A: If your system takes a screw-in PWW50P3 style cartridge (approx. 15.2cm diameter, 1.5 inch SAE coarse thread) - or any of the part numbers in the compatibility list above - this cartridge will suit. Check the thread on your existing cartridge: the SAE thread has wide, coarse spirals. If unsure, send us a photo and we'll confirm fit. Q: Is this the same as a PWW50P4? A: No - the PWW50P3 uses a coarse SAE thread, while the PWW50P4 uses a fine thread. They are not interchangeable, so check your thread type before ordering. Q: Can I wash and reuse the cartridge? A: Yes - rinsing between changes extends its life. Replace on schedule (or when visibly dirty) to keep water quality and flow consistent. Q: What if my system uses a drop-in cartridge instead? A: For drop-in (non-threaded) systems, see our 25 micron PLFPRB25-IN and 50 micron PLFPRB50-IN cartridges.
