Trane F18252 Pleated Air Filter 18x25x2 Merv 8 10

Product Description

The TRANE F18252 is a pleated replacement air filter rated at MERV 8 and MERV 10, sized 18x25x2 inches to fit standard residential air handling equipment. Pleated filter media increases surface area compared to fiberglass flat-panel filters, improving particulate capture efficiency for dust, pollen, mold spores, and pet dander. This filter serves as a direct OEM-style replacement in TRANE air handlers and furnaces where the 18x25x2 nominal size is specified. Licensed HVAC technicians and knowledgeable homeowners can install this filter during routine maintenance without special tools.

This filter is suited for residential forced-air systems where consistent indoor air quality and equipment protection are required. It is typically installed in the return-air filter slot of a furnace, air handler, or media cabinet. The MERV 8 to MERV 10 rating range balances airflow resistance with filtration effectiveness, making it appropriate for most residential HVAC applications. Regular filter replacement on a schedule appropriate to system use and local conditions helps maintain system static pressure within design limits and protects heat exchangers, evaporator coils, and blower components from debris accumulation.

Installation Notes

Installation is performed by a licensed HVAC technician or qualified service professional. Before replacing the filter, set the thermostat to off and confirm the blower has stopped to prevent unfiltered air from bypassing the media during changeout. Note the airflow direction arrow printed on the filter frame and orient the filter so airflow travels from the return side through the media toward the blower. Do not operate the system without a properly seated filter, as unfiltered airflow can foul the evaporator coil and blower wheel.
