3M Company S-EA02-4 Smart Air Filter 20x20x1 4-pack

Product Description

The 3M COMPANY S-EA02-4 is a Filtrete Premium Allergen Smart Air Filter designed for residential forced-air HVAC systems. 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.

This 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.

Installation Notes

Air filters in this size class are typically installed by HVAC technicians or qualified service professionals during routine preventive maintenance. Always power down the air handler or furnace at the disconnect switch before accessing the filter compartment. Confirm airflow direction and install the filter with the arrow on the frame pointing toward the blower. The Bluetooth sensor must be paired to the Filtrete Smart app after installation to begin filter-life monitoring.
