When it comes to purifying the air in your home, office, or business, you don't have to settle for just one filter. You can use multiple filters in a portable air purifier and reap the benefits of all of them. But what about using a MERV 13 filter? In this article, we'll explore the advantages and disadvantages of using a MERV 13 filter in your home air purifier. The SARS-CoV-2 particle is only 0.1 micrometers in size, but it clings to larger particles (0.3 micrometers) that are trapped by a MERV 13 filter.
This type of filter is designed to capture different substances and reduce the amount of dirt and debris in the air. However, it's important to make sure that the rest of the system is configured to handle the increased restriction created by the filters. High-efficiency particulate air (HEPA) filters are also an option when it comes to air filtration. Although their nominal values are not higher than those of a MERV 16, HEPA filters trap even smaller particles at a faster rate than a MERV 16 and are typically used in surgical operating rooms, clean rooms, and other settings that require absolute cleanliness. In light of the threat posed by COVID-19 and other germs, upgrading a building's air filter to a HEPA is much more effective than simply switching to a MERV 13. A MERV 13 will trap less than 75% of air particles that are 0.3 to 1.0 microns in size (the coronavirus measures 0.1 microns).
You can also use MERV 13 filters in portable filtration systems for an HVAC system with HEPA filtration. Many existing HVAC systems also find it difficult to adopt a MERV 13 due to the increased load on the fan caused by a finer filter medium, which can actually do more harm than good and reduce airflow if the system isn't designed to handle that type of filter. For commercial buildings, the EPA recommends using a MERV 13 filter to ensure clean air and adequate filtration. Ultimately, it's up to you to decide which type of filter is best for your needs. If you're looking for maximum protection from airborne pollutants, then a HEPA filter is your best bet.
However, if you're looking for an affordable option that still provides good filtration, then a MERV 13 may be your best choice.
