18 X 30 X 1 Filtrete Micro Allergen Reduction Filter from 3M - #9828 - 6 pack The Filtrete Micro Allergen Reduction Filter carries a 3M Microparticle Performance Rating (MPR) of 1000 - roughly equivalent to a MERV 11 rating Click here for detailed comparison of 3M Filtrete 1 Filters Features: Meets the American Lung Association Health House Indoor Air Quality Guidelines No unnecessary antimicrobial chemicals added; Filtrete filtering material will not support the growth of bacteria, mold, mildew or fungi in normal use Contains electrostatically charged media to filter and attract particles in the airAttracts and captures large allergens like: Pollen Mold spores   Dust mite debrisAttracts and captures microscopic allergens like: Smoke Pet dander Household dust Smog  This filter should be changed at least every 3 months.  Certain conditions in your home will significantly add particles to the air - this will cause the filter to capture more particles, shortening it's life to less than 3 months.  These conditions would include: dirty ductwork, pets, construction work, sanding projects, tobacco smoke, burning candles, fireplaces and wood-burning stoves. WHY USE MPR RATHER THAN 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. One part of MERV reports a filter's ability to capture medium to large particles between 1 and 10 microns. This value is helpful in comparing the performance of different filters but it is not adequate alone because particles greater than one micron make up only about 1% of the contaminants in your indoor air. Another part of MERV addresses submicron particles. 3M calls this the MPR or Microparticle Performance Rating. It measures a filter's ability to capture particles between 0
