Aquafilter 10 inch polyphosphate water softener against limescale and corrosion. 1/2″, 6 bar, cold water only.

The Aquafilter 10 inch polyphosphate water softener is a 10″ filter with a replaceable polyphosphate cartridge that protects household and heating systems from limescale and corrosion. According to the seller, polyphosphate crystals dissolve slowly in the water, reduce calcium and magnesium deposits on heaters and pipe walls and form a protective film on surfaces by dosing in minimal amounts. It is intended for washing machines, dishwashers, flow-through heaters, boilers and fittings. It needs no electricity. It is for cold water only and is not suitable for treating drinking water or food-preparation water.

The Aquafilter 10 inch polyphosphate water softener doses polyphosphates into the water in minimal amounts as the crystals dissolve. The seller states this reduces limescale on heating surfaces and pipes and brings lower energy use and fewer pipe blockages; the page gives no measurements. General information (not from the page): polyphosphate usually does not remove water hardness but limits the build-up of limescale, so "softener" in the product name is a trade term rather than true softening. Note that the page recommends cold water only and a maximum of 45 °C, even though it also mentions protecting heaters; fit the filter on the cold-water line before the appliance.

The description refers to a polyphosphate cartridge as part of the product, but the page does not explicitly confirm that both housing and cartridge are supplied, so please check with us before ordering. The replacement cartridge, ANTI-SCALE FCPRA-10, is listed on its own page; no price is shown on this page. A 10″ cartridge for removing limescale, sand and mud is also available.
