Why MERV 13 Filters are the Best Option for Clean Indoor Air Quality

Minimum Efficiency Report, or MERV, values measure a filter's ability to capture particulate matter. Filters with a MERV-13 rating or higher are capable of trapping smaller particles, including viruses. MERV ratings range from 1 to 20, with higher numbers indicating a higher percentage of contaminants blocked by the filter. The Merv 13 Green Pleat was designed to meet the air filtration efficiency standards set out in LEED programs for existing buildings and new construction, as well as an effective IAQ tool for LEED in schools.

This filter is able to provide the strongest possible protection without compromising the reliability of the HVAC system fan. Simply replacing the existing lower efficiency pleat or disposable air filter with the Green Pleat can upgrade the system to the MERV 13 level required by the LEDs. MERV 14 and higher filters can capture particles that are even smaller than previous MERV ratings, ranging from 0.3 to 1.0 microns in size. The charged fibers allow the Green Pleat to reach MERV 13 levels after installation and immediately trap contaminants in the air.

Six Reasons Why Upgrading Your Filter to MERV 13 is Essential

1.Compromised HVAC Ventilation Performance: Using an air filter with a MERV rating higher than recommended by the manufacturer of your oven or air conditioner may impair its performance.2.Inadequate Filtration: A MERV 13 air filter will provide the strongest possible protection without compromising the reliability of the HVAC system fan.3.Clean Indoor Environment: If someone needs a clean indoor environment for health reasons, a MERV 13 air filter is the best option.4.Capture COVID-19 Virus Particles: Filters with a MERV rating of at least 13 will efficiently capture COVID-19 virus particles and could help reduce the spread of COVID-19 indoors.5.Smaller Particles: Filters with higher MERV ratings trap small particles more effectively than filters with lower MERV ratings.6.Portable Purification Controls: Portable purification controls can bridge the gap to provide adequate indoor air quality.


MERV 13 filters are an essential tool for providing clean indoor air quality and reducing the spread of COVID-19 indoors. They are capable of trapping smaller particles, including viruses, and can provide stronger protection without compromising HVAC system performance.
