Filtrete 20x20x1 AC Furnace Filter - MERV 14, MPR 2500, 4-Pack | Certified Asthma & Allergy Friendly

Elevate your indoor air with Filtrete 20x20x1 MPR 2500

From the trusted Filtrete line, this 4 pack is designed to perform in standard residential furnaces, air conditioners, and HVAC systems. The 1 inch pleated design balances dense filtration with steady airflow, helping living spaces feel fresher and more comfortable. The filter is built to maintain strong air movement while it works to remove a broad range of particles as air passes through.

With a 2500 MPR rating and MERV 14 efficiency, this filter targets common household pollutants. In practical terms, it can help reduce pet dander, smoke residues, and bacteria in daily environments, and it interacts with ultrafine particles and virus-sized particles according to product documentation. In addition, it captures larger debris such as lint, pollen, and household dust, contributing to cleaner surfaces and ducts between cleanings.

Dimensions and fit are straightforward. The filter is marketed as 20x20x1 but measures about 19.63x19.63x0.78 inches in practice, forming a reliable seal in many standard slots. This 3 month pleated design is suitable for use in your furnace, air conditioner, or broader HVAC system. For best results, plan to replace the filter every 90 days, with more frequent changes in households with pets, smoke, or high dust levels. The design emphasizes even airflow across the entire surface so performance remains consistent as air moves through your system.

Maintenance is supported by smart tools in some setups. The Filtrete app can help you set reminders for 30, 60, or 90 days, keeping routine upkeep manageable. Filtrete is widely trusted in North America as a leading HVAC filtration brand, and this MPR 2500 model sits among high performance options within the line. While results vary by home and usage, many customers notice a fresher feel in the air when filters are refreshed on schedule.
