The Pentair Water Softener Alternative with NaturSoft Salt-Free Technology is our premium whole house salt-free water conditioning solution. As a salt-free water softening alternative, it gives you the conditioned water and hassle-free maintenance you desire.

  • A no-salt solution can save you time and money
  • Uses template-assisted crystallization (TAC) to convert dissolved hardness ions into insoluble crystals that will not form scale on surfaces while retaining beneficial minerals in your water
  • Two unique models to choose from to meet the demand of your home based on home size (or number of bathrooms)

Benefits of the Water Softener Alternative with NaturSoft Salt-Free Technology

Hard water minerals – like calcium and magnesium – can wreak havoc throughout your home. Scale buildup in your piping and appliances can reduce their effectiveness, cause dingy and stiff laundry, require expensive fabric softeners, stain your plumbing, and cause spotting on your dishware. Our Water Softener Alternative with NaturSoft Salt-Free Technology can give you the conditioned water you desire without the slippery feeling. For the best results, Pentair recommends that you test your water hardness level using the Pentair 16-Point Rapid Water Test before purchasing a salt-free softener alternative, to be sure the NaturSoft technology is right for your home water. Other features include:

  • No electricity required to operate
  • Produces zero water waste
  • Comes with a 5 micron prefilter to reduce sediment and debris from your water
  • Durable stainless steel design
  • DVGW certified to be 99.6% effective at reducing hard water effects

How it works

cut out image of system, 1 on prefilter, 2 toward top of filter tank and 3 close up shot of hard minerals being dissolved


Water enters the prefilter where particulates larger than 5 microns in size will be reduced. This filter is placed before (prefilter) or after (postfilter) the conditioning process.

Calcium Carbonate Crystal

The media contains nucleation sites that initiate formation of calcium and magnesium crystals on the media reducing the dissolved “hard” minerals which reduces the hardness from the water and, as a result, the scaling potential. The movement of water and friction among the media granules rubbing against each other cause fragments of the newly grown crystal structures to be fragmented off the media and released into the passing water.

Movement and Friction

Those free flowing calcium carbonate crystals continue to travel through the plumbing system as suspended particles which buffer the effects of hard water scaling. This effect is most beneficial when you get to your water heater. When heated the water’s scale potential increases and the seed crystals absorb the additional calcium that would otherwise form scale.
