20" x 20" X 1"  Filtrete® Ultimate Allergen Reduction Filter from 3M - # UA02DC - 6 Pack

The Filtrete® Ultra Allergen Reduction Filter carries a 3M Microparticle Performance Rating (MPR) of 1900 - roughly equivalent to a MERV 12 rating


  • 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 air

93% effective at capturing large allergens like:

  • Pollen
  • Mold spores 
  • Dust mite debris

Attracts and captures microscopic allergens like:

  • Smoke
  • Pet dander
  • Household dust
  • Smog
  • Bacteria
  • Particles that carry viruses
  • Particles that can carry odors

* 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.


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 0.3 and 1.0 micron. Based on independent laboratory tests, 3M's MPR measures a filter's ability to capture submicron particles that make up 99% of the particles in the air, such as bacteria, smoke and smog.

    Comments about 3M 20 x 20 x 1 Filtrete Ultimate Allergen Reduction Filter - UA02DC-6:

    The Ultimate Allergen is the perfect filter choice for minimizing allergy conditions around the typical household that pets have free roam in. Cost initially appears high however the overall performance is well worth the money. Ensuring that the filter is located correctly will also maintain coil cleanliness resulting in increased life of the AC unit.
