MERV in relation to your heating and cooling sytem 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 better at capturing 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 permit more air to go through the filter, which can assist the operation of the HVAC system. It’s important to have the appropriate mix of air filter and MERV rating for to meet your home’s needs and your system. Call Francis Home Environment Heating and Air Conditioning in Ottawa today to see which MERV rating is ideal for your home and family.
The American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE), which created 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, purchase an Air Purification System, which comes with a MERV 16 media filter, and you’ll be in good shape for years.
