The scale is calcium and magnesium deposits that form on household plumbing fixtures (showerheads, faucet, and pipes) and appliances like a dishwashing machine, clothes washer, heaters (gas, electric & tankless style), and boilers.

The scale build-up can shorten the life of household appliances, cause the plumbing fixtures to clog leading to water pressure loss, increase energy usage leading to high utility bills and improve the efficiency 

The filter is easy to maintain compared to traditional water softener because:

  • It requires no salt to operate
  • Less water wastage 
  • No backwashing or regeneration required
  • Requires less space
  • No electricity is required

The only maintenance required is a change of filter but this depends on the water quality.

What does a polyphosphate filter do?

Polyphosphate filter is not a water softener. It does not remove hard water minerals (calcium and magnesium) but makes them inactive such that do not form scale on your plumbing and appliances.

Most anti-scale water filter uses Template Assisted Crystallization (TAC) technology. The TAC technology attracts hard water minerals and transforms them into inactive microscopic crystal particles or crystalize so as not to form scale on household plumbing and appliances.

The crystals stay suspended in the water and are passed to the drain

It keeps healthy minerals in your water not like traditional water softener that remove hard water minerals
