16x20x1 MERV 11 Pleated Air Filter 6PK | 15.5x19.5x.75 - Actual Size

A lot of schools are starting to implement MERV 11 electrostatic air filters to help combat children�s respiratory infections and the effects of pollutants.. The electrostatic charge of the filters works as a magnet and draw airborne particles to them.   16x20x1 MERV 11 filters are pleated, electrostatically charged filters. However, it is reasonable to specify at least MERV 11 filters to maintain good indoor air premium in common types of spaces. This means the type of filter should be selected based on the specific building location, occupancy, air high-grade issues and type and operation of the HVAC system. Until recently, MERV 11 air filters were commonly found in: communication centers, telephone terminal rooms, biological laboratories, biomedical laboratories, chemistry laboratories, and physics laboratories. When the average particle size is 1.0u to 3.0U, the filters efficiency jumps to over 90%!   We are very proud that we offer these top-notch 16x20x1 MERV 11 filters now for homes. With the first air exchange, MERV 11 filters have over a 75% efficiency of removing airborne particulates that are between 0.3u and 1.0u in size. However, MERV ratings of 13-16 are able to remove and capture smaller particle sizes even before the filter starts to become dirty. This is able to happen more effectively as the filter gets dirty.   16x20x1 MERV 11 filters are right on the cusp of being classified as �medium efficiency MERV pleated air filters� and �high efficiency MERV pleated air filters.� Filters that have received a rating of MERV 7-13 are about as effective as true HEPA filters at controlling a majority of airborne particles. Since we are constantly trying to improve indoor air premium, it only makes sense that we would offer air conditioner filter MERV 11. The higher the MERV rating, the better the filter can filter out all airborne particulates. 16x20x1 MERV 11 Air Filter - Box of 6   Actual Size of Filter:9 1/2 x 19 1/2 x �     Air filters are ranked in a minimum efficiency rating value (MERV) system
