Product information

Description

Water softening filter element compatible with 5-inch standard in-line housings, designed to reduce water hardness and thus decrease limescale buildup in plumbing, fittings and household appliances. The USTM ST 5 inch (model 4302000) cartridge is suitable for use in throughput water treatment systems and can be installed as a replacement element in many manufacturers' filters.

Advantages

The cartridge uses an acid ion-exchange layer inside to lower hardness during water flow, providing up to 1000 liters or 6 months of service life under recommended conditions. Its standard 5" × 2.5" dimensions allow cross-compatibility with other 5-inch filter housings and the maximum effective flow rate is 4 l/min for sustained softening performance.

Suitable for

Point-of-use under-sink softening filters (e.g., FS2/FS3 style)
5-inch standard in-line filter housings
Household and light-commercial applications for scale control
