Dad Approved Tac-4520 20" X 4.5" Anti-scale Replacement Cartridge Kit For Scalenet/oneflow/h2flow Holiday Cheer Edition [KPaB2Td6]

Calcium creates scale in pipes, on appliances and heating elements. This leads to higher heating and energy costs and expensive repairs to appliances, such as tankless water heaters, washing machines, and dishwashers.

The TAC Salt Free Water Conditioning System's Template Assisted Crystallization, or TAC process transforms Calcium ions into Calcium crystals, which are stable and cannot attach to pipes, surfaces, hardware or heat exchanger components. The crystals are so small they are easily rinsed away by the water flow.

This new media technology is also sold and marketed under a variety of other brand names like Next Scale Stop, Filtersorb as well as Watts ScaleNet, Noritz H2Flow.

Kit Includes:
  • (1) 4-1/2" x 20" Reusable Cartridge
  • (1 Liter) 75 gpg 4 gpm TAC Media

TAC-4520 Anti-Scale Replacement Filter Benefits:
  • Scale is virtually eliminated
  • Aids in removing existing scale
  • No costly repairs to appliances due to scale
  • No salt
  • Saves water
  • No electricity
  • Replace cartridge every 2 years
Hard water is made up of calcium ions (Ca2+), magnesium ions (Mg2+), and bicarbonate ions (HCO3-). This anti-scale filter uses a template assisted crystallization process, or TAC process which transforms these dissolved ions into non-charged, neutral chemical bonds, of calcium and magnesium crystals. These microscopic crystals of scale quickly form in treated water and cannot attach to pipes or any surface, and are rinsed away downstream in a colloidal suspension by the water flow. These crystals are heat resistant and are unable to revert to it's dissolved state.

Note: For well water applications, please contact our technical support staff.
