White-Rodgers F825-0357 Prefilter

The White-Rodgers F825-0357 Prefilter is a critical component for maintaining the efficiency of electronic air cleaners. Specifically designed for high-performance filtration systems, this aluminum mesh filter fits White-Rodgers CSC1000 and 10C26E-410 models, as well as select Kenmore air purifiers. Measuring approximately 21 x 20 1/4 x 3/16 inches, this prefilter features a durable 1/8-inch flat aluminum frame engineered to withstand the rigors of heavy-duty HVAC applications. As a veteran technician knows, the primary function of this replacement pre-filter is to capture large particulate matter like hair and lint before it reaches the ionizing wires and collecting cells. This prevents premature loading of the electronic cells, ensuring optimal arcing and steady airflow across the 1000 CFM system. Maintaining a clean washable prefilter is essential for preventing static pressure buildup and protecting the internal power pack from unnecessary strain. Whether you are servicing a residential furnace or a commercial air handler, these genuine HVAC filtration parts ensure a precise fit and reliable system restoration.

• Optimized Airflow: Precision-woven aluminum mesh maintains high 1000 CFM capacity while trapping large debris.
• Washable Design: Durable aluminum construction allows for repeated cleaning with approved detergents like CalClean.
• Precise Compatibility: Direct OEM replacement for White-Rodgers, Emerson, and Electro-Air models including the CSC1000.
• System Protection: Extends the service interval for electronic collection cells by pre-screening hair, lint, and large dust.
• Rugged Construction: Rigid 1/8-inch aluminum frame prevents bypass and ensures the filter remains seated in the cabinet tracks.

How often should the F825-0357 prefilter be cleaned?
In most standard residential environments, the prefilter should be inspected and washed every 30 to 60 days. High-occupancy areas or homes with pets may require more frequent maintenance to prevent airflow restriction.

Can I use high-pressure water to clean this aluminum mesh?
No. To avoid flattening the woven foil or damaging the mesh structure, it is recommended to soak the prefilter in a wash tub with a mild degreaser. High-pressure sprayers can compromise the filtration efficiency.

Does my unit require one or two prefilters?
Certain large-capacity White-Rodgers models utilize a split-bank design requiring two prefilters. Always verify your specific cabinet size and model number (such as the CSC1000 or 10C26E-410) before ordering.
