NSF P231 Certified Water Filters

CB Tech’s NSF P231 filter certification verifies the integrity, performance and quality of our high-performance carbon blocks, which feature our CB Tech Nanomesh™ Technology and vast customization options that adapt to your unique purification needs.

A Leader in Performance Validation

Known worldwide, NSF International has developed public health and safety standards for more than 70 years. Their role as an independent third-party testing and certification provider has defined them as a leader in validating the performance of products worldwide, including CB Tech’s NSF-certified carbon blocks.

Qualifying for NSF P231 Certification

Safety. Performance. Purification. NSF Protocol P231 demands these features at the microbiological level. Intensive NSF testing confirmed all three of these factors in our proprietary CB Tech Nanomesh™, checking critical levels of bacteria, viruses and cysts.

Additional features tested and reviewed by NSF include:

  • Structural integrity
  • Product labeling
  • Filter materials
  • Manufacturing processes

NSF P231-certified water filtration systems are engineered for applications that demand an unparalleled level of sanitation, such as in schools, residential communities, food processing centers, military bases, restaurants and other facilities that handle food and deliver water.

Standards for NSF P231 filter certification are based on recommendations defined in the Task Force Report, Guide Standard and Protocol for Testing Microbiological Water Purifiers, which the U.S. Environmental Protection Agency (EPA) created.

Competitive Advantages of NSF P231 Filters

CB Tech’s NSF P231 filters provide a competitive advantage that emphasizes safety and performance. Tests conducted by NSF — which are re-tested every five years — demonstrate that our NSF P231 certified water filters deliver up to a six-factor purification of cysts, bacteria and viruses, which they remove at the following rates:

  • 9999 percent of bacteria
  • 99 percent of viruses
  • 9 percent of cysts

Across most of the U.S., NSF certification is optional. At CB Tech, we require it. An NSF P231 filter certification verifies to consumers and manufacturers that our CB Tech Nanomesh™ Technology provides the safety, performance and purification your facility requires.
