As mentioned before, PUROH eliminates microorganisms present in the air, such as mold, fungi, or spores. By eliminating the spores, new colonies of mold cannot develop, reducing future mold spores present in the air. Mold is always associated with moisture, and its growth can be inhibited by keeping humidity levels below 50%. PUROH acts by denaturing spores and preventing their proliferation, while also eliminating harmful mycotoxins produced by some fungi.
