Exclusive filtration technology

Experience Filtrete 3-in-1 technology that combines a high MPR 1550 with a MERV 12 rating. This pairing aims to pull in a broad range of particles from the passing air and maintain steady, cleaner airflow through your system.

What it captures

  • Large particles such as lint, pollen, and household dust
  • Microparticles like pet dander, smoke residues, bacteria, and virus particles
  • Overall air quality improvements as part of your routine home maintenance

In practical terms, you may see up to 54% capture of virus airborne particles as air moves through the filter, illustrating the filter’s role within your HVAC system while keeping expectations grounded in non-medical framing.
