Minimum efficiency reporting value is what we use to describe MERV. An air filter’s efficiency rating will inform you how much dust and allergens it may collect before it needs to be replaced. Up to 75% of all airborne particles 0.3 microns or higher can be removed with a high-ranking MERV 13 to 16.

Almost all modern air filters are given a grade on the MERV scale developed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE). Use this rating system to find the best air filter for your home or office.

A filter’s ability to trap and remove particles is measured in terms of its Minimum Efficiency Reporting Value (MERV). A higher MERV rating indicates that more pollutants and allergens will be trapped by the air filter, which is obviously preferable

What is HEPA Filter?

One of the most effective air filters is the High-Efficiency Particulate Air (HEPA) filter. Airborne particles larger than 0.3 microns, such as pollen, mold spores, and dust mite allergens, can be captured by this high-tech, wide-bore device by as much as 99.97%.

However, before utilizing them, ventilation system capacity should be addressed as the airflow limitation of these filters creates a pressure drop. A portable air cleaner is an option when installing high-efficiency air filters is not possible due to poor ventilation. An existing ventilation system can be retrofitted to achieve at least a MERV 13 rating.
It may come as a surprise, but HEPA and MERV filters each have their own set of benefits and drawbacks that should be weighed carefully before making a purchase.
