Water is the source of life, and drinking water directly affects our health. Many families choose to use a water dispenser in order to drink water quickly and easily. The water dispenser does bring us a lot of conveniences, but there are many things to be aware of when using it.

Once It’s ignored, it will bring hidden dangers to our health. What kind of water dispenser is good? How to clean a water dispenser? How to correctly use it? Let’s take a look.

How Does It Work?

The principle of the water circulation inside the water dispenser is realized by the negative pressure. The bottom of the water bottle is sealed. When the water bottle is inserted, the internal pressure is less than the atmospheric pressure of the outside, ensuring that the water in the bottle does not flow out.

When dispensing the water, the water level in the water tank drops, and the air enters the bottle form below so that the water in the bottle enters the water tank.


1. Shape

Desktop: Generally, there is no disinfection cabinet or locker, so It’s small in size, convenient to move, and cheap. However, the function is single, there is no place for the cup to be placed, the design is older. It’s an inconvenience because it occupies the desktop space.

Vertical: The upper part is the water dispenser, the lower part is the disinfection cabinet or locker, which can disinfect the tea set or store the fresh food. Some models are also equipped with a small freezer for frozen drinks. It needs a permanent place for the unit.

Wall-mounted: The way of heat is not required to store water in the water tank so it can prevent reboil water. It’s thin, beautiful and space-saving. It has a temperature display. You can see the water temperature at a glance. Automatic standby when not taking water, saving power.

2. Water Temperature

Normal Temperature: It mainly provides two types of water, normal temperature, and hot water. It does not have a cold effect. Although the price is the cheapest, due to the single function and global warming, people have more eager to cold water so this type is not popular nowadays.

Hot & Cold: It’s provided with cold and hot water. It does not provide a normal temperature. The body has only one power switch. Because this type has only one switch, it can’t control the cooling and power-off, so the power consumption can not well controlled. The function of the product cannot be changed according to people’s needs. It’s wasteful in winter.

Hot, Cold & Normal: It can provide three kinds of water. It has independent switches, one power switch and the cooler switch. This kind of water dispenser has a comprehensive function and the structure is also complicated. The price is relatively expensive, which is not conducive to maintenance.

Cleaning Misunderstanding

1. The water dispenser can heat, cool, and dispense water. Does it mean the unit has no problem?

This only indicates that there is no problem with the function of the water dispenser. Because it involves human health, the water dispenser needs regular maintenance (disinfection, cleaning).

2. Often washed with detergent, it will be clean

It’s only the appearance of the water dispenser is cleaned. The core part of the water dispenser is the water tank and connecting pipe hidden inside. It’s a place that is really easy to deposits and breeds bacteria and viruses.

3. Soaking and rinsing with hot boiling water can kill bacteria and viruses

It can only kill a very small number of bacteria. It’s necessary to use a special disinfectant and it has strict regulations and requirements for its use and soaking time.

4. Only clean when you find odor or deposit

Under normal use, based on the quality of the water. It should be fully disinfected between 2 and 3 months.

5. It’s enough because there is a water station free cleaning (traditional pill cleaning)

The traditional drug cleaning method can not achieve the effect of descaling and disinfection, and the water supplier without professional training and no professional cleaning equipment so will cause secondary pollution to the water dispenser.

What Is The Hot Water Temperature Of The Water Dispenser?

There is no industry standard. It’s usually 85 °C, 90 °C, 92 °C, and will not reach 100 degrees Celsius. Because it’s pure water, it does not need to be boiled.

Experts advise that the temperature setting of the water dispenser should be at least 85 °C, and should be cleaned and disinfected regularly with disinfectant.

Is the Water Safe To Drink If less than 100 °C?

At present, most water dispensers are heated by hot tanks. The actual heating temperature is only 85-90 °C. It’s impossible to completely boil. For some high-end products, the heating temperature may reach 90 °C or above. When the water is boiled, water vapor is generated, which is harmful to the inside of the water dispenser.

Water Dispenser Health Principles

Do not keep the water dispenser on all the way. According to reports, the heating temperature is mostly 75 °C-95 °C, a few brands can reach 100 °C.

The high temperature can kill the bacteria completely. If the heating is on for a long time, it will not good for health.

Drink Fast

Pure water instead of mineral water. Bottled water should be finished within one week. If the family population is small, the bottled water is best to choose pure water. Compared with pure water, tap water and mineral water are more likely to produce bacteria.

The water dispenser should be cleaned and disinfected once a month to one and a half months.

Why Do Bacteria Breed?

The water dispenser is very easy to breed bacteria during use. If there is no regular cleaning, the water will contain a lot of bacteria that can easily cause illness and bring hidden dangers to people’s health.

To kill bacteria must start from the source. Why does water dispenser have bacteria?

1. Do not perform professional deep sterilization and descaling cleaning on the water dispenser for a long time.

2. Changing the water causes the water inlet to contact with the air.

3. The storage space is small or unclean, the air is not convective, and the ground is not clean.

4. The temperature is not appropriate, placed in cold and humid or direct sunlight, easy to cause bacterial reproduction.
