If you see or smell mold, you don’t need a test kit to tell you it’s there. Generally, it’s not necessary to identify the species of mold growing in your home, according to the national Centers for Disease Control and Prevention.
If mold covers an area less than 10 square feet, you may be able to eliminate the problem yourself. Larger areas require a pro. When we tested the kits below for our report, we found significant shortcomings in all of them, flaws that were serious enough to earn each a “Not Recommended” Rating.
