The Filtrete® Elite Allergen Reduction Filter carries a 3M Microparticle Performance Rating (MPR) of 2200 - roughly equivalent to a MERV 13 rating

Features:

• Meets the American Lung Association® Health House® Indoor Air Quality Guidelines
• Uses an electrostatically charged media to attract and filter debris found in your home
• With normal use, this filters material will not support the growth of mold, mildew, fungi, or bacteria. Does not contain unnecessary antimicrobial chemicals

MPR COMPARED TO MERV RATING?

The Heating, Ventilating and Air Conditioning (HVAC) industry uses the ASHRAE 52.2 Standard, which assigns a Minimum Efficiency Reporting Value (MERV) to a filter. The MERV reports a filter's ability to capture particles between 1 and 10 microns. When comparing the performance of different filters, it is helpful to use the MERV rating. The MERV rating is limited though because only about 1% of your indoor air contaminants are greater than 1 micron.

The Microparticle Performance Rating (MPR) measures submicron particles between .3 and 1.0 micron. 3M's MPR is able to measure a filters capacity to capture those submicron particles such as smoke, smog and bacteria.  This is valuable because submicron particles make up 99% of the particles in the air, making the MPR a better reporting value.
