Karofi RO water purifier is certified by NSF/ANSI 58 - American safety standard

As water sources become increasingly polluted, owning a high-quality water purifier is not only a need but also a solution to protect the health of your family. Karofi RO water purifier has affirmed its position in the market thanks to achieving NSF/ANSI 58 certification - the highest safety standard for reverse osmosis water filtration systems.

This article will help you better understand the NSF/ANSI 58 standard, the rigorous testing process to achieve this certification, as well as the outstanding benefits that Karofi RO water purifier brings.

What is the US NSF/ANSI 58 standard?
NSF stands for National Sanitation Foundation, the World Health Organization (WHO) food and drinking water safety cooperation center, one of three prestigious independent, non-governmental, non-profit inspection organizations (alongside WQA - Water Quality Association, UL - Underwriters Laboratories). NSF is an independent inspection organization headed by WHO, with the function of testing and certifying product quality to ensure that consumers use safe products as described by the manufacturer.

Karofi brand information NSF/ANSI 58 CERTIFIED

This is a set of standards specifically for Reverse Osmosis (RO) water filtration systems used at the point of use, such as home water purifiers. This standard places extremely stringent requirements on the performance, safety, and ability of the equipment to remove impurities, ensuring that the filtered water is of the highest quality for direct drinking purposes.

The NSF/ANSI 58 standard applies to reverse osmosis (RO) systems. RO is a rigorous water filtration process that effectively reduces total dissolved solids (TDS), along with other contaminants such as arsenic, perchlorate, nitrate/nitrite, and many others, from water. An RO system that meets the NSF/ANSI 58 standard guarantees its effectiveness in reducing these contaminants, providing you with pure, high-quality water.

Achieving NSF/ANSI 58 certification is a testament to product quality and the manufacturer’s commitment to protecting consumer health. For Karofi – an international water purifier brand, achieving this standard has enhanced its reputation and affirmed the superiority of the RO technology applied by the brand.

Testing process to achieve NSF/ANSI 58 certification
For a product like Karofi RO water purifier to be granted NSF/ANSI 58 certification, the manufacturer must undergo a rigorous testing process, including many stages from material evaluation to actual performance testing.

List of key requirements in this process:

• Material safety: All materials in contact with water (RO membrane, filter housing, pipes, tanks, etc.) must comply with NSF/ANSI standards to ensure that no toxic substances are released into the water.
• Contaminant removal efficiency: The RO system removes contaminants and toxins according to standards.
• Structural durability: The system meets the standards for dynamic pressure and static pressure durability. No damage, durable and sturdy structure.
• Transparent and reliable certification: The manufacturer is periodically inspected to ensure that product quality always meets the standards of the NSF organization.
• Quality monitoring: The manufacturer meets the requirements for periodic monitoring (annual audit) to ensure that the system (Product) complies with the regulations and standards of the NSF organization.

Very rigorous testing process to achieve NSF/ANSI 58 certification

With Karofi RO water purifier, achieving this certification is the result of serious investment in research, development and quality control. Purifim RO membrane imported from the US - the heart of the machine - has been manufactured and tested according to NSF/ANSI 58 standards, bringing absolute peace of mind to users.

NSF standards for scoring water treatment units and drinking water use
Currently, NSF has a total of 6 standards for scoring the use and scoring of water treatment units. Specifically as follows:

• Standard No. 42: Quality standards for taste, smell, color of drinking water.
• Standard No. 44: Water softening standards by ion exchange for families
• Standard No. 53: Standards for hygiene and health safety of water treatment units.
• Standard No. 55: Water treatment system using UV rays to remove microorganisms.
• Standard No. 58: High-level standards for hygiene and health safety of reverse osmosis systems
• Standard No. 62: Drinking water distillation systems.
