What is a MERV 13 Filter?
A MERV 13 filter is a common standard cardboard frame pleated air filter. These types of filters are widely used in residential and commercial applications in varying MERV ratings. MERV 13 is the ‘highest’ rated in this product group, which range from MERV 7 – 13. The MERV rating refers to the filters ability to capture particles. MERV 13 filters capture at least 75% of air particles sized 0.3-1.0 microns. As the particle size increases a MERV 13 captures more. For example, a MERV 13 filter will capture at lease 90% of air particles sized 3-10 microns.
