Formation of scale reduces efficiency of home boiler or heater operation, eventually resulting in breakdown of the equipment with no possibility for recovery.

The Filter1 polyphosphate filter:

  • protects the equipment from scale

  • saves energy

  • increases efficiency and extends service life of boiler or heater.

Advantages of the filter:

  • Affordable price from the Ukrainian manufacturer

  • Easy and convenient refilling which can be performed with your own hands, without engaging a specialist

  • Protection from sediment.

With the filter, you will cut the expenses connected with

  • boiler or heater maintenance

  • filter maintenance

  • electric energy consumption

Boiler and heater will serve much longer.

The filter represents a transparent bulb containing crystals of polyphosphate. Flowing through the filter, the water gradually dissolves the crystals and becomes saturated with polyphosphate. The polyphosphate film covers the surface of heating elements and prevents scale formation. Thus, the heating element remains clean.   

Nylon mesh reduces the content of sediments larger than 100 micron including sand, silt, and rust.

Polyphosphate is intended for cold water used only for household (NOT drinking) purposes.

Polyphosphate must NOT be used to treat drinking water.

Polyphosphate is not completely dissolved by water, but its efficiency gradually fades. Hence, to appropriately protect the heating elements you are recommended to replace the filter every 6 months.
