MERV here stands for Minimum Efficiency Reporting Value, a value that lets us know the size of particles an air filter is designed to catch. Higher MERV ratings are more likely to catch smaller particles. That’s why hospitals tend to use MERV 16 or higher, to capture the most pollutants possible.
Although lower MERV rated filters are less efficient overall, they allow more air to go through the filter, which can assist the operation of the HVAC system. It’s important to have the proper mix of air filter and MERV rating for your exact needs and your system. Call Mersey Heating and Air Conditioning in Toronto today to let our experts walk you through which MERV rating is needed for your home and family.
The American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE), which developed the MERV rating, recommends filters with minimum MERV ratings of 6. The U.S. Department of Energy recommends a minimum of MERV 13. For the best overall solution for most homeowners, acquire an Air Purification System, which comes with a MERV 16 media filter, and you’ll be in good shape for years.
