NSF refers to the water quality testing standard. The water quality safety testing certification standard formulated by NSF is called the high standard of the industry, and it has been adopted as the standard by many countries in the European Union, Australia and other countries except the United States. Therefore,NSF is designated by the world health organization (WHO) as the global cooperation center for drinking water safety and filtration.
WQA (WaterQualityAssociation) is short for the United States water quality association, the United States * authority of water quality association, is a representative of the water treatment industry and practitioners non-profit international industry groups, from on behalf of the general water industry enterprises and the interests of the practitioners, to provide all aspects of support and service, promote the development of the global water industry industry health effectively.
NSF certified content is very different.
In fact, there are many NSF testing criteria, such as:
NSF standard 42 water suitability test
To test the ability of the filter to remove contaminants affecting taste, smell, and clarity of drinking water to meet the conditions suitable for human drinking water.
NSF standard 53 water quality health test
It is used to test the safety of raw materials, the integrity of product structure, the accuracy of product information, and the effectiveness of filtering pollutants such as lead, cysts and VOCs, which are crucial considerations in selecting water purifiers.
NSF/ANSI standard 58 reverse osmosis drinking water treatment system
This standard mainly tests the safety and energy efficiency ratio of reverse osmosis components, and has nothing to do with the quality of water.
NSF/ANSI standard 60 potable water treatment chemicals
This standard mainly tests the chemical substances and chemical products used in the treatment of drinking water, whether they meet the standards for safe drinking water, is the test of the water purifier itself, and has nothing to do with the effect of water treatment.
NSF/ANSI standard 61 components for potable water systems
This standard mainly tests whether the toxic substances of all parts and components of water purifiers and the toxic substances in the analyzed water conform to the drinking water and food safety standards, and has nothing to do with the water treatment effect.
