Buying Guide

Match housing size to cartridge length

Choose 10" housings for standard point-of-use or retrofit setups and 20" or 20"x4.5" housings for higher capacity and less frequent cartridge changes

Check port size and thread type

Confirm inlet/outlet port dimensions (for example 1" NPT) to ensure compatibility with existing plumbing and fittings

Assess material and visibility needs

Opaque polypropylene housings resist chemicals and UV, while clear housings let you visually inspect sediment without opening the unit

Prioritize flow rate and pressure specs

Select housings rated for your household flow and well pressure; larger-diameter 4.5" options typically support higher flow and heavy sediment loads

Factor in installation and maintenance

Look for housings with brass ports, standard wrench compatibility, and easy-open designs to simplify seasonal cartridge changes and leak prevention
