What else should I look for when buying a water cooler?

Home and Small Office:
Water coolers are sold at retail stores and also through some bottled water distributors. If you are purchasing from a store or off the web, look for the ENERGY STAR on the box or the unit itself. If buying or leasing from a bottled water distributor, tell the distributor that you want an ENERGY STAR certified model. A list of certified models is available in the right hand sidebar of this page.

Commercial:
When requesting bids for bottled water service that include provision of water coolers, clearly state a preference for ENERGY STAR qualified models in the request for bids. See UMaine Case Study - Purchaser Version PDF icon (77KB) for an example.

Note: Point of use (POU) water coolers are now covered under the current ENERGY STAR specification.
