What is a dehumidifier?

A dehumidifier is by the compressor, heat exchanger, fan, water container, casing, and controller, the fan will humid air into the machine, and through the heat exchange, the moisture in the air condenses into water droplets, the processed dry air discharged out of the machine, and so on to make the cycle of indoor humidity reduction.

A dehumidifier in a certain place supplies and improves the quality of human life indispensable product, and its market prospects are very large. Scientific research reports point out that the human body the survival in the environment has high requirements for humidity, with relative humidity to 60-70% for good, the best winter can not be less than 50%, and summer can not be greater than 80%.


Which situations is the dehumidifier suitable for?

High temperature and Rainy season: dehumidification dehumidifier’s core role of dehumidification, for rainy and humid weather, floor, and wall beads of water, mold everywhere, and other phenomena, dehumidifier reduces indoor humidity, and keeps the house dry.

Storage room and Basement: storage of some items, such as medicine, high-precision utensils, cultural relics, books, etc. need to be stored in a dry condition, so dehumidifiers are needed to dehumidify the room and keep it dry for storage in the above items; Basement with less sunlight needs dehumidifiers to dehumidify the room.

Wet areas:70%-80% humidity is the peak of mold and bacteria growth, dehumidifiers can reduce humidity and mold growth.

Housing and Family: a dehumidifier can be added to the residential area to keep the indoor humidity within the right range for good health.

Benefits of dehumidifier.

Efficient dehumidifier: The function of a dehumidifier is to reduce the moisture in the air, and regulate the humidity in the air by converting the moisture in the air to liquid through the device.

Regulate humidity: If the humidity in the room is too high, it will make people feel that the air is not circulating well, and they will not be able to breathe well, which will affect the health of the body. Dehumidifiers can regulate the humidity and make people feel comfortable in lower humidity.

Prevent bacteria and mold from multiplying: If the humidity in the room is too high, there will be a lot of bacteria and mold breeding. A dehumidifier can keep the humidity at about 60%, which can greatly reduce the growth of bacteria and mold.

Preventing electrical appliances from getting damp: Electrical equipment in a humid environment is prone to circuit damage, short circuits, and in more serious cases, fires. The use of dehumidifiers can be a very good control of humidity, effectively preventing electrical equipment from moisture, to avoid all kinds of danger.

Disadvantages of dehumidifiers.

Higher energy consumption: driven by electricity, which may increase the cost of household electricity under long operation.

Noise problem: some older models or more powerful dehumidifiers may have noise problems, which may not be suitable for users who need a quiet environment.

Frequent cleaning and maintenance: in order to maintain good results and extend the service life, dehumidifiers need to regularly clean the water tank, filter, and other components.

Dehumidifier purchase points.

Dehumidifying capacity

Dehumidification and dehumidification area, the industry reference standard formula: the theoretical number of daily dehumidification * 2 = theoretical maximum dehumidification area.

The larger the dehumidification capacity, the weaker the compressor, the stronger the energy consumption, and the noise is also more obvious, do not recommend too much pursuit of dehumidification capacity.

Use area and daily dehumidification capacity reference

Single room30㎡Within 15L
Small house3.-80㎡14L-40L
Large household80-150㎡40L-75L

Smar dehumidifier


The structure of the dehumidifier involves fans and compressors, noise can not be avoided, it is recommended that the noise of the dehumidifier for home use should not be too high, and can be controlled within 45 decibels.

Other functions

(1) auxiliary functions. Common auxiliary functions will be the drying function and air purification function; dehumidifier The main dehumidification function, auxiliary function compared with professional equipment, the effect is definitely discounted. It is best to choose according to the actual needs, after all, adding 1 more function, the price will be more expensive.

(2)hardware. Here are two main considerations, the quality of the compressor and the volume of the tank Compressor quality can be selected to pick a good reputation of the big brands, relatively speaking, is not easy to step on the pit; the volume of the tank size determines how often we empty the tank, in the same dehumidification capacity, the larger the volume of the tank the better; in addition, if the amount of dehumidification reaches 12L or more, it is best to choose the wheels, easy to move.

Please note.

Many people in order to dehumidify the purchase of dehumidifiers, but if you do not pay attention, you will walk into the use of these misunderstandings!

Error 1: Placed against the wall. At present, most of the dehumidifiers on the market use rectangular or square bodies, moisture from the back or side into the body, if the machine’s inhalation surface is placed against the wall, at least one inhalation surface is blocked, can not play the role of wind, the loss of a certain degree of dehumidification efficiency.

Error 2: Do not close the windows and doors when using. Dehumidifier dehumidification principle is to draw indoor air into the machine through the professional dehumidification device (cooling dehumidifier and rotor a cycling process, so you need to close the doors and windows, indoor air mobility is small, in order to ensure that dehumidification can be more rapid.

Error 3: Dehumidifier goods immediately used. Many people like fresh, dehumidifiers to the home immediately installed to try the effect, in fact, this is not true. In the transportation process, the dehumidifier may be in the bumps in the compressor refrigerant displacement, if immediately open, the dehumidifier is likely to not work properly, or the dehumidification effect is not good, noisy, and so on. Therefore, it is best to place 4-6 hours before use.

The sharing of dehumidifiers is here, I believe you have a certain understanding of dehumidifiers. For enough to buy which dehumidifier editor in so do not recommend, you can do your homework before buying, I hope you can buy your favorite products.
