Mold is a rapidly growing fungus that can be found just about everywhere in nature. In areas that are regularly dark or damp however, mold levels can become problematic. Seeing mold growth, smelling a musty odor, or finding water stains are mold-growth indicators around the home. Unfortunately mold cannot always be seen. But when it is growing in the home, it is also present in the air which can trigger both allergies and asthma. The Mold Screen Check identifies and provides concentration levels for hundreds of types of molds. This do-it-yourself test kit is easy to use: collect a sample using the included one-surface sampling device, return it to the AIHA accredited lab, and results are emailed to you in 3-5 days at no additional cost.
