I agree it is a HUGE DEAL! I lived it and it was horrible!! This is where all this mold testing and clean environment is so frustrating! I am told that an ERMI is the standard and then someone else says to test a different way and that it is the only reliable test. If money were no object I would use every test out there because I know how sick the environment can make me because I have experienced it first hand. A good friend of mine has a beautiful house and it was about 4 years old when they went to have carpet replaced just for the purpose of decorating. Under the carpet was all this mold. There were no signs or smells. They moved out of the house and went through several mold specialists. They found a die hard industrial hygienist who knew of Eric the mold warrior and Dr. Shoemaker and was diligent that every bit of mold was cleared from her house. My friend and her husband and 2 kids had to move out for over a year as they would rip apart walls and floors and mold readings would remain high. They threw away most of their stuff and cleaned things (I know this is controversial) that were non porous with appropriate mold cleaners. Finally the mold levels inside went to safe or whatever standards make a place clean. The family finally returned to the house. There were so many over the top measures taken because my friend did not want her kids exposed. They had the money to do it and insurance was covering it as well. There home owners insurance is ridiculous now! About 6 months after they moved back in the industrial hygienist came back and tested at my friends request. Levels came back high in the kitchen although they had never been high in the kitchen before. The whole family was exhausted from moving out and finally back home that they chose to stay there and test again a month later. Mold was back down with the exact same test a month later. They did nothing to clear it between the two testing times and used the exact same testing. The industrial hygienist said she sees this often. Although she tests the outside and compares to the inside, she believes that mold from outside gets into the house more during certain times. She even said you do the best you can but nothing is totally reliable. My point is that although I believe that a clean air environment is optimal and we should all strive for it but its just not that easy and cut and dry. I also am engaged to a ridiculously healthy man. He is understanding to a point. Trying to convince him to spend hundreds or thousands on testing is nearly impossible. I certainly don't have it without his help. Without a doubt I believe in the Mycotoxin theory. That is why I am doing Brewers protocol. When I lived in the condo and became so horribly sick nothing helped me either. Even supplements made me sick. These same things I take now and they do help me. I know I am at least in a cleaner environment than I was! Its all so difficult to pull together! I truly would do extreme avoidance if it were at all possible. It is not!
