Using this Poly Triple Action Hard Water Filter means cleaner, purer and much tastier drinking water. You get three awesome products in one compact filtration system. If you are like most homeowners, you might have several filters, softeners or conditioners installed to perform several tasks including water filtration and hard water treatment/conditioning. Our Triple Action Hard Water Conditioner has all of these features built-in and actually performs three separate functions. 

First of all it has a built-in cleanable stainless steel 50 micron filter that is easily removed for service as needed.  No more needing to buy replacement water filters! Second, it uses our Hard Water Bullet which is an “Electro-Mechanical” Catalytic Process water conditioning core that breaks down the calcium hardness in the water into aragonite crystals. Aragonite is a softer form of calcium that will not build-up like untreated limescale, which will eventually damage fixtures, pipes and appliances. Aragonite will also coat the inside of pipes and tanks adding a layer of anti-corrosive protection. Third, it holds 10.5 ounces of polyphosphate crystals which will keep the aragonite and iron in suspension and helps keep spotting from occurring.

Polyphosphates have long been used in controlling hard water deposits in water systems. It is available in powder, liquid and crystal form. The polyphosphate dissolves into the water as it passes through the conditioners housing and coats the hard water minerals and aragonite making it impossible for these agents to precipitate out of the water and create limescale build up. This descaling agent ties up the hardness and keeps it in suspension.

Polyphosphates have been around many years in different applications ranging from municipal water supplies, commercial applications as well as residential applications, all with excellent success.

How It Works:

First Step:

The incoming water goes through the Hard Water Bullet scale control core to break down the calcium scale into aragonite crystals

Second Step:

The treated water goes through siliphos treatment from polyphosphate crystals.

Third Step:

The conditioned water passes through the stainless steel 50 micron screen filter. 


The Final Result:

Even though the treated calcium has been converted into aragonite, it is kept in suspension because of the addition of the poly-phosphates. And you maintain the health benefits of having the minerals left in the water. You will enjoy clean and naturally treated water without using salt to treat your water.


It is recommended that every six months to check the level of polyphosphate crystals, clean the filter and Hard Water Bullet core. This may change for your particular application and depends on water usage. Please review the service video at the bottom of this page

The Poly Triple Action Hard Water Filter should be installed vertically allowing the drain valve to be positioned pointing down, which allows for easy draining of the filters housing, and to relieve pressure on the filters housing for servicing. The water inlet and outlet are both  1" pipe threads and can be bushed down to 3/4" if nessasary. Use the included BST-NPT thread adapters. Install this Hard Water Filter AFTER your pumps pressure tank and do not allow it to freeze.


Every 10-12 months, simply un-screw the housing bottom and check the level of poly crystals, check the hard water bullet for corrosion, and clean the filter if needed. Please see the downloadable service sheet on the top of this page.
