The Best Pleated Air Filters

The Filtrete 16x20x1 MERV 5 6-pack consists of pleated electrostatic air filters designed for standard HVAC systems in furnaces and air conditioners found in most American homes. Perfect for homeowners prioritizing basic air cleaning without advanced features, these filters target lint, household dust, and dust mite debris to create a fresher living environment.

Standout features include exclusive 3-in-1 technology with a 300 MPR rating, where charged fibers pull in particles more effectively than non-electrostatic options. In real-world use, they reduce visible dust on surfaces and furniture, while supporting efficient airflow to keep heating and cooling systems running smoothly through harsh winters and pollen-heavy springs. The pleated construction maximizes surface area for better capture over up to 90 days, and the precise actual dimensions ensure a snug fit without gaps.

Build quality reflects Filtrete's leadership in residential filtration, with sturdy frames that withstand typical US home conditions. A minor drawback is the basic filtration level, which does not address finer particles like pet dander or smoke.
