Why it matters
The Cryspool cryspool 04075 Spa Filter Cartridge is a replacement spa and hot tub filter cartridge that its listing says replaces c-4950, prb50-in, with 50 sq ft of media.
3 other cartridges we cover name at least one of the same part numbers: TOREAD TRF-4950 Spa Filter Cartridge, AmiBron A-4950-2 Spa Filter Cartridge, X psblty PRB50-IN Spa Filter Cartridge. Compare filter area and pack size before choosing.
Match the part number on your old cartridge or filter housing first; if it has worn off, measure length, outside diameter and both center holes. A cartridge that is close but not exact can let dirty water bypass its seals.
The listing gives dimensions of 13.97 x 10 x 5.5 inches and a weight of 1.6 ounces.
