"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."
