Does ZeroWater Reduce Manganese?
YES! When tested in accordance with the NSF's protocol based on a 40 gallon filtration (double the rated usage), ZeroWater removes 98% of Manganese from your tap water.
The Premium 5-Stage Ion Exchange Water Filtration System reduces more contaminants than standard 2-Stage filters.Show me how it works
How does Manganese get into your water?
There are two forms of Manganese in the environment: Inorganic and organic compounds.
Inorganic Manganese compounds are used in the production of steel, batteries, ceramics and dietary supplements. These manganese compounds are also generated as combustion products from motor vehicles and coal-burning industrial plants.
Organic Manganese compounds are used in some pesticides, fertilizers and in a gasoline additive called Methylcyclopentadienyl manganese tricarbonyl (MMT).
Manganese compounds can be present as dust particles in the air and dissolved in groundwater or drinking water.
Manganese is the twelfth most common element in the crust of the earth and its compounds are widely distributed. It is a very reactive metal and exists in seven oxidation states.
The most important and stable oxidation state is divalent Manganese, Mn(II).
Elemental Manganese dissolves readily in dilute acids. Its physical and chemical properties resemble those of iron.
The most important naturally occurring Manganese compounds are:
- manganese dioxide MnO2 (pyrolusite)
- dimanganese trioxide Mn2O3 (braunite, manganite)
The Health Implications of Manganese
A very good an in-depth article on Manganese can be found here:
Manganese is a mineral that, in very small amounts, is essential for proper functioning of the human body.
It is a trace mineral present in the human body in small quantities, primarily in the bones, liver, kidneys and our pancreas.
Manganese is important in connective tissues, in the formation of bones and blood-clotting factors, and is also involved in fat and carbohydrate metabolism, calcium absorption and blood sugar regulation.
Manganese can enter into the human body through a variety of ways, including:
- Air: Manganese can be found in air but generally not at levels which should concern you when exposed. However, Manganese and Manganese compounds can be of higher concern near industries processing some of the products mentioned above.
- Water: Although not generally found at elevated levels in surface water, Manganese is a common natural constituent of groundwater. Elevated concentrations of Manganese may exist in some groundwater due to certain bedrock formations or pollution sources. In New England, Manganese and Iron are common partners in many water supplies, particularly in well water. Black deposits or dark stains in sinks, dishwashers and other fixtures are typical symptoms indicating elevated Manganese levels.
- Diet: Manganese may be found in infant formulas and breast milk, leafy vegetables, some cereals, fruits and fruit juices. Elevated intake of Manganese above recommended amounts may be of concern in some dietary situations.
According to the Environmental Protection Agency (EPA), the World Health Organization (WHO) , Manganese at very high levels can pose a neurotoxic risk.
Exposure to high concentrations of Manganese over the course of several years has been associated with toxicity to the nervous system, producing a syndrome that resembles Parkinsonism. This type of effect may be more likely to occur in the elderly.
Higher risks for children
Children are considered to be particularly susceptible to possible effects of high levels of Manganese exposure because they absorb more and excrete less Manganese than adults.
This adds up to a greater potential for exposure in the very young. Since Manganese’s effects on the developing nervous system have not been adequately studied, it is especially prudent for pregnant women and young children to have drinking water that is below the Manganese recommended level.
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.
