Resideo 203373/u Electronic Air Cleaner Prefilter 20x20 2 Pack

Product Description

The RESIDEO 203373/u is a 2-pack of 20 x 20 inch electronic air cleaner prefilters designed to capture larger airborne particles before they reach the main collection cells in whole-home electronic air cleaners. Functioning as the first stage of filtration, these prefilters extend the service life of the primary electronic cells by intercepting lint, hair, and coarse debris. They are a direct OEM-style replacement and are suited for installation by licensed HVAC technicians performing routine maintenance on residential whole-home air cleaning systems.

These prefilters are rated for use in residential electronic air cleaner systems. They are commonly installed during scheduled maintenance intervals when the electronic air cleaner cells and prefilters are removed, cleaned, and inspected. Compatible input data confirms fitment with Honeywell F300 and Honeywell F50A, F50B, F50E, and F50F electronic air cleaner units. Each pack includes 2 prefilters, allowing a complete replacement at a single service call.

Installation Notes

Installation is performed by a licensed HVAC technician. Before servicing the electronic air cleaner, shut off power to the unit at the disconnect or breaker to eliminate shock hazard from the high-voltage ionizing cells. Remove the existing prefilters, inspect the cabinet and collection cells, install the new prefilters in the correct orientation per the unit access door markings, and restore power only after the cabinet is fully closed and latched.
