Kitchen Sink Filters

The water filtration products in this section are designed for kitchen point of use. We offer three main styles:

  • Countertop, which sits on your kitchen counter and comes with its own swivel spout.
  • Countertop double diverter, which has a twin-hose set-up so that water enters the filter from the kitchen faucet, goes through the filter, and then returns to the kitchen faucet where it is released. The advantage of the double diverter model is that the filter body can be set back away from the sink.
  • Under-counter, which is installed beneath the kitchen sink and requires a spout to be installed.  

 IMPORTANT NOTE: Delta Faucets DO NOT WORK with CuZn Countertop Water Systems

We also carry countertop and under-counter water filters that remove chloramine, arsenicfluoridenitrates and cysts/pharmaceutical drugs.

CuZn Refillable Double Cartridge Arsenic and Copper-Zinc/Coconut Shell Carbon Filter

!
Remove Arsenic, Chlorine, Sediment, Algae, Molds, Scale, Bad Taste, Odors and Other Contaminants from Your Drinking and Cooking Water

Arsenic is a semi-metal element that is odorless and tasteless. It enters drinking water supplies from natural deposits in the earth or from agricultural and industrial practices.

Non-cancer effects can include thickening and discoloration of the skin, stomach pain, nausea, vomiting; diarrhea; numbness in hands and feet; partial paralysis; and blindness. Arsenic has been linked to cancer of the bladder, lungs, skin, kidney, nasal passages, liver and prostate.

CuZn Refillable Double Cartridge Chloramine and Copper-Zinc/Coconut Shell Carbon Filter

!
Remove Chloramine, Chlorine, Sediment, Algae, Molds, Scale, Bad Taste, Odors and Other Contaminants from Your Drinking and Cooking Water

Chloramines are formed during a reaction between chlorine and ammonia in water treatment.  Chloramine reacts with organic matter less often than chlorine, thus little to no trihalomethanes (THM) and other disinfection byproducts are formed during chlormaine disinfection.

Chloramines remain actively within the plumbing much longer because it takes long for chloramines to be broken down.  Like chlorine, chloramines are selectively reactive and may have damaging affects when they remain in the water for too long.

CuZn Refillable Double Cartridge Nitrate Double Cartridge Water Filter

!
Drinking water high in nitrate is potentially harmful to human and animal health. Nitrate (NO3) is a naturally occurring form of nitrogen (N) which is very mobile in water. It is essential for plant growth and is often added to soil to improve productivity. Water moving down through soil after rainfall or irrigation carries dissolved nitrate with it to ground water. In this way, nitrate enters the water supplies of many homeowners who use wells or springs.

CuZn Refillable Triple Under-Counter Cartridge with Fluoride, Chloramine, KDF Copper-Zinc and Coconut Shell Carbon Filters

!
Remove Chloramine, Chlorine, Fluoride, Sediment, Algae, Molds, Scale, Bad Taste, Odors and Other Contaminants from Your Drinking and Cooking Water

Fluoride is a severe biological poison. Being intensely negative, it unlatches positive hydrogen bonds in enzymes and proteins. Most states add at least 1 ppm of sodium fluoride or fluorosilic acid (radioactive toxic waste that contains fluoride) to the water supply, even though it has been proven that at least 113 medical side effects from cancer to headaches are caused by fluoride in the water.

Chloramines are formed during a reaction between chlorine and ammonia in water treatment.  Chloramine reacts with organic matter less often than chlorine, thus little to no trihalomethanes (THM) and other disinfection byproducts are formed during chlormaine disinfection.
