How the Defender works
360° Air Intake
The lower half of the Defender pulls air in from every angle, no matter which way the machine is facing.
VOC & Odor Capture
Air filters through the Enviropure Activated Charcoal Wrap, capturing numerous types of harmful VOCs and unwanted odors from the room.
Air filters through the better-than-HEPA Medi-Filter Cartridge, capturing harmful particles down to 0.1 micron in size.
360° of Purified Air
The Defender circulates clean air back into the room from the top half of the machine.
HEPA is the industry standard (99.97% at 0.3 micron). Our filters have been independently tested to remove 99.99% of particles down to 0.1 micron in size.

This is our second Air purifier only because we have moved to a larger space. We have a family childcare home and I believe this is a big part of how I have not been sick in over 2 years despite children being great germ spreaders!! I would and do recommend!!
I have owned air-cleaner machines for 20 years. I got a serious mold issue from water intrusion after a horrible storm. That's when I began buying "Air-Scrubber" units to run during remediation. They worked well for the process and I have been continuing to use them ever since. But age, and saturation of mold particles, has turned them into infection instead of protection. I began to get sick again and decided to buy a new machine. I am so happy I chose the Defender. I have been running it, full throttle, for a week now throughout my home, and have seen an amazing result. I no longer am feeling sick, or the symptoms of the mold as I had experienced before. This machine has dramatically improved my quality of life. I would recommend it, enthusiastically, to anyone concerned about the quality of the air they breathe at home. I believe I am even sleeping better, and have a renewed outlook on life. Your health is your most important asset, without it you have nothing else. My thanks to FilterQueen . I have had their vacuum for 30 years, still works great today, looking forward to purchasing again in the future.
I just purchased me third defender and now have them in all of our bedrooms. Filtration is the best and they are very dependable. I trust letting them run 24/7 in my home. The price is worth the quality!
