These filters are the perfect option for those who don’t want to deal with the maintenance issues posed by water softeners. They don’t require electricity, they function without salt, and don’t have backwash systems or brine tanks. They are just like regular filters, but come with scale inhibiting features. In terms of filter media, they usually contain granular activated carbon in combination with phosphate, or they can contain pyrolox or water softening resin. Depending on the type of filter media contained by these filters, they either remove manganese and iron, or prevent limescale deposits by transforming calcium ions into calcium crystals.
While the quality of your tap water largely influences the limescale control and reduction capabilities of these filters, the efficiency of some modelsis on par with the efficiency of traditional water softener systems. Buy Watts, Pentek and Doulton scale reduction filters and enjoy the benefits of soft water without the hassle of installing and maintaining a traditional water softener system.
