Ozark River Portable Sinks® (self-contained mobile hot water hand-washing stations) received NSF/ANSI 169: Special Purpose Food Equipment and Devices certification to establish credibility and grow and develop the business. Entering the market with a unique product is always a challenge because buyers are typically cautious about investing in products with a short history. “For our product, it was essential to have an NSF International certification. The certification was so important because it forced us to reevaluate our product from the ground up and figure out what we needed to alter to make it the best possible product it could be,” said Watts.
