This 4-pack of 20 x 20 x 1 inch filters uses electrostatically charged media to attract and capture microscopic airborne particles including bacteria, particles that can carry viruses, mold spores, and pollen. Each filter includes a built-in Bluetooth-enabled sensor that pairs with the Filtrete Smart app, allowing technicians and homeowners to monitor filter life and identify the optimal replacement interval based on actual usage conditions rather than a fixed calendar schedule.\u003c\/p\u003e\u003cp\u003eThis filter is suited for residential HVAC applications where allergen and fine-particle control is a priority. The 20 x 20 x 1 inch nominal size fits standard 1-inch filter slots in residential air handlers, furnaces, and heat pumps. The app-connected sensor makes this a practical choice for property managers or service contractors who maintain multiple units and want data-driven filter change scheduling rather than guesswork. Sold as a 4-pack in a single unit of measure.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCaptures microscopic particles including bacteria and particles that can carry viruses\u003c\/li\u003e\n\u003cli\u003eFilters large particles such as mold spores and pollen\u003c\/li\u003e\n\u003cli\u003eBuilt-in Bluetooth sensor pairs with the Filtrete Smart app for real-time filter life tracking\u003c\/li\u003e\n\u003cli\u003eApp-based replacement alerts based on actual airflow and usage data\u003c\/li\u003e\n\u003cli\u003eNominal size 20 x 20 x 1 inches fits standard residential 1-inch filter slots\u003c\/li\u003e\n\u003cli\u003eSold as a 4-pack for multi-unit stocking or extended service intervals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for residential forced-air furnace, air handler, and heat pump systems that accept a standard 1-inch nominal filter in a 20 x 20 x 1 inch slot.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eAir filters in this size class are typically installed by HVAC technicians or qualified service professionals during routine preventive maintenance.
