Water Filtration Certifications & Verified Performance

No. The listing covers the model, replacement component, flow rate and capacity shown on it. The certificates state that a change in material, manufacturing process, marking or design made without prior approval can be grounds for revoking the listing. We review each customized version against the listing before it is described as certified.

Not automatically. A certified product must carry the certified company name, the model number and the certification mark, as set out in the listing’s identification requirements. Selling under a different brand or model name normally means adding that name to a listing through IAPMO R&T. We prepare and coordinate the application; IAPMO R&T decides scope, timing and fees.

Yes. Media type, quantity and structure determine reduction performance, so a media change can require retesting for the affected claims, and a materials review. Treat any media change as a new evaluation until the certification body confirms otherwise.

No. The current listings cover one WP3000(US) system with one WP3000(US)-RF cartridge. Multi-cartridge layouts change the flow through each cartridge and the system capacity, so they need their own evaluation before any certified claim is made.

Often yes, when the product itself is unchanged. IAPMO R&T reviews the request and updates or issues a listing. Where the product also changes, the review covers those changes as well. We confirm the route with IAPMO R&T for each project before quoting a timeline.
