Filtrete 12x20x1, AC Furnace Air Filter, MPR 1900, Healthy Living Ultimate Allergen, 2-Pack
- ...ith exclusive Filtrete Brand 3-in-1 technology from 3M to trap unwanted air particles while letting cleaner air flow through.
- Attracts and captures microscopic particles such as smoke, cough and sneeze debris, bacteria and viruses—and large particles, including lint, household dust and pollen.
- Tip: The higher the MPR (Microparticle Performance Rating), the more particles the filter captures. Select 2500 or 2800 MPR to also capture ultrafine particles.
- Filtrete 1900 MPR (Microparticle Performance Rating) equates to MERV 13.
- 1550 MPR available in 4”, 4” slim fit and 5” air filters.
- For maximum performance, change your home air filter at least every 90 days for 1” filters, and at least every 12 months for 4” and 5” filters..
- 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.
- A dirty filter will slow down air flow and make the system work harder to keep you warm or cool – wasting energy. Sign-up for a filter change reminder program that works for you!.
