Benefits of NSF Standards to Home Water Filtration SystemsNSF certification ensures that your water filtration system can filter as claimed by the manufacturer | NSF Standards were developed by the National Sanitation Foundation (NSF) International. NSF is a world renowned scientific and technical expert in the health and environmental sciences. Its professional staff consists of engineers, chemists, toxicologists, and environmental health professionals.
 NSF is an internationally recognized, not-for-profit, third-party testing organization that tests and certifies home water filtration systems to ensure they meet strict public health standards. Certified products that have been tested to verify that they meet certain standards for health and aesthetics will have the logo mark on the right. This ultimately results in giving customers the assurance that the filter system they about to buy will do what the manufacturer’s literature says it will do. Benefits of NSF certifications: - Filter reduction claims are true ensuring you are buying the right water treatment system.
- No harmful chemicals will be added to the filtered water.
- The system unit is structurally sound according to specifications.
- The filtration system is as advertised; no misleading literature and labeling.
- No change in the materials and manufacturing processes as described by the manufacturer.
| NSF Standards | Description | Aesthetic Effects (NSF/ANSI 42) |
Chlorine Reduction
System certified for chlorine reduction by meeting the minimum level of reduction required by the NSF standard, which is only 10%.
Particulate Reduction
Several classes are used to define the level of particulate reduction, ranging from Class VI for those devices removing coarse particulates of 50 micrometers and larger to Class I for drinking water treatment units that reduce the smallest (sub-micron) particles (0.5 to 1.0 micron). This includes the reduction of chlorine, chloramine, and particulate reduction.
| Softeners (NSF/ANSI 44) | Water softening devices covered by Standard 44 use a cation exchange resin, regenerated with sodium chloride or potassium chloride, to reduce the amount of hardness (calcium, magnesium) in the water. The hardness ions in the water are replaced with sodium or potassium ions. | Health Effects (NSF/ANSI 53) | System certified for reduction of microbiological contaminants (including filterable cysts), chemical (including DBFs, pesticides, herbicides, and insecticides), or particulate in nature. | Ultraviolet Treatment (NSF/ANSI 55) | This treatment style uses ultraviolet light to disinfect water (Class A systems) or to reduce the amount of heterotrophic bacteria present in the water (Class B systems). | Reverse Osmosis (NSF/ANSI 58) | Reverse Osmosis water filtration process is pressure-driven. RO water filters work best at a high pressure flow. The pressure applied is much beyond the osmotic pressure of the contaminated water against a semi-permeable membrane. RO devices effectively reduce certain heavy metals, salts, and inorganics, including healthful, naturally-occurring minerals. Contaminants extracted through the Reverse Osmosis process are returned to the water supply. The process is slow and wastes about 3 to 4 gallons for every one gallon of water produced. | Distillation (NSF/ANSI 62) |
NSF Standard 62 was developed for the Distillation technology which works very slowly and uses a lot of electricity. Water is heated to boiling and turns to vapor, leaving inorganic contaminants, including healthful minerals, behind. Chemicals evaporate along with the water and then recondense into a liquid state in the distilled water.
Distillation system can be very effective in solving most drinking water problems, especially dissolved salts which may be difficult to remove by other water purifiers. This water purification system produce almost pure water by removing microorganisms, nitrates, metals, dissolved solids, heavy metals, and unpleasant tastes and odors.
| Shower head (NSF/ANSI 177) | System Tested and Certified by NSF International against NSF/ANSI Standard 177 for the Reduction of Free Available Chlorine | | Several home treatment systems carry the NSF certification label. Among them and a leader in drinking water filtration systems is Multi-Pure. Their Drinking Water Systems have been tested and certified. to reduce particulate matter down to 0.5 micron, and to reduce chlorine, chloramine, taste and odor problems, certain pesticides, cysts, VOCs, trihalomethanes, MTBE, and PCBs and a wide range of other contaminants.
In addition to the NSF certifications, Multi-Pure drinking filter systems are certified by other state and local health departments. This is n additional layer of assurance that their will do what the literature says it will do. For instance, all Multi-Pure Drinking Water Systems have been listed, certified, and/or registered by the following: - California Department of Health Services Water Treatment Device
- Iowa Department of Public Health
- State of Wisconsin, Bureau of Building Water Systems, Research and Product Review Unit
- State of Massachusetts, Board of Plumbing
- State of Colorado, Department of Health, Drinking Water Program
