WFST UST-M is a compact washing machine and dishwasher filter installed on the cold water inlet to a washing machine or dishwasher. This water filter with soluble polyphosphate media supports water treatment in the appliance supply system, limits limescale buildup, helps gradually reduce existing deposits, and stabilizes iron compounds, reducing the risk of rusty stains on fittings. Thanks to its universal 3/4" connection and compact dimensions, it is a practical part of a home water filtration system for household appliances.

WFST UST-M is designed to operate on the cold water inlet. Its purpose is to protect the components of washing machines and dishwashers from the negative effects of limescale and deposits formed during appliance operation.
The soluble polyphosphate media used in the filter limits the formation of new limescale deposits while also supporting the gradual dissolution of deposits already present in the system. This solution helps keep fittings and components that come into contact with water in better working condition.
The polyphosphate used in the WFST UST-M model works in two ways, effectively supporting the protection of the installation and household appliances:
An additional benefit is the stabilization of iron compounds, which helps reduce the formation of rusty stains on fittings. This is especially important where the supply water may promote the buildup of deposits and discoloration.
The small size of the filter and its universal connection mean that the WFST UST-M model can be used with most washing machines and dishwashers available on the market. The compact housing makes installation easier where space around the water connection is limited.
