NSF, National Sanitation Foundation, is a non-profit organization that presents design criteria for food service equipment that is guided by sanitation and health requirements.

If you expect heavy usage or institutional use, consider purchasing 14 gauge stainless. If your usage is more "typical", 16 gauge will suit your needs.

The food waste that is processed by a disposer is 100% biodegradable. Using a disposer helps ease the strain on our country's landfills.
The following chart shows garbage disposer sizes by horsepower and meals served.
