3M 7100222948 Filtrete Allergen Filter 20x25x1

Product Description

The 3M 7100222948 is a residential air filter from the Filtrete Ultimate Allergen Reduction line, designed to capture a broad range of airborne contaminants in forced-air HVAC systems. Unlike standard one-inch filters rated for three-month service, this filter is engineered to attract and trap microscopic particles including bacteria, particles that can carry viruses, and odor-causing matter. At 20 inches x 25 inches x 1 inch, it fits a common residential filter slot and is installed by HVAC technicians or knowledgeable homeowners during routine maintenance. The filter uses an electrostatically charged fiber matrix to pull particles toward the media rather than relying solely on mechanical interception.

This filter is intended for residential forced-air heating and cooling systems. It targets households where air quality is a priority, such as those with allergy or asthma concerns. The 20 inches x 25 inches x 1 inch footprint covers one of the most widely used residential filter sizes, making it a straightforward drop-in replacement during seasonal filter changes. It is not rated for commercial or industrial air-handling applications.
