Whole-House Specialty Water Treatment for Specific Problems

Some water problems need targeted treatment at the whole-house level. If you have iron staining, a sulfur smell, or high chlorine throughout your home, a specialty filter addresses these before water reaches any fixture.

Beyond Softening

When a water softener alone isn't enough

A water softener removes calcium and magnesium, the minerals responsible for hard water. That solves a lot of problems in most Columbus homes. But if your water also contains iron, hydrogen sulfide (the source of a rotten egg odor), high chlorine levels, or sediment, those issues need their own treatment.

Specialty treatment systems are installed at the point where water enters your home. They address a specific contaminant or condition before the water continues to your softener, your fixtures, or your drinking water system. Getting the order and type of treatment right matters: feeding untreated iron into a water softener, for example, will foul the resin and cut years off the softener's life.

This is exactly what a free water analysis from Cardinal Water Solutions identifies. We test your water on-site, map out what's in it, and design a treatment sequence that addresses your specific problems in the right order.

Specialty Systems

Kinetico specialty treatment options

Each system targets a different problem. Many homes need more than one.

Well Water Kinetico Iron and Sulfur Filter

Iron & Sulfur Filter

For homes with well water or iron staining

If you see orange or rust-colored stains on your toilets, sinks, or laundry, iron is the cause. If you detect a rotten egg smell, hydrogen sulfide is the culprit. Kinetico's iron and sulfur filter uses a backwashing media bed to remove ferrous iron (dissolved), ferric iron (particulate), hydrogen sulfide, and manganese. Non-electric operation means no timers, no circuit boards, and nothing to fail during a power outage.

  • Removes ferrous and ferric iron
  • Eliminates hydrogen sulfide odor
  • Removes manganese staining
City Water Kinetico Whole-House Carbon Dechlorination Filter

Whole-House Carbon Filter

Chlorine and chloramine reduction for city water

Columbus city water is treated with chlorine or chloramines. At the concentrations used for disinfection, these compounds affect taste and odor. Over time, chlorinated water can also irritate skin and hair, degrade rubber seals and gaskets, and shorten the life of your water softener's resin bed. A whole-house carbon filter removes chlorine and chloramines from every tap in your home before they reach any fixture or appliance.

  • Whole-house chlorine and chloramine removal
  • Protects softener resin from chlorine degradation
  • Better water for skin, hair, and laundry
First Stage Kinetico Whole-House Sediment Filter

Sediment Filter

First-stage protection from particles and grit

Sand, grit, rust particles, and other suspended solids in well water or older city infrastructure can damage downstream equipment and reduce water clarity. A sediment filter is typically installed as the first stage of treatment, protecting your softener, specialty filters, and fixtures from wear. For homes with well water or older service lines, a sediment filter is almost always part of the recommended treatment train.

  • Removes sand, grit, and rust particles
  • Protects downstream equipment
  • Essential for most well water applications
System Design

How specialty treatment fits into your water system

Specialty filters always go upstream of a water softener, and a drinking water system goes at the end. The order matters, and we get it right.

Why order matters

Iron and manganese will foul a softener's resin bed if not removed first. A sediment filter upstream of a specialty media filter extends the media's life. Getting the sequence wrong means replacing expensive equipment prematurely.

Not every home needs every stage

Columbus city water homes typically do not have iron problems. Well water homes often do not have chlorine problems. Your free water analysis determines which stages your specific water actually requires.

Well Water Safety

Protecting against bacteria on well water

Private wells are not regulated by the EPA. Testing and disinfection are the responsibility of the homeowner. Cardinal Water Solutions helps Central Ohio well owners understand and address bacterial risk.

Ultraviolet (UV) Disinfection

UV disinfection exposes water to a specific wavelength of ultraviolet light that destroys the DNA of bacteria, viruses, and other microorganisms. This renders them unable to reproduce or cause infection. UV is a chemical-free process: it does not add anything to the water and does not affect taste or odor. It is highly effective and is the preferred disinfection method when the biological risk is the primary concern and the water is otherwise clear.

UV works best on pre-filtered, low-turbidity water. For that reason, a sediment filter is typically installed upstream of a UV unit to ensure consistent disinfection performance.

Chemical Disinfection

For wells with ongoing bacterial contamination, chemical injection systems deliver a metered dose of disinfectant such as chlorine or hydrogen peroxide into the water supply. These systems are appropriate when UV alone may not provide sufficient contact time, or when the water has high iron or organic content that can shield microorganisms from UV light.

Chemical disinfection systems require a dechlorination stage downstream to remove residual disinfectant before water enters the home. Cardinal Water Solutions designs the complete sequence and tests the finished water to confirm results.

Ohio recommends that private well owners test their water at least annually for coliform bacteria. If you have never tested your well or have not tested it recently, contact us. We include a bacterial screening as part of our free water analysis for well water homes.

Common Questions

Specialty treatment FAQs

It depends entirely on what is in your water. A water softener is designed to remove hardness minerals, calcium and magnesium, and nothing else. If your water also contains iron, hydrogen sulfide, high chlorine levels, or sediment, those issues persist after softening. In fact, iron in softener influent will gradually foul the resin, reducing the softener's capacity and eventually requiring early replacement or regeneration with iron cleaner. A free water analysis identifies what your water actually contains so you only install what you need.
Hydrogen sulfide (H2S) is a gas that dissolves in water and produces the characteristic rotten egg smell. It occurs naturally in some groundwater, particularly in areas with organic material and certain rock formations. At the low concentrations typically found in private wells, hydrogen sulfide is not acutely dangerous to health, but it makes water unpleasant to use and smell, and it can corrode metal pipes and fixtures over time. At higher concentrations, it can become a health concern. Kinetico's iron and sulfur media filters remove hydrogen sulfide effectively, and the treatment is non-chemical.
Yes. Municipal water is treated before it leaves the plant, but the distribution pipes and the service line running to your home may be older cast iron or steel. As those pipes corrode, rust particles and dissolved iron can enter your water. If you see orange staining in your toilets or sinks and you are on city water, aging pipes are the most likely cause. A water analysis will confirm whether iron is present and at what level, so we can size and select the right filter.
Most Kinetico specialty filters, including iron and sulfur media filters, are non-electric. They use the kinetic energy of flowing water to operate and backwash, consistent with Kinetico's design philosophy across the product line. UV disinfection units do require electricity, as they need a powered lamp to generate the disinfecting light. Chemical injection systems also require a small pump. We will specify which equipment needs power and where, and handle the installation of all necessary electrical connections.
You get a free water analysis from Cardinal Water Solutions. Our technician visits your home, tests your water on-site for hardness, iron, pH, sulfur, chlorine, and other indicators, and reviews the results with you. For well water, we can also coordinate laboratory testing for bacteria, nitrates, and other parameters that require a lab analysis. Based on the results, we recommend only the treatment your water actually needs, nothing more. Schedule yours at free-water-analysis.html.
