At The Healthy House® we believe we can only endorse our products if we are comfortable with their performances. Our drinking water and whole house water filtration products have all been independently tested. There are a number of third-party independent testing standards that our products may be covered by and these are:
NSF accredited third-party certification provides assurance that a certified product complies with the technical requirements of the referenced standard.
NSF writes standards and provides testing and certification services for drinking water treatment. It includes both systems and components. Testing can include material safety, structural integrity and contaminant reduction testing. They certify thousands of products to various local and global standards
NSF developed its first drinking water treatment standard in 1973. Today, NSF test to seven drinking water treatment standards.
The NSF standards address the wide array of drinking water treatment technologies on the market today. These include adsorptive media, ion exchange, reverse osmosis, ceramic filters, shower filters and more.
Each NSF standard sets thorough health requirements and performance criteria for specific types of products. Contaminant reduction claims can be certified under each standard. They can vary according to each water treatment technology capability. Systems that use more than one treatment technology may be certified under multiple standards.
The NSF certification process is specific to each product. The certification follows seven steps:
The NSF standards used by our products include:
NSF/ANSI 42 establishes the minimum requirements for the certification of systems designed to reduce non-health-related contaminants.
The scope of NSF/ANSI 42 includes material safety, structural integrity and non-health-related contaminant reduction. The most common technology addressed by this standard is carbon filtration.
NSF/ANSI 53 establishes the minimum requirements for the certification of systems designed to reduce health-related contaminants. These include Cryptosporidium, Giardia, lead, volatile organic chemicals (VOCs) and MTBE (methyl tertiary-butyl ether).
The scope of NSF/ANSI 53 includes material safety, structural integrity and health-related contaminant reduction. The most common technology addressed by this standard is carbon filtration.
NSF/ANSI 401 addresses the ability of a water treatment device to remove up to 15 individual contaminants (listed below). These have been identified in published studies as occurring in drinking water. While not a public health issue, the contaminants covered in NSF/ANSI 401 have been detected in drinking water supplies at trace levels.
(NSF/ANSI 401 also applies to reverse osmosis (RO) water treatment.)
Herbicides and Pesticides
NSF/ANSI 58 establishes the minimum requirements for the certification of systems designed to reduce contaminants.
The scope of NSF/ANSI 58 includes material safety, structural integrity and total dissolved solids reduction. It can also include other optional contaminant reduction claims. The most common optional claims addressed by NSF/ANSI 58 include cyst reduction, hexavalent and trivalent chromium reduction, arsenic reduction, nitrate/nitrite reduction, and cadmium and lead reduction.

NSF/ANSI 177 was developed to cover the safety and performance of shower filtration products. Certification to NSF/ANSI 177 confirms a product’s material safety, structural integrity, minimum flow performance and its ability to reduce chlorine.
ISO are the International Organisation for Standardisation. They develop and publish international standards for products and services.
The ISO 9001 quality assurance addresses various aspects of quality management. The standard provides guidance and tools for companies and organisations. It ensures their products and services consistently meet customer’s requirements. It also requires that quality is consistently improved.
WRAS stands for Water Regulations Advisory Scheme. Its purpose is to contribute to the protection of public health by preventing contamination of public water supplies. It encourages the efficient use of water. It promotes and facilitates compliance with the Water Supply (Water Fittings) Regulations.
