The First Composting Toilet to Be Listed With NSF Standard 41

The Sun-Mar Excel was the first self-contained composting toilet in the world to be tested and listed with NSF (the National Sanitation Foundation). NSF listed Excel, 1989.

At present, Sun-Mar is the only small-load composting toilet system (cottage and regular residential use) to be listed with the NSF!!

The NSF is the only body which lists and certifies composting toilets under Standard 41. While some may test to the same standards, only NSF Listed products may bear the NSF mark (at right).

NSF tests all stages of the operation of the unit and the finished compost to exacting standards. Please click on the link here to be taken to their website.
