Editor's Pick: The C100 countertop cold water RO purifier delivers refreshing 50℉ pure water with just a 5-second press of the cold water button - no need to wait for refrigeration and eliminates secondary contamination. Its 6-stage reverse osmosis filtration removes 99.9% of harmful substances and adds back essential minerals like calcium, magnesium, and potassium for healthier, better-tasting water. The side-mounted tank design makes water replacement easy, takes up minimal counter space, and fits most desktops. With a 3:1 pure-to-waste water ratio, each filter produces 1,056 gallons of purified water, reducing plastic bottle waste by 8,000+ bottles annually, while the wastewater can be repurposed. Simply plug in and add water - no installation required.
