35 Sq. Ft. Waterway Replacement Filter | ProAqua

This ProAqua 35 sq. ft. Waterway replacement filter has a closed top with a handle and a 1-1/2-inch female SAE threaded bottom opening.

The ProAqua part number is PA4935, and the ProAqua supplier SKU is PA40355. Pleatco PWW35L, Unicel 4CH-935 and Filbur FC-0170 are cross-references for compatible replacement filters, not the brand supplied. Manufactured by Magnum Filters, this cartridge features PVC plastic ends designed for a more rigid filter construction. Before ordering, compare your existing filter's reference number, dimensions and threaded connection with the details below to confirm the fit.

Threaded base design

The Magnum Filters base differs from the raised threaded opening used on the Unicel and Pleatco versions. Its PVC construction uses fewer threads to seat properly. Check both the cartridge measurements and the threaded connection against your current filter rather than relying on appearance alone.
