"Thanks for posting this. We ran a test on bho extract. Ran a 5gal bucket full of the nastiest Mold we had. We had it tested and to our amaze it passed the mold tests with flying colors. So I told him what we did and he ran it again for me. Same results. So from your arrival I would have to assume that the packing of the material and the micron screens I run did the trick for filtering. I would like to here you point of view on this. Thanks again for the article. "
