The 3M Filtrete 1500 Series deep pleat furnace filter is a high-capacity HVAC air filter designed for central air systems and furnaces that use 5-inch thick filter housings. With dimensions of 16" x 25" x 5", this filter's deep pleat construction provides significantly greater surface area than standard 1-inch filters, allowing for superior dust-holding capacity and longer service intervals.

Powered by 3M's exclusive Filtrete 3-in-1 Technology, this filter traps unwanted airborne particles while allowing clean air to circulate freely. It captures microscopic contaminants including smoke, cough and sneeze debris, bacteria, and viruses, as well as large particles such as lint, household dust, pollen, and pet dander. The filter carries an MPR 1500 rating and is MERV 12/13 rated, placing it in the upper-middle tier of residential air filtration performance.

This filter is Certified Asthma & Allergy Friendly, meeting the standards set by the Asthma and Allergy Foundation of America. It is sold as a 2-pack, offering an extended supply. 3M recommends replacing the filter at least every 90 days for optimal performance, though deep pleat filters typically last longer than standard 1-inch filters due to their higher holding capacity.
