Glasfloss 80055.012525 Pleated Furnace Filter 25x25x1

Product Description

The GLASFLOSS 80055.012525 is a 1-inch pleated furnace filter designed for forced-air heating and cooling systems in residential and light commercial applications. Measuring 25 inches by 25 inches by 1 inch, this filter installs in standard filter slots to capture airborne particulates including dust, pollen, and debris before they reach the air handler or furnace heat exchanger. Sold as a case of 12, it is suited for service contractors, property managers, and facilities maintenance professionals who stock filters for recurring preventive maintenance. The pleated media construction provides greater surface area than standard fiberglass panel filters, supporting better particulate capture over the service interval.

This filter is used in residential gas furnaces, electric air handlers, and split-system HVAC equipment with standard 25x25x1-inch filter compartments. The case quantity makes it practical for multi-unit residential buildings, commercial facilities, or service companies maintaining multiple accounts. Standard 1-inch depth fits the most common filter rack configurations found in residential and light commercial equipment without modification.

Installation Notes

Filter replacement is a routine maintenance task typically performed by HVAC technicians or trained maintenance personnel. Always set the system thermostat to off and confirm the air handler or furnace blower has stopped before opening the filter access panel. Install with the airflow arrow on the filter frame pointing toward the blower, away from the return air duct. Replace filters at regular service intervals or sooner if the filter surface is visibly loaded with debris.
