Best At-Home Mold Tests

The Spruce / Chloe Jeong

Mold can grow anywhere it finds moisture and organic nutrients, like wood or paper, to feed on. You may find it in a corner of your bathroom, laundry room, or basement, or any space that doesn't have quality ventilation. If you come across mold, it's imperative to remove it quickly and safely, as mold can be detrimental to your family’s health. However, it can be a little difficult to know if mold exists in your home (especially if it's airborne), which is where at-home mold testing comes in.

Mold testing kits help you detect and even identify growing spores in your home, through samples collected via the air or from the surface in question. Some give you results right away, while others ask you to package the samples and send them back to a lab for professional examination. With the resulting information, you can get the peace-of-mind that you're looking for while making all of the necessary arrangements to remove the harmful fungi, or know your cleaning efforts were effective.

The Centers for Disease Control and Prevention (CDC) recommends removing every type of mold as soon as it's spotted, as you don't know how it'll affect you or anyone else in your household. There is no acceptable amount of any type of mold, and you should prioritize cleaning up spores—whether it be with the proper cleaning products or help from a mold remediation company if there's 10 square feet or more of affected area.

Plus, you should consider working with a professional for this task, and check that the testing follows methods from the American Industrial Hygiene Association (AIHA) and other professional organizations, as noted by the U.S. Environmental Protection Agency (EPA). After the fact, the results of at-home mold testing can help you create a prevention plan and recognize a mold-free area.

Here, the best at-home mold tests, that are both easy to use and effective.
