CellarPro 3200S/4200S Replacement Air Filter 2-Pack (P/N 1121). Poly-coated fiberglass air filters trap more dust particles than regular fiberglass filters. The frame is made of fiberboard and has two tin-plated steel grills (one bonded to each side) as well as sealed corners to prevent dust leakage. CellarPro 3200S/4200S filters are marked with size and airflow direction. Actual length and width are 3/8″ less than the trade size shown. Filters meet UL Class 2 flame retardance requirements. The maximum temperature is 180 degrees. Sold in a pack of two filters.

The filters fit CellarPro 3200 and 4200 wine cooling units, including the duct hood, and are for interior use only.
