"My son suffers from severe allergies from trees, grasses and weeds, and it gets tracked in and trapped in the house. But with the Defenders, it makes his life indoors tolerable. I don't have to dust as frequently, leaving me time for other things. I can't remember the last time anyone in the family was truly sick. Best investment I ever made for my family's health!"
Geraldine T.
Washington, USA
"I personally use the Defender in my home as well as in my medical office. Since using the Defender at home, I have noticed a big difference in the air quality in my house. Also, I do suffer from seasonal allergies, and I have noticed since using the Defender, I have not been congested and I am able to sleep through the night without being congested. Patients have also commented on the air quality in my office since the installation of the Defender. I would highly recommend the Defender for allergy sufferers as well as people with breathing disorders such as asthma and COPD."
John B.

"With the amount of patient traffic and doctors we have in our clinic, I’ve gone ahead and put the Defender in each of our three office locations to try and mitigate the risk associated with aerosolized infections"

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.
Particle Capture
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.
