Having suffered a mold sinus infection for several years I finally did my own research and discovered Purified Environments. My research told me no amount of medication or surgery is likely to resolve the problem if your home environment isn't cleaned. So we removed our carpets and installed the Purified Environments system that runs off our AC and kills mold and other viruses in the home. I am now free of mold in my home and in my body! My oxygen level went from 70% to 100% I can now breathe! Thank you Purified Environments for helping me finally get the relief I needed to be healthy again!
