Kinetico’s engineered filters and systems solve a variety of water conditions, such as cloudy water, foul smells (rotten egg), rust or blue-green stains, chlorine taste and smell, or corrosive properties. With Kinetico water filters, your water can be restored to its most pure state.

Carbon Filter

Using the most effective activated carbon on the market, Kinetico’s carbon filter removes chlorine and bad tastes and smells from your water.


Chlorine Removal Filter

This single-tank system will remove chlorine from all the water going into the home. It also protects your water softener from the damaging effects of chlorine so your water softener will have a longer life.

Macrolite® Filter

Developed in conjunction with 3M and brought to you exclusively by Kinetico, this unique ceramic media removes to a negligible level certain forms of iron, sediment, particulate matter, and turbidity.

Sulfur Guard™ Water Filter

The Kinetico Sulfur Guard® Water Filter is simple, easy-to-maintain, and effectively removes foul smelling “rotten egg” water.

Calcite System

This unique system solves the problem of acidic water by raising the pH of your water to a neutral level 7, which will remove the blue-green stains on copper fixtures and pipes or in bathtubs and sinks.


Chloramine Reduction System

Many municipalities are now using chloramine (a chemical compound made of chlorine and ammonia) to disinfect the water. Like chlorine, chloramine has an unpleasant taste and smell, and it can be corrosive to copper pipes.

Arsenic Guard® Water Filter

This no-hassle solution will remove arsenic, a deadly poison, from your water.
