"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."

"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"
