Filterbuy 20x25x4 Air Filter MERV 13, Pleated HVAC AC Furnace Filters (6-Pack)

The Measurement System: Minimum Efficiency Reporting Value (MERV) The MERV rating system measures a filter's ability to capture particles on a scale of 1 to 20, with 20 representing the smallest microns captured. This provides a standardized way to assess a filter's performance.

Standard Protection (90%): MERV 8 Air Filters These filters are perfect for almost any home or business seeking great indoor air quality at a reasonable cost. They capture 90% of airborne particles ranging from 3 to 10 microns in size, including dust, pollen, and lint.

Superior Protection (95%): MERV 11 Air Filters Designed for homes or businesses with additional air quality concerns, such as pets, smokers, or allergy sufferers, these filters capture 95% of particles from 1 to 3 microns, including smoke and bacteria.

Optimal Protection (98%): MERV 13 Air Filters For larger homes, businesses, and those desiring the best possible filtration, these filters trap 98% of particles as small as 0.3 microns, including bacteria and viruses, without restricting airflow.

Odor Eliminator (90%): MERV 8 Air Filters with Activated Carbon These filters provide reliable MERV 8 performance while also inhibiting unpleasant odors through the use of activated carbon.

Choosing the Correct Filter Size The nominal size, such as 16x20x1, is a rounded measurement, while the actual size, like 15.50x19.50x0.75, provides the filter's precise dimensions. Measure your current filter to find the right replacement.
