Gold Seal Product Certification

BOROUX water filter systems and filters are Gold Seal certified by the Water Quality Association (WQA), the oldest third-party certification in the water filter industry.

Products must pass rigorous testing requirements to be certified:

Industry standards (NSF/ANSI/CAN)
Annual facility audits
Comply with WQA’s Certification Schemes

Verification and validation from an independent testing process offers the reassurance consumers deserve.

NSF/ANSI Standards

NSF International (NSF) and the American National Standards Institute (ANSI), globally recognized organizations that ensure public health and safety in consumer products.

Standards are developed through a public process for balanced input from industry representatives, public health and regulatory officials, certification bodies and testing labs, and users. Products are rigorously tested and evaluated to verify that it performs as claimed, that the materials used are safe, and that the product effectively reduces contaminants from drinking water.

BOROUX Certifications:

Drinking Water Treatment Units, Aesthetic Effects

NSF/ANSI/ 42

Nominal Particulate Class I

Understanding Industry Certifications

Third-Party Verified

In order for a product to be certified, a third-party independent organization must monitor the manufacturing process for guideline adherence. Material and performance testing ensures products follow the strict standards.

Rigorous Standards

Standards are developed and enforced by experts. The specifications are specific to each different type of product to confirm the product performs as it claims. Certifications thoroughly verify satisfactory customer support.

Annual Inspections and Retesting

Certifications are not a one-and-done process. For true reassurance, products and facilities must regularly retest and allow a facility inspection. Annual renewal ensure quality remains acceptable over time.

Benefits of Product Certification

Peace of Mind

Knowing that the products are evaluated and accredited by a third-party offers a level of assurance. The WQA certifications means that products have been rigorously tested and the results can be reproduced, showing consistent performance.

Multi-Faceted Certification

Taking a holistic approach, the product's performance, the materials used, and literature provided are evaluated for safety, efficacy, and usability. Any product that comes into water is extensively considered.

Buying Power

With so much confusion and disingenuous marketing noise, an easy-to-recognize symbol like the WQA Gold Seal provide clarity. It means that the product and company has been tested, evaluated, and distinguished as high quality.

Consumer Protection

Concerned about specific contaminants? Want, need the assurance that those contaminants are truly filtered out? Certifications are the proof needed and wanted for product performance. Purchase with confidence.

Regulatory Requirements

Each state, county, and city have specific rules and regulations. Certification brings consistency and qualifications to meet the requirements for selling products in localized areas.

Monitoring Consistency

Annual testing and inspection verifies that products are consistently good. WQA programs places checks and balances to make sure products are the same and continually effective year over year.
