scale prevention
Combat Scale. Boost Efficiency.
Next-Scale Stop™ utilizes advanced, cutting-edge technology to deliver most of the benefits of water softeners. At the core of its performance is TAC® (Template Assisted Crystallization®), the first proven, reliable, and chemical free method for preventing scale buildup, and with zero environmental waste.
ScaleStop™ is not a water softener, ScaleStop™ protects your home's plumbing and appliances by preventing scale buildup without the use of salt or harsh chemicals. It works by transforming dissolved hardness minerals, into microscopic crystals. These crystals remain suspended in the water and are less likely to stick to surfaces, meaning they won't accumulate inside pipes, water heaters, showerheads, or on glass and fixtures. The result? Cleaner appliances, better water flow, and reduced maintenance.

What is Template Assisted Crystallization®? (TAC®)
Next-ScaleStop™ uses advanced Templated Assisted Crystallization® (TAC) technology to prevent scale buildup. This innovative process works by forming microscopic crystals of calcium carbonate (CaCo3) on the surface of specially treated polymer beads. These crystals act as templates, attracting additional hardness minerals from the water as they precipitate. Because the crystals are stable and relatively insoluble, they keep the calcium carbonate suspended in the water rather than allowing it to stick to pipes, fixtures, or appliance effectively protecting your plumbing system from scale.
TAC® Technology
Crystal Formation
The surface of small polymer beads attract scale-causing ions, creating micro-crystals that become preferential templates for other ions to build on.
Crystal Release
Once the crystals grow to certain size they continue to flow through the pipeline. The crystals in solution keep the hardness out of the water so that it can’t form scale or interfere with soap.
This process inactivates the minerals, causing them to flow right through pipes and down the drain, completely unnoticeable without specialized technology.

Scale Reducing Protection
Home Protection a with Pre-filter and Scale Reducer. The prefilter works alongside the scale reducing system to remove sediment and impurities before treating your water. This two-step process protects your plumbing and appliances from scale, and particles, ensuring cleaner, clearer water throughout your home with minimal maintenance.

What is Chloramine and why is it used in Tap Water?
Chloramine is a disinfectant commonly used in public drinking water systems. It’s created by combining chlorine -the standard disinfectant used in most municipal water-with ammonia. Unlike chlorine, chloramine is not sold in stores; it must be produced onsite at water treatment plants.
Chloramine is more chemically stable than chlorine, which means it stays in the water longer as it travels through pipes to your home. This helps ensure your tap water remains clean and safe all the way to your faucet. It also produces fewer disinfection byproducts (DBPs), which can form when chlorine reacts with organic material in water. Because of this, chloramine is becoming a preferred method for disinfecting public water supplies.
The U.S. Environmental Protection Agency (EPA) regulates the use of chloramine in drinking water. The maximum allowable level is 4 milligrams per liter (mg/l), or 4 parts per million (ppm), which is considered safe for daily use in residential homes.
Across the United States, nearly 250,000 public water systems provide water to around 90% of the population. Approximately 98% of these systems use either chlorine or chloramine as part of their water treatment process. Each year, your local water utility is required to send out a Consumer Confidence Report – also called an Annual Water Quality Report. This report details where your water comes from, how it’s treated, and what’s in it, including levels of chlorine or chloramine.
Can Chloramine be removed from Tap Water?
Just like chlorine, chloramine can be removed from household water using either whole-home or point of use carbon filtration systems. However, removing chloramine is more challenging due to its chemical stability.
Chloramine is a more stable molecule than chlorine, meaning it requires a more reactive filtration media and longer contact time to be effectively removed. While standard activate carbon-whether coconut shell or coal based is highly effective at removing chlorine, it does very little to reduce chloramine levels.
There’s a common misconception that regular activated carbon removes chloramine by stripping away the chlorine and leaving only ammonia behind. In reality, standard carbon does not break apart or neutralize chloramine molecules effectively. If your home currently uses a standard dechlorination system, it’s important to know that it likely does not reduce chloramine. To property treatment chloramine, you need a system specifically engineered for it.
Kinetico’s Chloramine Reduction System (CRS) features its proprietary media Chloraban®, which is specifically designed to reduce both chlorine and chloramine from your water supply. In fact, Kinetico CRS systems are the only residential whole-house chloramine reduction systems certified by the Water Quality Association (WQA).
