We receive a number of calls every day requesting information about Home Water Treatment Systems from people with wells, city or municipal water systems and people served by private water companies. They’re all looking for water treatment facts. We offer this as a little primer on water treatment systems.


Four Types of Water Treatment Systems

There are four main types of whole-house water treatment systems: soft water, reverse osmosis, carbon filter and KDF® filter systems.


Soft Water Treatment Systems

The soft water treatment system is both well known and misunderstood; not only by homeowners, but by the companies who sell them. With well water, a water softener is used to remove iron and soften the water. Many people selling soft water systems neglect to inform buyers that they might need a filter system along side the water softener.

This is why we require well owners to have a water test done by a major test lab like National Testing Laboratories, Ltd. (phone: 800-458-3330) before they purchase a water treatment system.

Some people feel that using a water softener is bad because the high level of sodium content. Two things you should know:

  1. An alternative to salt for softening water is Potassium Chloride. This is considered as a more environmentally-friendly alternative to introducing sodium chloride into our water systems
  2. A soft water loop is designed to bypass the kitchen sink, ice maker and exterior hose bibs. When the system is plumbed properly, the sink and hose bibs remain “hard.”

Reverse Osmosis Treatment Systems

Many people who purchase a soft water system add a reverse osmosis “RO” treatment system under their sink to remove impurities from their drinking water, making it look, smell and taste better. We offer several RO water treatment systems here.

While it is possible to make your whole house RO purified, it’s very expensive and not particularly practical. The typical whole house RO unit can waste more water than it recovers.

Carbon Filter Treatment Systems

Carbon filters use granular activated carbon (GAC) to remove certain chemicals - in particular, organic chemicals - from water. GAC filters also can be used to remove chemicals that give objectionable odors or tastes to water such as hydrogen sulfide (rotten eggs odor) or chlorine.

Many people use a PUR® or Britta® charcoal filters that can make your water look and smell good, but the filters need changing often and do not remove the impurities - such as iron and chemicals - that other water treatment systems can remove.

GAC is an effective de-chlorinating medium, but not in shower filters. Many early manufacturers thought GAC properties were directly transferrable to shower filter applications, but that’s been proven false. 

KDF® Filter Treatment System

We recommend using a system for drinking water that uses a KDF® filter. We offer one- two and three-filter systems in 10 inch and 20 inch sizes. KDF process media supplement or replaces existing technologies to dramatically extend system life, reduce heavy metals, microorganisms, scale, lower total cost, and decrease maintenance.

Hospitals, restaurants, municipal water treatment facilities and homes rely on KDF process media to safely reduce or remove chlorine, iron, hydrogen sulfide, heavy metals, volatile organic compounds, and bacteria from their water. Patented KDF process media are 100 percent recyclable and contain no chemical additives.

KDF 55 Medium was designed specifically for removing or reducing chlorine and water-soluble heavy metals. It controls scale, bacteria and algae, even in hot water. KDF 85 Medium removes or reduces iron and hydrogen sulfide from municipal or other water supplies. Also controls scale, bacteria and algae.
