Mold can grow anywhere it finds moisture and moderate temperatures, and if it begins to grow in your home, the spores can be detrimental to your family’s health, as well as to the structure of the building. There are several types of mold you may encounter in your home, ranging from allergenic molds that will irritate your senses to toxic molds that can do serious harm.
If you’re concerned that there’s mold in your house, you may benefit from using an at-home mold test. These kits are more affordable than calling in a professional, and they can help you get an idea of whether you need to seek help from a mold remediation company. Some at-home kits simply have you take swaps to be sent out for lab analysis, while others provide you with the means to run the test yourself using a petri dish—just like in high school science class.
Here, the best at-home mold tests you can buy.

One of the top-rated options you can buy is the Mold Inspection Network DIY Mold Test, which allows you to collect up to three samples for analysis. This kit includes three tape lift samples, a quick-start guide, and a mold inspection booklet.
To use this test, you collect samples from surfaces that you suspect may be growing mold—the booklet provides instructions on where to look and how to get the best sample. From there, you mail the samples to the company’s lab (shipping isn’t included), and they’ll analyze the swabs and email you an illustrated data report that details whether there is any fungal growth and what type of mold was found. The company’s turnaround time is extremely fast and the results are comprehensive and useful. However, keep in mind that this kit only works on surfaces, so it won't be able to detect airborne mold spores.
