Using Merv 13 Air Filters to Help Prevent Coronavirus

The COVID-19 pandemic and its spread have helped make all of us more aware of specific health concerns and protections—including how to slow down the transmission of coronavirus and other contagions.

As variants continue to develop and mutate, the need to reduce COVID-19 cases remains a priority.


Individuals, families, and communities are the first line of defense against COVID-19. Recent reports on the virus underscore that early detection, self-isolation, and prompt medical attention are key to preventing serious illness and death.

That’s partly why, as the coronavirus spreads, more and more people are turning to MERV-rated air filters to reduce pathogens and keep our air clean and purified.

The understanding is that COVID-19 spreads from person to person when in close contact. Particles can also spread from an infected person through the air and land on surfaces or be inhaled by another person.

As cruise ship cases have shown, buildings with poor ventilation can further spread COVID-10 particles. This is where air filters, particularly MERV 13, can help.

What Are MERV Air Filters?

Minimum Efficiency Reporting Value has been an effective rating for air filters since 1982 when it was first discussed by ASHRAE (the American Society of Heating, Refrigerating and Air-Conditioning Engineers).

The MERV rating system indicates an air filter’s effectiveness in filtering particles, and is one of the most popular rating systems when comparing the performance of various air filters.


MERV ratings range from 1 to 20, with MERV 16-20 filters being typically used in nuclear power plants and hospitals, and MERV 8 filters being what most home HVAC systems use. The higher the MERV rating, the more pollutants it can trap.

MERV 13 air filters can block air particles between 0.3 to 1.0 microns in size. Along with trapping COVID-19 particles, these air filters can effectively trap the following:

  • Dust
  • Pollen
  • Pet dander
  • Dust mites
  • Mold and mildew
  • Smoke
  • Exhaust fumes
  • Viruses
  • Bacteria
  • Microscopic allergens

These state-of-the-art air filters are considered the highest-rated products for residential use.

If you or a household member suffer from allergies, asthma, or other respiratory issues, then the MERV 13 air filter could be the most beneficial air purifying product for your home.

Protect yourself and your loved ones by keeping the air you breathe as pure and clean as possible with a higher-rated air filter.

Can MERV 13 Air Filters Stop the Spread of COVID-19?

MERV 13 filters are rated for filtering virus particles within residences and commercial buildings. According to the EPA, a MERV 13 air filter can help your HVAC system potentially remove coronavirus from the air around you.

However, you should check your home’s HVAC to see if the system can support a MERV 13 rated filter.


Experts are still learning about the coronavirus and its variants, but the CDC has confirmed that improvements and upgrades to your home ventilation system can improve air circulation and help eliminate viruses like coronavirus from your home.

Of course, it’s important to remember that preventing the spread of coronavirus doesn’t just stop at installing a MERV 13 air filter.

Everyone should also follow current health guidelines, which may include vaccination, social distancing, wearing masks, and handwashing.

In tandem with these practices, upgrading your HVAC system could reduce the spread of coronavirus and its variants, especially within your home.
