With our Cleanspace being made with a treated, non organic material it takes away the organic material factor that the mold needs to feed of off to live. then we have our Sanidry dehumidifiers that will take moisture out of the air while filtering it causing clean dry air to be pushed back in to the crawlspace and eliminating the moisture factor that the mold needs to grow.
