With different people seeking effective ways of protecting themselves from any airborne transmission of the COVID-19 virus and any other airborne transmission, many products on the market boast of being the best for use in residences and businesses. However, one basic and essential step towards limiting the risks of COVID-19, as suggested by most health safety organizations, would be to have an upgrade of the air filter of the building to a better one rated to the level of MERV 13 or even higher.


MERV is simply the Minimum Efficiency Reporting Value of any air filter. Its ratings note the air filter’s abilities and efficiency level when considering its filtration. The MERV rating system is widely utilized in the HVAC industry and was developed by the American society of heating, refrigeration, and air condition engineers. 

When talking about air filter capabilities, an air filter with a low MERV rating can block particles like dust. Still, one with a higher MERV rating can efficiently block microscopic particles like smoke molecules. This is due to its tighter mesh wave. Areas requiring more filtration will get better results with a high MERV rating. The greater the rating, the smaller the particles that’ll be filtered can be. 

As we all know, particles vary widely in size, from 0.3 microns to 10 microns. So, filters with MERV air filters protect you from various airborne contaminants. These contaminants include; mold, pollen, dust, bacteria, smoke, dust mites, pet dander, virus carriers, and exhaust fumes.


MERV 13 air filters are quality-grade air filters recommended for home use. An air filter with a rating of at least 13 will obstruct the flow of air to the point that could damage your HVAC system, leading to added expenses to repair it. MERV rating system ranges between 1 to 20, the peak (20) being the recommended for hospitals. People that should consider using MERV with a rating of 13 include those with:

  • Allergies
  • Asthma
  • Newborn baby
  • Chronic bronchitis
  • Lung disease
  • Emphysema
  • Chronic obstructive pulmonary disease
  • An already weakened immune system
  • Uses an inhaler, oxygen tank, or ventilation machine
  • Someone in a home that smokes constantly. 

With MERV 13 air filters, you’ll get the cleanest air quality needed in your home. Below are contaminants your MERV 13 filters can scrape out that a low-rated filter would find it hard to; 

  • Microscopic allergens
  • Bacteria
  • Viruses
  • Tobacco smoke


When seeking to purchase air filters, cheaper options with lower MERV lower ratings may look like a good option compared to MERV filters that are highly rated. However, this may not be the best option as only a higher MERV-rated air filter would leave your home cleaner and safer for everyone in the home. Though purchasing a lower MERV-rated filter may save some money, come to think of it, are those dollars work depriving you of quality air? You might choose to guess, but we all know the answer is “no.”
