What is SGS?
SGS, formerly known as Société Générale de Surveillance, is a Swiss multinational company headquartered in Geneva that provides inspection, verification, testing, and certification services.
What is SGS certification?
While SGS certification provides some assurance of the water filter’s quality, safety, and performance, it may not be as specialized or focused on water treatment products as certifications from organizations like NSF, WQA, or IAPMO. However, an SGS certification can still be an indication of the product’s quality and compliance with relevant standards and regulations.
What is NSF/ANSI 58 Standard?
NSF/ANSI 58 is an American National Standard for point-of-use (POU) reverse osmosis (RO) systems4. It is used to certify water treatment systems employing reverse osmosis technology. To be certified under this standard, a system must meet several requirements, including:
- Material safety: Ensuring that the materials used in the system are safe and do not introduce contaminants into the water.
- Structural integrity: Ensuring that the system is structurally sound and can withstand normal use without leaking or breaking.
- Contaminant reduction performance: The system effectively reduces specific contaminants in drinking water, such as nitrate, nitrite, heavy metals like lead, copper, and mercury.
What is EPA Method 537 Standard?
EPA Method 537 is a standardized analytical method developed by the United States Environmental Protection Agency (EPA) to determine selected per- and polyfluorinated alkyl substances (PFAS) in drinking water.
