  • Ideal for all brands of tankless and tank-type water heaters
  • Ensures optimal performance and efficiency
  • Maintains water pressure and flow rates
  • Prevents pre-mature heating element / heat exchanger failure

  • Simple operation with no day-to-day maintenance - just replace the filter cartridge every 2 years!
  • No salt, no chemical regeneration, and no brine discharge!
  • No backwash - save thousands of gallons of water per year compared to a traditional water softener
  • When compared to polyphosphate (Siliphos) filters, it is more environmentally friendly and displays superior performance
  • Does not add any chemicals to the water or change its taste, smell, or feel


Hard water minerals (primarily calcium and magnesium) rob your water heater of its energy efficiency by building up on its heating elements and heat exchanger surfaces. They effectively provide a layer of insulation between the heating surface and the water, thereby reducing heat transfer and putting extra stress on the heating element. Over time, the accumulation of minerals will also reduce water flow (particularly in tankless water heaters) and will lead to "hot spots". These "hot spots" cause premature failure of the heat exchanger which results in costly repairs not covered under manufacturer warranties.

ecoTAC Protector Series filters will provide benefits where the hardness of the water exceeds 7 grains per gallon or 120 ppm (mg/l), and is strongly recommended where the hardness exceeds 12 grains per gallon or 200 ppm (mg/l).

These pictures show water heating elements on a hard water source. Note the significant mineral build-up
on the element with the untreated water vs. the element protected by TAC treatment:
