Select 2500 or 2800 MPR to also capture ultrafine particles.
- Filtrete 1500 MPR (Microparticle Performance Rating) equates to MERV 12.
- 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!.
