What is a filtered water dispenser? A filtered water dispenser is a type of refrigerated water cooler that generally has two faucets fitted on the front of the dispenser so that a cup or small bottle can be filled. The water supply to the dispenser is fed from an outside water supply, which is easily attached to the back of the water cooler. There is no drain line required on this style of water cooler, therefore making it very easy and cost efficient to install.
