Overview

Meet Filtrete 21x21x1 AC Furnace Air Filter, MPR 700, MERV 8, a 2-pack of 3-month pleated filters designed to balance strong filtration with smooth airflow through your heating and cooling system. The actual size is 20.81 x 20.81 x 0.81 inches, making it compatible with many standard furnace and air conditioner units.

Built with electrostatically charged pleated media, this Filtrete filter aims to attract and capture more particles as air passes through. In practice, that means your indoor air can feel crisper as the filter cycles through your HVAC system. The product line uses exclusive Filtrete 3-in-1 technology to trap unwanted particles while still allowing clean air to flow through.

  • 3-in-1 technology traps particles while letting cleaner air flow through your furnace or HVAC system.

Real‑world use

  • Ideal for homes during high pollen seasons, helping to keep common irritants in check without sacrificing airflow.
  • A good fit for pet households where pet dander is a concern, thanks to enhanced capture capabilities.
  • Designed for everyday use in standard 20–22 inch filter slots, balancing performance with ease of replacement.
