White-Rodgers F825-0261 Prefilter

The White-Rodgers F825-0261 Prefilter is a critical primary filtration component engineered for use in Electro-Air Thru-The-Wall (TTW) series electronic air cleaners. Specifically designed for 1400 CFM configurations, including models TTW1400 and 14C13T-410, this aluminum mesh filter serves as the first line of defense in your indoor air quality system. It effectively traps high-mass particulates such as large dust particles, hair, and lint before they can bridge the high-voltage ionizing wires or load the collecting cells. Maintaining these HVAC air cleaner parts is essential for preventing nuisance arcing and preserving the electrolytic efficiency of the primary cells.

Constructed with a rugged aluminum frame and multi-layered expanded aluminum mesh, the F825-0261 measures approximately 20-1/2" x 22-1/4" x 3/8". This washable pre-filter is built for field serviceability; contractors can restore performance by soaking the assembly in a mild detergent solution, avoiding high-pressure spray that might flatten the woven foil. By ensuring a consistent 1400 CFM airflow rating and keeping the ionizing section clear of heavy debris, this OEM replacement prefilter maintains the operational integrity of Emerson and White-Rodgers residential filtration units.

• Enhanced Cell Longevity: Captures large-scale contaminants to prevent premature loading of the electronic collecting cells.
• Optimized System Airflow: Precision-engineered for 1400 CFM systems, ensuring minimal pressure drop across the media.
• Durable Construction: Features a corrosion-resistant aluminum frame and mesh suitable for repeated wash cycles.
• Reduced Maintenance: Minimizes the frequency of manual cell cleaning by filtering out fibrous debris at the intake.
• Direct Fit Compatibility: Seamlessly slides into the pre-filter tracks of TTW1400 and 14C13T-410 air cleaners.

• How do I clean the White-Rodgers F825-0261? For best results, soak the mesh screen in warm water with a low-sudsing detergent for 20-30 minutes. Rinse thoroughly and allow it to drip dry completely before re-installation to avoid electrical shorts.
• Is this compatible with the TTW2000? No, the TTW2000 typically requires the larger F825-0262 pre-filter. Always verify the physical dimensions of your existing frame before ordering.
• When should the pre-filter be replaced instead of washed? Replace the assembly if the aluminum weave is physically damaged, flattened, or if the frame is warped, as this can lead to bypass and reduced filtration efficiency.
