Merv 13 air filters are a great way to improve the air quality in your home. They are designed to capture more particles than a typical MERV 8 filter, but not as many as a HEPA filter. A MERV 13 filter will trap less than 75% of air particles that are 0.3-1.0 microns in size, which is not enough to capture the coronavirus (which is 0.1 microns). However, they can still provide a significant improvement in air quality. The Minimum Efficiency Report Value (MERV) is used to measure a filter's ability to capture particles between 0.3 and 10 microns.
The worst percentage of the six tests is selected as the official measure used to determine the MERV rating of a filter. Any air filter rated higher than 13 will restrict airflow to the point that it could damage your HVAC system, creating additional expense to repair it. In addition to upgrading your air filter to a MERV 13, there are other secondary precautions you can take to protect yourself from diseases. These include regularly cleaning and replacing your air filter, following the manufacturer's recommendations for maintenance and replacement. Merv 13 air filters are effective in controlling airborne bacteria, most tobacco smoke and contaminants released by sneezing, as well as dust, pollen, dust mites and pet dander.
They can also be used in industrial, commercial, office, hospital and university buildings, or anywhere where more efficient air filtration is desired to eliminate airborne pollen, allergens and germs. It's important to consult with a professional and make sure you get the right air filter for your home. We recommend replacing the filter regularly to ensure that the air is kept clean, energy costs are reduced, and that the air conditioner works properly.
