Mold spores in the atmosphere of living spaces can pose a risk to both humans and pets. Some individuals may experience immediate reactions such as coughing or constant sneezing upon entering an area that is polluted with airborne mold.

Mold air testing involves collecting and analyzing air samples to test for the presence and concentration of mold spores in the air. The test can help you tell if you have mold in your house that needs to be removed. In most cases, the presence of mold in the air is a sign that you have a significant mold problem.

There are several ways to test for mold spores in the air, most involving the use of an air sampler or mold testing devices. You can purchase mold testing devices and air samplers and do the tests on your own. However, it’s always advisable to have a trained mold inspector do the testing for more accurate results.

Here is how to test for mold spores before you order for a comprehensive mold inspection and remediation.

Requirements

  • Mold testing kit- Look for a mold testing kit in your local home improvement store or online that includes an air sampler. You can purchase a simple mold testing kit for as little as $20 although you need to be sure that the device is working as advertised and has good reviews.
  • Protective gloves and face-coverings- You need these if you will be going into a disused house, basement, or attic where you are certain that there is significant mold in the air.

Mold air testing should be done over a number of days and in different rooms for more conclusive results. If possible, send the kit to a certified mold expert for further analysis to check for the type of mold or for the presence of microscopic mold.

Step 1- Preparing your room

You will have more accurate and faster results if you can seal off the room where you suspect that there is mold in the air. Small spaces such as bathrooms, attics, or basements should be sealed before the air test. You can also do the same for larger spaces such as living rooms if possible.

Close all the windows and doors in the area where the test will be done at least twenty-four hours in advance to prevent mold particles from escaping. Also ensure that any air purifiers, fans, and AC systems that may disturb the air are turned off during the sampling/collection phase. This will allow for any floating mold particles to remain in the air.

Step 2- Prepare your Testing kit

There are different types of mold testing kits available in the market. Each of them comes with specific instructions on how they should be used. However, standard air testing kits have what looks like a petri dish with an airtight lid. The petri contains laboratory-prepared mold food (microbial culture) that is important for mold growth.

To prepare your test kit, unpack it as per the instruction manual accompanying it and
