How many tests do I need for my home? Is there a square footage limit?

The Dust Test is a screening test designed to cover your entire home, so you only need one! There is no square footage limit. If you think about how dust disperses freely throughout a home, the same principle applies here. The test will tell you about the levels of mold, mycotoxins, and/or endotoxins present in your home environment overall.
