Performance and Certifications

Sun-Mar™ composting toilet systems are CSA certified for electrical features under CSA file number LR55925.

NSF/ANSI 41 Standard — Non-Liquid Saturated Treatment Systems

This system is certified for liquid containment, odours, and solid end products.

Testing is conducted for 6 months at an NSF-recognised, independent testing laboratory under a strict protocol. To be certified, the unit must operate odour-free at maximum capacity and produce clean, safe compost.
