Mold is a common problem in many homes, and having the right filter can make a significant difference in improving your indoor air quality. We always want make sure to help our customers choose the best MERV rating to effectively improve their home’s air.


Firstly, let's understand what MERV rating means. MERV stands for Minimum Efficiency Reporting Value, and it measures the effectiveness of an air filter. The higher the MERV rating, the better the filter is at capturing smaller particles, including mold spores.


For most homes, a filter with a MERV rating of 8 to 13 should be sufficient to filter out mold spores an other indoor allergens. These filters are capable of capturing particles as small as 3 microns. That will help ensure that you have cleaner air for you, your family, pets, employee, etc.

While higher MERV ratings offer better filtration, it's crucial to check your HVAC system's compatibility. We recommend that you do not go above a MERV 13 rating. Filters with higher ratings may restrict airflow, causing strain on your system. Therefore, it's essential to consult your HVAC technician to determine the highest MERV rating suitable for your specific system. We want our AC systems to work, and going too high with your filtration rating will suffocate you property. We want to make sure our homes breathe!


Remember, regular filter replacement is equally important in maintaining a mold-free environment. Check the manufacturer's recommendations for filter replacement frequency, and be sure to follow them. Normally we recommend that our customers switch their filters monthly. This will help filter out all the nastiness that is in our air, as well as help your AC run efficiently. Remember always, we want to make sure to take care of the lungs in our home.
