Pro-source PRO10485 Pleated Air Filter Merv 10 18x18x1

Product Description

The PRO-SOURCE PRO10485 is a MERV 10 pleated air filter designed for residential and light commercial HVAC systems. It measures 18 x 18 x 1 inches nominal, with actual dimensions of 17-3/4 x 17-3/4 x 3/4 inches, and delivers 55% particle capture efficiency. The wire-backed pleated synthetic media holds its shape under airflow, resisting collapse at velocities up to 300 feet per minute. The rigid paperboard frame provides a consistent seal in the filter slot. Licensed HVAC technicians and service contractors install this filter as part of routine preventive maintenance or equipment commissioning on air handlers and forced-air furnaces.

This filter fits standard 18 x 18 x 1 inch filter slots found across a wide range of residential and light commercial air handling units, furnaces, and fan coil systems. Rated airflow capacity is 850 CFM with an initial resistance of 0.20 inches water gauge at 300 FPM. It is rated for use in systems with supply air temperatures up to 200 degrees F. The filter is listed for use with any unit that accepts an 18 x 18 x 1 inch filter, making it a versatile stock item for service fleets.

Installation Notes

Installation should be performed by a qualified HVAC technician following equipment manufacturer guidelines and applicable local codes. Always power down the air handler or furnace at the disconnect before removing or installing filters. Confirm airflow direction arrows on the filter frame align with system airflow before closing the access panel. Inspect the filter slot and frame seal contact surfaces to ensure no bypass gaps are present after installation.
