Filtrete 20x25x4 Furnace Air Filter, Healthy Living Ultra Allergen, 2-Pack

The Filtrete Brand 3-in-1 technology from 3M has been designed to outperform fiberglass, providing washable and non-electrostatic 3-month pleated 1 in. home air filters for your furnace, air conditioner, or HVAC system. These filters are engineered to trap unwanted air particles while allowing cleaner air to flow through, offering superior performance.

The filters effectively attract and capture microscopic particles, including smoke, cough and sneeze debris, bacteria, and viruses, as well as larger particles such as lint, household dust, and pollen. With a MERV 12 rating, the 1550 MPR filters are highly efficient in capturing a wide range of microparticles, including pollen, pet dander, smoke, bacteria, and viruses.

The higher the MPR (Microparticle Performance Rating), the more effective the filter is in capturing these small particles from the air passing through it. The 1550 MPR filters have a 54% small particle capture rate, which is particularly effective in capturing particles as small as bacteria and those that carry viruses, as tested according to the ASHRAE 52.2 standard for 0.3 to 1 micron particles.

These filters are certified as asthma and allergy friendly, as outlined in the ASCR: 1246-01 report, providing a healthier indoor air environment for your home.

The Filtrete 1550 MPR filters are available in various sizes, including 4 in., 4 in. slim fit, and 5 in. thick air filters, allowing you to find the perfect fit for your heating and cooling system or HVAC system.

For optimal performance and energy efficiency, it is recommended to change your home air filter at least every 90 days for 1 in. filters, and at least every 12 months for 4 in. and 5 in. filters. A dirty filter can slow down air flow and make the system work harder, wasting energy. To make the process easier, you can sign up for a filter change reminder program that works best for you.
