Price range: $824.00 through $1,360.00

(7 customer reviews)

NaturalSof is a low-maintenance scale reduction system designed to help minimize hard water scale buildup throughout your plumbing system. Using catalytic conversion technology, NaturalSof alters the structure of hardness minerals so they are less likely to adhere to pipes, fixtures, water heaters, and appliances.

Unlike salt-based water softeners, NaturalSof does not remove minerals from the water and requires no salt, electricity, regeneration cycles, or replacement media.

NS05 and NS6 are currently in stock and ship within 1 week. NS1 will be restocked soon—please contact us for the latest availability and estimated timeline.

Key Details
  • Reduces Scale Buildup: Helps prevent hardness minerals from forming stubborn scale deposits on plumbing, fixtures, and appliances.
  • Chemical-Free Operation: No salt, chemicals, electricity, regeneration cycles, or wastewater discharge.
  • Low Maintenance: No replacement media or routine servicing required.
  • No Mineral Removal: Unlike traditional softeners, NaturalSof does not remove hardness minerals from the water.
  • NSF Certified: Certified to NSF/ANSI 61 and NSF/ANSI 372 standards for drinking water system components.
How It Works

NaturalSof uses catalytic conversion technology to alter the structure of hardness minerals such as calcium and magnesium. Rather than removing these minerals from the water, the system encourages them to remain suspended and less likely to adhere to plumbing surfaces.

This can help reduce scale accumulation on water heaters, fixtures, appliances, and plumbing while preserving the naturally occurring minerals in the water.

Environmental Benefits

Because NaturalSof does not use salt or regeneration cycles, it produces no brine discharge and does not waste water during operation. It offers a low-maintenance approach to scale reduction while avoiding many of the environmental concerns associated with traditional salt-based softeners.

How NaturalSof Works

NaturalSof does not soften water in the traditional salt-softener sense. Instead of removing calcium and magnesium, it helps change how calcium carbonate behaves in the water.

Hard Water Enters

Hard water naturally contains dissolved minerals, especially calcium and magnesium.

Catalytic Core Activates

As water flows through the NaturalSof unit, it passes over a non-sacrificial catalytic alloy core.

Scale Changes Form

The catalytic reaction encourages calcium carbonate to form as soft, non-bonding aragonite crystals instead of hard calcite scale.

Scale Passes Through

These microscopic crystals stay suspended in the water and are carried through the system instead of bonding to surfaces.

Conditioned Water, Not Stripped Water

Traditional salt softeners remove hardness minerals and exchange them with sodium. NaturalSof takes a different approach: it does not add anything to your water and does not remove the minerals naturally present in it. The goal is to reduce hard limescale buildup while keeping the water mineral-balanced.

Where NaturalSof Helps Most

Helps Protect

  • Water heaters
  • Tankless systems
  • Faucets and fixtures
  • Showerheads
  • Appliances
  • Plumbing lines

What To Expect

NaturalSof is designed to help prevent new hard scale from bonding to surfaces. In many homes, existing scale may gradually become easier to remove over time. You may still see mineral spotting where water evaporates on glass, dishes, or fixtures, but the residue is typically easier to wipe away than untreated hard scale.

Important: NaturalSof is for limescale prevention. It is not a sediment filter, carbon filter, PFAS filter, bacteria filter, iron filter, or traditional salt softener. If your water contains iron, manganese, sulfur, heavy sediment, or other problem contaminants, additional treatment may be needed.

Choosing the Right NaturalSof

Correct sizing matters. NaturalSof effectiveness depends on flow rate through the device, so bigger is not always better.

ModelBest ForMinimum Flow RequirementMaximum Flow @ 50 PSI
NS05Point-of-use applications or hot water recirculation return loops0.5 GPM5 GPM
NS1Most homes with fewer than 5 bathrooms or fewer than 5 users1 GPM10 GPM
NS6Larger homes with 5+ bathrooms and 5+ users6 GPM16 GPM
Sizing note: Oversizing should be avoided. For most homes, NS1 is the standard choice. NS6 should only be used when the home has both larger demand and enough flow to activate treatment consistently.

NaturalSof FAQ

Is NaturalSof the same as a salt softener?

No. A salt softener removes calcium and magnesium through ion exchange and replaces them with sodium. NaturalSof does not remove those minerals. It conditions the water to help reduce hard limescale bonding.

Will my water feel slippery like softened water?

Usually no. Because NaturalSof does not remove hardness minerals, it typically does not create the slippery feel associated with traditional salt-softened water.

Will NaturalSof remove contaminants?

No. NaturalSof is for scale prevention, not contaminant filtration. For chlorine, PFAS, heavy metals, sediment, bacteria, or other contaminants, pair it with the appropriate Greenfield Water filtration system.

Will I still see spots on glass or shower doors?

You may still see mineral residue when water evaporates, especially on glass, dishes, and fixtures. The difference is that the residue is generally less bonded and easier to clean than untreated hard scale.

Does it require maintenance?

NaturalSof does not require salt, chemicals, power, magnets, or routine media replacement. Product life expectancy is listed at 10–15 years.

A Better Fit for Mineral-Balanced Homes

NaturalSof is a strong option for families who want to reduce limescale buildup without removing beneficial minerals from their water. It pairs especially well with whole-home filtration when the goal is cleaner, better-functioning water throughout the home.

Salt-Free Scale Reduction

Which Descaling Solution Is Right for Your Home?

Greenfield Water Solutions offers three distinct salt-free descaling technologies, each designed for different needs, budgets, and installation preferences.

Important note: Salt-free descalers are not traditional salt-based softeners. They do not remove calcium or magnesium from the water. Instead, they help reduce scale formation by changing how hardness minerals behave, making them less likely to bond to pipes, fixtures, heating elements, and appliances.

7 reviews for NaturalSof Catalytic Descaler | NSF Certified Scale Reduction System

  2. Louie of Arizona (store manager) –

    If you have experienced the hard water, you know it is difficult to keep the calcium scale from building up, especially on surfaces like black countertops! Before finding NaturalSof Louie in Arizona was on a rigorous maintenance schedule, battling the crusty scale with razor blades and lime away.

    Like a lot of our raving fans, Louie started out as a skeptic. Now he says, “i am a believer.”

    Of special note is his statement about having “much hotter water.” Not only are things more aesthetically pleasing on the outside, but now Louie’s water heater is cleaner and more efficient on the inside. We are glad to have the feedback…thanks Louie!

    This product is great. It has gotten rid of most of the hard water stains we were getting. My laundry is cleaner and lighter, fresh smelling. My skin is not as dry. And your price is much better than the plumbing store.

  7. Terence (verified owner) –

    I have only had this descale 1 month. It will take a while to see results. Appears to be quality product.
