Editor's Pick: The C100 countertop cold-water RO purifier delivers 50°F crisp pure water within 5 seconds of pressing the cold-water button—no need to wait for the fridge to chill, and no risk of secondary contamination. Its 6-stage reverse osmosis filtration removes 99.9% of harmful substances, then adds back calcium, magnesium, potassium, and other minerals at the end for healthier, better-tasting water. The side-mounted water tank makes refills easy while keeping a small footprint that fits most desktops. With a 3:1 pure-to-waste water ratio, the filter produces up to 1,056 gallons of pure water and can save over 8,000 plastic bottles a year, with the waste water reusable for other purposes. Installation-free design—just plug in, add water, and it's ready to go.
