Rule of Thumb for Changing Filters. The rule we have followed for 18 years in the filtration industry is to change filters every 6 to 12 months. Six months is almost always optimum, especially in commercial/office settings, and twelve months is as long as you want to go no matter what.
Water cooler. A water cooler or water dispenser is a device that cools and dispenses water. They are generally broken up in two categories: bottleless and bottled water coolers.
