Listings show filtration ratings generally ranging from about 20 microns up to 50 microns across available 50 sq ft cartridges.

Dimensions vary by model: listed lengths/heights run roughly from about 8.19 inches up to 20 inches, and outer diameters range approximately from 4.93 inches to 10 inches.

Connection and hole specifications vary by listing. Examples shown include a top hole of about 5.9375 inches and a bottom hole of about 6 inches; threaded 2‑MPT top/bottom connections; top/bottom holes around 2.12 inches; and end cap inside diameters near 2‑1/8 inches. Exact sizes differ by model, so check the listing or measure your existing filter to confirm fit.

Listings highlight chlorine‑resistant or durable plastic end caps, double‑reinforced or sturdy open‑flow cores, robust pleat materials, and max‑flow cores designed to withstand pressure and repeated cleanings.

Listings provide part‑number cross references and repeated fit guidance, and they advise measuring your current filter’s dimensions and hole sizes to confirm a match before buying.

Listings call out sharp, uniform pleat folds and open‑flow or max‑flow cores to maximize water flow and minimize pressure loss. They also note that durable end caps and reinforced cores help reduce pump stress during operation and repeated cleanings.
