Best Mold Detection Meters and Mold Tests for Your Home

Mold problems can crop up in your home out of nowhere. Mold tends to recur in certain areas in your house from time to time, such as bathrooms, kitchens, basements, and even cellars.

Any part of the house with more moisture can easily invite and promote fungal growth. Although some homeowners are naturally skilled in detecting mold and mildew by their smell or color, not all can spot the growth, especially in the initial stages.

Using mold detector kits to test your house is a much safer and more effective alternative. These kits are handy and provide accurate and detailed results about mold growth.

You can then use these results to secure your living space and make it mold-free. Look at the top mold detectors below to choose the best one for your home.

How Does a Moisture Meter Help Detect Mold Growth?

Mold grows in dark and humid places. These include near the toilet seat, behind the kitchen sink, or in parts with water leakage. Areas with constant flooding and rainfall also have the highest rate of mold growth.

Understanding which part of your house has the most moisture is important to stop fungal growth in the early stages. A moisture meter is the best way to detect which place in your house has enough moisture to facilitate mold growth.

There are separate moisture meters for concrete and wood houses. The device is attached to a wall, floor, or ceiling to detect the moisture content in the material. A pin moisture sensor uses an electric current to detect moisture content.

Meanwhile, a pinless moisture meter uses high frequency to sense the moisture content in a material. Both types of moisture meters are essential to understand which part of your house has access to water that can be an ideal atmosphere for mold to grow.

Can a Mold Test Detect Spores in the Air?

Mold detectors collect samples of air or the surface material of a home to check for mold and mildew. If mold spores are in the air, the kit can easily detect them and show them in the results. Then, the sample is tested in a kit at home or in a lab for three to four weeks.

Air sampling is the best way to detect mold spores. These spores are not only harmful to health. But since they travel through the air, they can contaminate other parts of the house too.

A test kit might not be able to detect spores inside the walls. So, it is important to sample and test the air in the room to check for spores. The results of this test can also help you understand the severity of the mold infestation.
