The Defender Filter is 3X better-than-HEPA

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.

Provides three times better-than-HEPA filtration to remove pollutants such as dust, dust mites, and mold spores.

Made with HEGA (High Efficiency Gas Absorption) material, which is highly effective at removing pollutants such as wildfire smoke, tobacco smoke, pet odors and lingering cooking odors.

See what our customers are saying

"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., Shallotte, NC

"We placed the Defender in the bedroom at night and the results have been very impressive. We are breathing and sleeping so much better due to the improved air quality and we get up in the morning feeling refreshed, not tired. It also has significantly reduced our snoring which leads to a much better night's sleep."

– Donald & Randy B.
