Aaf/flanders 84858.011818 Merv 8 Pleated Air Filter 18x18x1

Product Description

The AAF/FLANDERS 84858.011818 is a MERV 8 pleated air filter designed for residential forced-air furnaces and central air handlers. Constructed with 100% synthetic, wire-backed media and a clay-coated paperboard frame, it delivers reliable mechanical filtration across a standard 90-day service interval. At 18 inches x 18 inches x 1 inch, this filter fits a wide range of residential equipment and slots into standard 1-inch filter tracks without modification. The wire backing holds media shape under normal system airflow, reducing the risk of collapse or bypass that can occur with lighter, unbacked media.

This filter is suited for residential HVAC applications including gas furnaces, heat pumps, and central air conditioning systems with 1-inch filter housings. It is sold in a case of 12 units, making it practical for service contractors managing multiple accounts or homeowners stocking an annual supply. A 90-day replacement interval applies under typical residential occupancy and system runtime conditions. Higher particulate loads from pets, construction, or high-traffic environments may shorten that interval.

Compatibility

Designed as an OEM-style replacement for residential furnace and air handler systems requiring a 1-inch pleated filter measuring 18 inches x 18 inches x 1 inch with a MERV 8 rating.

Installation Notes

Installation is typically performed by HVAC technicians or qualified service personnel. Power down the furnace or air handler at the disconnect or thermostat before opening the filter compartment. Confirm airflow direction arrows on the filter frame align with the system airflow direction before seating the filter. Inspect the filter rack for gaps or bypass points after installation to ensure all air passes through the media.
