Air Filters and MERV Ratings

There are a few different types of air filters on the market for your HVAC system to choose from. Suppose you search for air filters in any search engine. You will see lots of results for the most popular filters available for purchase. Examples of some filters available are fiberglass, polyester, washable, pleated, and electrostatic filters. The filter ratings are based upon a system called the MERV or Minimum Efficiency Reporting Values system.


This system was created by ASHRAE, the American Society of Heating, Refrigerating, and Air Conditioning Engineers. This type of rating system is used to calculate the airflow of particles captured through the filter in micron measurements. This, in turn, gives the filter a rating from the least efficient to the best efficiency based on the air filter's ability to produce the reduction of dust particles in your home or business.
