

- Department of Homeland Security

Customer Reviews

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.


I have a wood burning stove. Occasionally, smoke escapes from the stove when I feed the fire. The Defender quickly and efficiently removes the smoke from the air.



I am very happy with my purchase. I noticed immediate results. I put one of the Defenders in my bedroom and I could feel the difference. The air is so much cleaner that it makes it easier to breathe and get a better nights sleep.
