Does ZeroWater Reduce Nitrites?

YES! When tested in accordance with the NSF's protocol based on a 40 gallon filtration (double the rated usage), ZeroWater removes 81% of Nitrites from your tap water.

The Premium 5-Stage Ion Exchange Water Filtration System reduces more contaminants than standard 2-Stage filters.

How do Nitrites get into your water?

 

Nitrite is a salt or ester anion of Nitrous acid. Nitrites can be naturally or artificially occur in your local groundwater

Nitrites come from fertilizers through run-off water from sewage and mineral deposits.

Nitrite is often used to help certain manufacturing processes of the food production industry. Curing of meat products is often performed to inhibiting the growth of bacteria.

Sadly it can also stimulate the growth of bacteria when introduced in higher levels into a body of water.

Wikipedia tells us Nitrite Salts are made like this:

Sodium Nitrite is made industrially by passing "Nitrous fumes" into aqueous Sodium Hydroxide or Sodium Carbonate solution:

The product is purified by recrystallisation. Alkali metal Nitrites are thermally stable up to and beyond their melting point (441 °C for KNO2). Ammonium Nitrite can be made from Dinitrogen Trioxide, N2O3, which is formally the Anhydride of Nitrous acid:

2 NH3 + H2O + N2O3 → 2 NH4NO2

This compound or molecule may decompose explosively on heating.

In organic chemistry nitrites are used in diazotization reactions.

 

The Health Implications of Nitrites

High levels of Nitrites are toxic to all humans and many animals. Infants and all unborn foetus are even more susceptible.

Nitrite can enter our body as Nitrate. All plants need it and it is essential for their growth. Often it is converted into Nitrite.

This can have an adverse effect or disrupts the oxygen delivery and ability of hemoglobin in the bloodstream.

Infants can develop a life threatening blood disorder commonly known as the 'blue baby syndrome' (Methemoglobinemia) when exposed to it in water or formulas mixed with water that is contaminated with Nitrate.

How are the ZeroWater filters tested?

Test results as performed by 3rd party laboratory is based on NSF/ANSI testing protocol of pour through devices for contaminants listed under the National Primary Drinking Water Standards.

Contaminants were tested at the average Influent Challenge Concentration levels as established under testing protocols by contaminant type. Results shown are based on a 40 gallon filtration, double the rated usage to ensure consumer safety.

These results are calculated from an average of two pH's (6.5pH and 8.5pH) * Indicates NSF Certified Contaminant reduction percentages for ZeroWater. These results are calculated from an average of two pH's (6.5pH and 8.5pH) Testing performed Quality Filter Testing Laboratory, LLC located in Wilmington, DE. Quality Filter Testing Laboratory, LLC is an independent ISO 17025 laboratory certified by WQA and IAPMO to test water filters as per NSF/ANSI Std 42, 53, 58, 401, 473, P231.
