NSF Certificate

The NSF certification mark means:

The product has undergone rigorous testing: conducted in laboratories by NSF's own scientists and engineers.

The product meets specific public health standards: these standards are typically NSF/ANSI standards (e.g., NSF/ANSI 42, 53, 401, etc., commonly found for water purifiers).

The manufacturing process is continuously monitored: NSF conducts unannounced factory inspections to ensure continuous compliance with regulations.

Labels and claims are truthful and accurate: claims on the product must be consistent with the certification content.
