Are You Certified by NSF or to NSF?
NSF/ANSI 41 certifies composting toilets and similar treatment systems that do not use a liquid saturated media as a primary means of storing or treating human excreta or human excreta mixed with other organic household materials.
The standard requires a minimum of six months of performance testing, which includes design loading and stress testing appropriate to the product class: residential, cottage or day-use park. We evaluate a minimum of one system in a controlled laboratory setting, and a minimum of three systems in a mature field setting.
