Best Mold Detector and Air Sensor

Many people don’t realize that the air in their home is often more dangerous than the air outside. Unfortunately, mold is a big reason for this issue. Mold can cause indoor air quality issues and a number of health problems. Specifically, mold can cause allergies, asthma, breathing problems, and chronic health conditions. There are two ways to prevent and detect mold growth. First, you can use an air quality sensor or moisture detector to test for organic compounds in the air and find sources of moisture in your wood or drywall. Next, you can test for mold using two different types of mold detector test kits (dust and physical sample). We have tested and reviewed several products to find the best mold detector for your home DIY mold remediation.

How to Detect and Prevent Mold Growth

One way to prevent mold in your home is to detect its signs either before growth occurs or during early stages of growth. There are two early signs to be aware of:

  1. Areas of moisture
  2. Mold Spores in the air

Mold thrives in damp environments. Be sure to check your home for areas of moisture. In many cases, these areas will be apparent. However, sometimes moisture can be hard to find. This is where a moisture sensor comes into play. A moisture sensor will help you detect areas of high moisture in your drywall, wood, and other places in your home. Catching this moisture early will not only prevent mold growth, but also prevent large home repair costs.

In order to detect mold spores in the air, you will need an air quality sensor. An air quality sensor has the ability to detect minute organic compounds in the air. Specifically, these sensors can detect mold spores. Mold spores are released from areas of mold growth. These spores are the cause of allergies and asthma and also foster the spread of mold throughout your home.

Signs of Mold Growth – What to look for

There are several signs of mold growth in your home. There are both visual signs of mold and body reaction signals.

  • Mold odor
  • Moisture and water damage
  • Water leaks
  • Visible mold growth
  • Sneezing
  • Asthma or difficulty breathing
  • Itchy throat
  • Coughing
  • Itchy eyes
  • Itchy skin

First, check high-risk areas for signs of water damage, musty odor, or moisture. These areas include your basement, cross base, under the sink, showers, attic, laundry room, and corners of the house. If you don’t see any signs of mold growth, you might be able to smell it. Mold smells musty. Similar to the odor released from wet wood, dirty clothes, and moss.

Other signs of mold include allergy symptoms such as sneezing, asthma, itchy skin or throat, coughing, or itchy eyes. If these symptoms persist while spending time in your home or in certain rooms, then you might have a mold problem.

How to Remediate Mold

Mold remediation is actually a simple process. Finding the mold and preventing the future growth of mold is the most difficult part.

To remove mold from a surface in your home, first purchase a good mold remover. Next, use a bristle brush to scrub the surface with the mold remover. After scrubbing off the mold, ensure that the remover solution soaks into the surface. This will help kill any remaining mold.
