MERV 11 furnace filters are designed to effectively trap a wide range of particles, including pollen, dust, lint, dust mites, mold, smoke, pet dander, smog, car emissions, bacteria and other fine particles. This type of filter is ideal for pet owners and those with mild allergies or asthma, as it offers more filtration than the MERV 8 filter but not as much as the MERV 13 (the highest option suggested for residential use). Although slightly more expensive than other filters, at a cost of a few dollars, they can help improve indoor air quality and provide relief to those with respiratory problems. MERV 11 air filters are capable of blocking at least 65% to 79% of particles in the air in the 1.0 to 3.0 micron size range. This type of filter can increase indoor air quality by removing 85% of micron-sized air pollutants while also maintaining the efficiency of the HVAC unit.
In addition to trapping pollen, dust, lint and mold, MERV 11 filters can also capture pet dander, smoke, smog and air from coughs and sneezes. The MERV 11 filter media is electrostatically charged and constructed of spun microfiber that does not retain moisture which can cause microbial growth. Filter King offers a convenient MERV 11 air filter subscription service so you never forget to replace your air filters. MERV stands for Minimum Efficiency Reporting Value and is the primary rating system used for air filtration. MERV 11 filters trap 65 to 79 percent of the average particles 1.0 to 3.0 microns in size with an average particle size efficiency of 85 percent or better.
