As it appears from the name, bottleless water dispenser is referred to that kind of water dispenser which gives out a supply of drinking water continuously without any need to fasten the bottles on it. Initially, the traditional water dispensers were required to turn the bottles upside down to dispense the water. Someone would grip the container by a regulator and let the water inside the container go when a nozzle was opened. However, the bottleless water dispenser removes the need of dragging heavy water bottles and turning them upside down on the dispenser. That's why it is so relatively so famous than the traditional bottleless water dispenser.

The flow of water from the bottleless water dispenser is obtained directly from the chief water resource of the house. The process is done through a water filtration unit and then it is flowed into the dispenser. This system of water dispenser is meant for ensuring that the quality of water is pure and drinkable. The water is obtained from the resource and reserved in an interior tank from where it is dispensed if need be. Most of the bottleless water dispensers are now coming with their own filtration units. Though, they are relatively very expensive, they are user friendly too.

There is a technique called reverse osmosis by which the water is filtered. This is simply done by passing the water through a mechanical filter by applying pressure. This enables the pure water to pass on to the other end and reserves the dirty ingredients on the other side. Thereafter, the purified water is dispensed directly through the nozzles.

Bottleless water dispenser comes into different categories based on the type of water that it dispenses. It is divided into two parts- hot bottleless water dispenser and cold bottleless water dispenser. The function of hot one is supported by a heater filament with a thermostat. The heater normally heats up the water up to an appropriate warm temperature. And thermostat keeps the temperature balanced. Further, the cold water dispenser is equipped with a compressor pump, identical to that utilized in refrigerators. Even the mode of cooling the water is just the same as that of refrigerators.

Most of the bottleless water dispensers feature both cold as well as hot water facility. They are dispensed through two different nozzles. This ensures that the water dispensed is hygienically safe and ready for consumption. Bottleless water dispenser with such dual purpose property is gradually catching up in most in-home uses. There are also numbers of bottleless water dispensers having no temperature conditioning services. They simply eject the water on a roomy temperature. Further, the purity of water is uncertain, depending upon the structure and manufacturing of the water dispensers. However, they can be bought under very affordable price in the market.

Bottleless water dispenser needs to be cleaned on regular basis. Otherwise the mechanical device which allows free flowing of water will not function properly in the course of time. If regular changing is not possible then at least occasional cleaning should be maintained properly, especially at the point from where the water flows.
