Diversitech tuv-rfm-4-1820 Uv Reactive Media Filter 18x20x4

Product Description

The DIVERSITECH tuv-rfm-4-1820 is a replacement UV-reactive media filter designed for use with the Fresh-Aire UV Purity whole-house air purification system. Measuring 18 inches x 20 inches x 4 inches, this filter media works in conjunction with UV light technology to capture and neutralize airborne contaminants as air passes through the system. It is engineered as a direct OEM-style replacement, ensuring the Purity system continues to operate at its intended filtration level. HVAC technicians and service professionals install this filter during routine maintenance intervals to restore system performance.

This UV-reactive media filter is intended for residential whole-house applications where the Fresh-Aire UV Purity system is installed in the main return air duct or air handler. It is suited for standard forced-air HVAC configurations and is designed to replace the existing media at the manufacturer-recommended service interval. The 4-inch depth provides a substantial media bed, supporting effective particle capture across the entire filter face.
