Cleaner air and easier maintenance

The Filtrete 18x18x1 MERV 5 six-pack is crafted for standard furnace and air conditioner systems. With actual dimensions of 17.81 × 17.81 × 0.81 inches, these filters fit neatly into 18x18x1 slots, helping maintain steady airflow while reducing visible dust settling on surfaces between changes.

Manufactured with electrostatic filtration, the media behaves like tiny magnets, attracting and capturing airborne particles as air passes through. This 3-in-1 technology targets lint, household dust, and other large-particle contaminants, all while promoting a smooth airflow that supports consistent system operation. The MPR 300 rating signals a strong performance against common dust and debris found in homes, offering a practical option for daily living without claiming medical benefits.

Key benefits you may notice

  • Electrostatic fibers attract a broader range of particles than non-electrostatic filters
  • Pleated design enhances durability and helps maintain steady airflow
  • Three-month replacement cycle supports predictable maintenance planning
  • Versatile compatibility with most standard furnaces and air conditioners

In real-life use, a six-pack provides flexibility for multiple rooms or building a ready-backup supply. Regular filter changes can help your HVAC system operate more smoothly, potentially supporting energy efficiency and keeping surfaces dust-free longer. Filtrete also offers smart reminders via the Filtrete app to help you stay on track without guesswork.

Usage tips

  • Plan replacements around a 90-day cycle, adjusting for home conditions
  • Ensure a proper seal around edges to optimize filtration and airflow
  • Consider earlier changes in homes with pets, higher dust exposure, or frequent occupancy
