Hart Cooley 276180240 Fiberglass Air Filter 18x24x2

Product Description

The HART COOLEY 276180240 is a fiberglass disposable air filter sized at 18 x 24 x 2 inches and weighing 2 pounds. It is designed for use in forced-air HVAC systems where low-cost, single-use filtration is required. The fiberglass media captures larger airborne particles such as dust, lint, and debris, protecting the blower and heat exchanger from fouling. This filter is sold individually and is a standard choice for residential and light commercial applications where frequent filter changes are part of a routine maintenance schedule. HVAC technicians and building maintenance personnel install this filter type during seasonal tune-ups and planned service calls.

This filter fits standard 18 x 24 x 2 inch filter slots found in residential furnaces, air handlers, and return-air grilles. It is appropriate for systems where basic mechanical filtration is sufficient and where higher-restriction media such as pleated or MERV-rated electrostatic filters are not required or specified. The disposable design means no cleaning or reconditioning is needed between service intervals.

Installation Notes

Installation is performed by HVAC technicians or qualified maintenance personnel. Always set the system thermostat to off and shut down the air handler or furnace at the disconnect before removing the existing filter. Insert the new filter with the airflow direction arrow pointing toward the blower. Inspect the filter rack and surrounding cabinet for bypasses or gaps that would allow unfiltered air to enter the system.
