What was the point of that childish attack?
Everything in my post was 100% fact, I happen to be in the HVAC and air quality business and have air quality testing equipment I leave in homes to test air quality. I have had many people with allergies and skin conditions and immunity issues such as cancer patients who I have helped to make real differences in their home life.
One of my customers used to have headaches almost every day for over 5 years until I helped her clean up her home and today she rarely has headaches. She gives me a big hug every time she sees me.
If you choose to be uninformed in life there is not much I can do for you, but for those who care to learn, there is a lot of information out there, you do not have to take my word for it.
