The 3M Cuno CS-51 Water Filter is designed for use primarily in vending systems and commercial drink machines, but is compatible with any system that uses the CS-52 or CS-451 water filters. The CS-51 filter reduces chlorine and scale to provide clearer, better tasting water for up to 1500 gallons of use. Does your filtered water have a poor taste or odor? It’s time to change out your old filter cartridge for a new one.
