Things to Consider

Type of Humidifier

According to international standards, humidifiers can mainly be divided into three types: ultrasonic humidifier, cool evaporative humidifier and electric warm humidifier.

1. Ultrasonic humidifier: Through the high-frequency resonance of the atomizing sheet, the pure water droplets are broken into tiny floating particles of about 5 microns, which are kept away from the pure water surface under the action of a fan or in a natural state, so that the suspended water mist is continuously produced, and finally the air is humidified. Since the oscillation frequency of this machine is 1.7MHz (there are also 2.4MHz) that can not be heard by humans, it’s a good choice for these people who are sensitive to noise.

2. Cool evaporative humidifier: This humidifier uses molecular sieve evaporation technology to remove calcium and magnesium ions from the water, increases the evaporation rate by expanding the evaporation area and speeds up the rate of air circulation on the surface of the water molecules to humidify. If you have a cold, the cool-mist humidifier can help shrink swelling in nasal passages, making it easier for you to breathe, according to the Food and Drug Administration.

3. Electric warm humidifier: Its working principle is to heat the water and generate steam, which is sent out by a motor to humidify. Most of the time, people prefer to use this one in winter. The disadvantages of this warm mist humidifier are that it consumes a lot of energy, cannot be dry-burned, has a low safety factor, and is easy to scale on the heater.


If you would prefer to pick the ultrasonic humidifier, you’d better use purified water or water that has been treated by a water purifier.

Type of Room

There are countless humidifiers on the market, which are equipped with different humidification performance. Generally speaking, It is recommended to use a humidifier with a humidifying performance of 200mL/h or more in the bedroom. If the air condition in the bedroom has a high wind speed, it is better to choose a humidifier with a humidifying performance of 300mL/h or more. Separately, a humidifier with a larger humidification performance is required in the living room, such as 500mL/h.


1. It is worth noting that the capacity of the humidifier has nothing to do with the humidification performance, but it can be filled with more water instead of frequently adding water.
2. The humidity of the humidifier should not be too high. The human body will feel sultry, hot and humid. It will also breed bacteria and easily mold. It is recommended to choose a humidifier with a smart mode and humidity control.

The Noise Produced by Humidifier

Normally, people can tolerate the noise of 30 to 59 decibels, but it is already uncomfortable when it reaches 40 decibels, which starts to disturb sleep. Therefore, in order to better sleep, the noise when we choose the best room humidifier should not exceed 40 decibels. If you are more sensitive to sound, it is recommended to choose an ultrasonic humidifier.


The best room humidifier is more easy to operate than others, such as adding water, cleaning, operating and so on.

1. Adding water: Consider whether the humidifier is convenient to add water, so as not to affect the experience.
2. Cleaning: Whether it is easy to accumulate dust or whether it is easy to clean.
