White-Rodgers F825-0337 Aluminum Prefilter

The White-Rodgers F825-0337 Aluminum Prefilter is a high-duty, permanent mesh solution designed for trade professionals maintaining high-efficiency electronic air cleaners. Engineered for specific Emerson and White-Rodgers units, including the SST1600-100, UST-16, and 16C21M-4101 models, this washable aluminum filter captures large particulate matter before it reaches the electronic cells. This critical first-stage filtration prevents excessive loading and nuisance arcing, ensuring the unit operates at peak ionizing efficiency. With nominal dimensions of 10-1/2" x 20-1/4" x 5/16" (actual size approximately 10-7/16" x 20-5/16"), it provides a secure fit within the filter rack, maintaining the structural integrity of the air path. For technicians, using an OEM replacement prefilter like the F825-0337 is the industry standard for sustaining optimal airflow and protecting the more sensitive internal components of the HVAC system from heavy dust and debris buildup.

Key Benefits

• Compatible with Emerson 16 and White-Rodgers SST1600 electronic air cleaners.
• Constructed from corrosion-resistant aluminum mesh for long-term durability in varied environments.
• Permanent, washable design allows for repeated field maintenance without professional replacement modules.
• Reduces primary filter load, extending the service interval for electronic collector cells.
• Maintains static pressure integrity by effectively trapping large debris without restricting airflow.

Common Questions

Does this prefilter require two units for installation?
Many 16-inch models, such as the SST1600, require two F825-0337 prefilters for a complete set. Technicians should verify the total quantity needed based on the specific cabinet width during the job-site inspection.

Is the F825-0337 a direct replacement for the 16C21M-4101?
Yes, this aluminum mesh filter is the designated replacement part for the 16C21M-4101 and the UST-16 series, ensuring a precise fit without requiring field modifications.

What is the best way to clean this aluminum mesh?
Contractors should use a mild detergent and warm water to break down grease and dust. Avoid caustic chemicals that can degrade the aluminum framing or mesh structure.
