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. Drinking water high in nitrate is potentially harmful to human and animal health.

Because nitrate is colorless, tasteless and odorless, water must be chemically tested to determine contamination. In levels above 10.0 ppm as Nitrogen, it is considered as a hazard to infant's health and that of animals and should be removed. Your County Health Department and many private laboratories will test for nitrate.
An ideal, low cost method for removing Nitrates is a system much like a water softener only it contains a Type II strong base Cation resin, which the CuZn Nitrate Water Filters use. The unit will remove nitrates. Hardness over 8 grains, all chlorine and iron must be removed from the water supply to the nitrate removal tank. Cation resin is a negatively charged resin bead that exchanges positively charged ions in the water. Cation resin is most often used for removing nitrates.
But CuZn water filtration products don't stop there. Using a combination of trace minerals (copper and zinc in the patented form of KDF, which meets NSF standards 42 and 61) and acid washed coconut shell carbon, the CuZn Refillable Countertop water filter removes more than 600 contaminants from water, including chlorine, lead, heavy metals, trihalomethanes (THMs), herbicides and pesticides much the same as Nature uses the earth and its minerals to cleanse water. (Unlike carbon-only filters, bacteria can't grow inside the bacteriostatic CuZn filters!)
The CuZn Nitrate Water Filter for drinking water is also excellent in situations where sulfur and iron are present and a CuZn Whole House system is not feasible. Sulfur and iron expends the media more quickly than other contaminants, so refilling the system is economical and environmentally responsible.
We offer Nitrate filters in a countertop or under-counter model. If you are interested in a whole house Nitrate filter system, give us a call toll free at 866-875-4386.
