These machines are excellent at removing water from the air. Whether used after a flooding event or taken as a preventative measure, decreasing the amount of moisture in a home helps remove the number of available locations for mold to begin growing, making dehumidifiers great investments. The ideal humidity level in a home should be below 50 percent to avoid mold growth. Just remember to purchase a dehumidifier based on the size of the space you’re placing them. I personally recommend Aprilaire’s dehumidifiers. They offer a range of products, from whole-home dehumidifiers to single-room and crawl space dehumidifiers.
