Editor's Pick: The C100 countertop cold water RO purifier dispenses 50°F crisp pure water in just 5 seconds when you press the cold water button—no need to wait for the fridge, and it eliminates secondary contamination. The 6-stage reverse osmosis filtration removes 99.9% of harmful substances, while adding back calcium, magnesium, potassium, and other minerals at the end for healthier, better-tasting water. Its side-mounted water tank design makes refilling easy and saves space, fitting most countertops. With a 3:1 pure-to-waste water ratio, the filter can produce up to 1,056 gallons of pure water, reducing over 8,000 plastic bottles per year, and the waste water can be reused. No installation required—just plug in, add water, and enjoy.
