nyone can design a waterless toilet, but every unit must be certified by the National Sanitation Foundation (NSF) to meet NSF Standard 41 Non-Liquid Systems, tested by an ANSI-accredited third-party agency.
These certifications, performed by a Nationally Recognized Testing Laboratory (NRTL), validate that Separett toilets meet the rigorous safety standards required for use in North America. In addition to independent testing, some U.S. states have individually reviewed Separett systems.
