The scale is calcium and magnesium deposits that form on household plumbing fixtures (showerheads, faucets, and pipes) and appliances like dishwashing machines, clothes washers, heaters (gas, electric, and tankless style), and boilers.

Scale build-up can reduce the life of household appliances, cause plumbing fixtures to clog, resulting in a loss of water pressure, increase energy consumption, result in higher utility bills, and improve efficiency.

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

  • It requires no salt to operate.
  • Less water wastage.
  • No backwashing or regeneration is 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?

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

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

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

Unlike traditional water softeners, which remove healthy minerals from your water, it keeps them in.
