Filtrete filters were created to both help protect your furnace equipment AND clean the air passing through your filter. Our filters improve your indoor air quality by attracting and capturing allergy-aggravating microparticles. Your air is cleaned each time it re-circulates through the filter.

Filtrete 20x25x4 MPR 1550 Air Filter, made by 3M, helps capture unwanted particles and allergens from your household air to contribute to a clean home environment.

Filter media is a mix of fiber and air, and it's often pleated. In fact, Filtrete™ Filter media is less than 15 percent fiber; the rest is air. This very low density allows air to easily flow through the media.

MPR 300: Dust, pollen, and lint. MPR 600: All of the above plus dust mites, and mold spores. MPR 1000-1200: All of the above as well as smoke, smog, cough, and sneezes. MPR 1500-2800: All of the above in addition to bacteria and some viruses.

Filtrete Air Filters imply that they are as good as air purifiers but are not in the same category or performance arena. Filtrete air filters are built to work with homes equipped with forced-air heating and cooling systems. Simply put, Filtrete is not the best choice for your home and the air quality inside of it.

The higher the MPR (microparticle performance rating), the more microparticles it will capture, making the 1550 ideal for asthma and allergy sufferers!

Microparticle Performance Rating MPR stands for “Microparticle Performance Rating.” MPR is the measure of the filter's ability to trap air particles smaller than 1 micron. MPR ratings range from 300 MPR (Basic) to 2800 MPR (Premium).

1500 MPR has a rating of MERV 12. The higher the MPR, the more microparticles--such as pollen, pet dander, smoke, bacteria and viruses--your filter will capture from the air passing through it.

The higher the MPR, the more microparticles - such as pollen, pet dander, smoke, bacteria and viruses - your filter will capture from the air passing through it. Now that you have found your filter, find it at a location near you and sign up for reminders to change it on time.

CR's take: The Filtrete Ultra Allergen Reduction 1500 MPR filter earns a Very Good rating for removing smoke, dust, and pollen from the air with the system running on a high fan speed, but it's only average when running on its lowest speed. In both cases, airflow through the filter is strong.

HEPA Filters High-efficiency particulate air 1. HEPA Filters. High-efficiency particulate air (HEPA) filters are recommended by the U.S. Department of Health because they are able to remove at least 99.97% of airborne allergens and pollutants - including mold spores and dust that are as small as 0.3 microns.

CR's take: The Filtrete 1900 Maximum Allergen Reduction filter is impressive at removing dust, pollen, and smoke from the air when the HVAC system is running on its highest fan speed, earning an Excellent rating in that test. But at the lowest speed, the filter is only average at removing those same airborne particles.

HEPA filter Air purifiers with a HEPA filter tend to be the best for filtering dust from your space. According to the EPA, HEPA filters can remove 99.97% of dust particles that measure 3 microns in diameter.

Better home air filtration: MPR 800 to 1200D This level is the better option if you want to capture lint, household dust, dust mite debris, mold spores, pollen and pet dander.
