FHPRA-R is a replaceable polyphosphate medium for FHPRA2 washing machine filters, designed to protect washing machines and dishwashers from limescale buildup. It helps reduce the accumulation of so-called boiler scale on drums and heating elements, which can decrease energy consumption and extend the lifespan of appliances. It increases detergent efficiency by up to 30%. Packaging 250 g (3 exchanges). Not for use with drinking water.
FHPRA-R is a replaceable polyphosphate media for a washer-dishwasher filter, designed for use in FHPRA2 washing machine filters. This filter cartridge helps protect the washing machine and dishwasher from limescale buildup on heating elements, drums, and other working components, while also improving detergent performance by up to 30%. It is a practical solution supporting water treatment for household appliances and everyday utility water filtration systems. The product is not intended for drinking water.

FHPRA-R has been developed as a replaceable media for FHPRA2 washing machine filters. Its purpose is to limit scale deposits on the components of household appliances that are in constant contact with water during operation.
Limescale deposits forming on heating elements, drums, and other internal components of appliances can accelerate wear and increase energy consumption. Regular use of the appropriate media helps reduce this problem and supports the long-term efficiency of the appliances.
The media contains polyphosphate crystals. Their action consists in converting phosphate contained in the water into calcium phosphate, which prevents so-called boiler scale from settling on household appliance components.
This is an important solution wherever hard water may negatively affect the operation of household appliances. Reducing deposits on components matters not only for protecting the appliance itself, but also for its operating efficiency.
Unlike ion exchange resin, polyphosphate does not reduce water hardness. Its role is to prevent the formation of deposits, not to soften water in the traditional sense.
FHPRA-R is a product intended to protect washing machines and dishwashers operating with water that causes limescale buildup. It works well as a consumable element of a filter installed before a household appliance, where the goal is to limit deposits on working components.
It is not a drinking water filter or a cartridge for food-related applications. The product has been designed for technical applications related to the protection of household equipment.
Do not use for treating or filtering drinking water. Calcium phosphate is not assimilated by the human body, therefore polyphosphate cartridges and filters must not be used for water intended for consumption.
The product is a replaceable material for a washer-dishwasher filter compatible with the FHPRA2 model. The package contains 250 g of media, which is enough for 3 replacements.
Regular replacement of the media helps maintain effective protection of appliances against limescale buildup and ensures proper filter operation in the water supply system feeding the washing machine or dishwasher.

Yes, the FHPRA-R media is intended for use in FHPRA2 washing machine filters.
No. Polyphosphate, unlike ion exchange resin, does not reduce water hardness. Its purpose is to limit limescale buildup on household appliance components.
Polyphosphate crystals cause phosphate contained in the water to be converted into calcium phosphate. As a result, boiler scale does not settle on household appliance components.
No. Polyphosphate cartridges and filters must not be used for treating or filtering drinking water.
The package contains 250 g of polyphosphate media.
One package is enough for 3 replacements.
Yes, FHPRA-R increases detergent efficiency by up to 30%, which can support more effective washing and dishwashing in installations exposed to limescale buildup.
