Honeywell 0120301 Merv 4 Trimmable Air Filter 20x30x1

Product Description

The HONEYWELL 0120301 is a MERV 4 trimmable air filter designed to capture large airborne particles such as dust, pollen, and dirt before they reach furnace and air conditioning equipment. Measuring 20 inches x 30 inches x 1 inch, this fiberglass-style panel filter can be cut to fit non-standard or irregular openings without tools or special equipment. The washable design supports repeated use, making it a practical option for residential and light commercial systems where basic filtration is the primary goal. Licensed HVAC technicians and experienced service pros typically stock this filter for quick installations across a wide range of air handler and furnace applications.

This filter is suited for residential forced-air furnaces and split-system air conditioning units requiring a 1-inch panel filter. Its trimmable frame makes it a flexible solution when dealing with older equipment with non-standard filter slots or return-air grilles that fall between standard sizes. It is sold individually and is appropriate for applications where MERV 4 filtration meets the system design requirement.

Installation Notes

Installation is performed by a licensed HVAC technician or qualified service professional. Power down the furnace or air handler at the disconnect before replacing the filter. Confirm airflow direction markings on the filter frame align with system airflow before seating the filter. If trimming the filter to size, score and cut on a flat surface and ensure the trimmed edge seats flush against the filter rack to prevent bypass.
