Outperforms fiberglass, washable and non-electrostatic 3-month pleated 1" air filters for your furnace, air conditioner, or HVAC system. Exclusive Filtrete Brand 3-in-1 technology from 3M traps unwanted air particles, while letting cleaner air flow through. Attracts and captures large particles such as lint, household dust, dust mite debris and mold spores. Filtrete 300 MPR (Microparticle Performance Rating) equates to MERV 5. For optimum performance, change your home air filter every 90 days or sooner. For residential use only. 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.
