The Only Self-Contained Composting Toilet to Be Listed With NSF
Standard 41 is the composting toilet standard in North America,
and is the toughest standard of its kind in the world.
In 1989, the Sun-Mar Excel was the first product ever to be listed
by NSF (National Sanitation Foundation) under this Standard. Today,
the Excel (self-contained unit) and all 15 Sun-Mar central units
are the only products to be tested and certified under the residential
and/or cottage categories.
Products are only certified by NSF after an exhaustive 6 month test,
backed up by satisfactory experience in the field, which requires
amongst many requirements that there is to be no odor, even during
overload testing, and the compost produced has to contain extremely
low levels of fecal coliform.
