3M Filtrete furnace filters bring the freshness of Spring without the allergies. 3M Filtrate filters are made of polypropylene and polyolefin plastic, which contain an electrostatically charged filter media. The filter acts like a magnet due to the electrostatic charge, attracting and capturing particles between 0.3 and 10 microns in size. The particles are caught within the filter's pleated fabric. 3M Filtrete filters capture dust, mold, allergens, viruses, bacteria, and other harmful air particles to leave the air in your home at its healthiest.
3M Filtrete filters are more efficient and outperform other standard washable, fiberglass, and non-electrostatic 1" air filters. 3M Filtrete filters use an independent rating for each filter's ability to capture particles and allergens. The rating is based on the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) air filtration test. 3M Filtrete filters are rated based on the Microparticle Performance Rating (MPR). The MPR measures a filter's ability to capture particles between 0.3 and 1.0 microns in size. The higher the MPR is for a 3M Filtrete filter, the more effective it is at eliminating contaminants in your home.
It is recommended that 3M Filtrete filters are to be replaced once every three months. When a 3M Filtrete filter isn't replaced according to the recommended suggestion, the filter can start to restrict airflow and increase your energy bill. Different conditions in a home can significantly compromise the effectiveness of a filter, which is why the 3M Filtrete filters should be checked once a month to ensure they are not clogged. These conditions include:
A home with more particles for the filter to capture will shorten the lifespan of the 3M Filtrete filter. A compromised filter will reduce the effectiveness and performance of the filter to keep your indoor air clean.
