A mini water cooler is a mini version of a large water dispenser unit, only they take up much less space. They are filled with filtered drinking water and are usually used in place of regular tap water. The average mini water cooler can hold approximately eight glasses and is convenient to use in a cubicle, small office, hotel room, dorm room, or to take camping.

These can also be changed the same way as a larger water cooler, but in a more convenient way since they are easier to carry and move when putting in a new one. The water dispenser is also smaller and can be sold with the water cooler. Because of their smaller size they can be moved and placed neatly out of the way or set directly on your desk, counter top or any other place that can be reached conveniently

A mini water cooler can usually be found for as little as under $20.00. If wanting a more sophisticated look for your mini water cooler, these can usually range from $20.00-$60.00. This mostly depends on the type of water dispenser since the actual water cooler dispenser will get changed out each time it is empty and the dispenser is always kept.

The mini water cooler is more for one person use and not a large amount of people, since it only holds the recommended daily amount of water one should drink. Since that is the case, a lot of the best mini water coolers come in different designs and colors to be more personalized. There are pink ones, blue ones, green ones, plain ones, penguin ones, Hello Kitty ones, red ones, wood ones, and you can even find stickers to make your own design.

When replacing or refilling your water cooler you can have them ordered through a water filling company that comes directly to your house or office or these can be refilled by taking them to a place that provides that service. Usually a local grocery store or gas station has the means to allow you to take your old water cooler in and bring a newly filled one home and the old plastic container is cleaned and reused. The water that is used for the water coolers is the same filtered water found in bottled water. The only difference is because of the recycling of the larger or mini water coolers, the buildup of plastic water bottles is greatly reduced.
