A good humidifier should look like this:
Intelligently adjust the amount of humidification
A high-quality humidifier can automatically adjust the amount of humidification until the room humidity reaches the ideal relative humidity.
Match your room size
Each humidifier has its own applicable area. Choose a model with this parameter greater than or equal to the area of your room.
Does not produce white powder
This shows that the output water mist is pure and beneficial to health.
If you use a low-quality ultrasonic humidifier, the mineral impurities in the water will be broken into particles, which will directly float into the air, and when they are deposited, a layer of white powder will be spread on the furniture and the floor. The humidifier that produces white powder brings secondary pollution to the air.
Generally speaking, 30~40dB is a relatively quiet normal environment, and the noise of the humidifier should also be within this range.
Easy to add water
One is that the size of the water tank should be appropriate, and there is no need to move the water tank around every half day. The second is that the irrigation method should be scientific, which is reflected in the detailed design of the water inlet.
Easy to carry
Don’t be too heavy. Don’t be too big. Don’t be too weird. There are wheels.
The above indicators are arranged in order of importance.
Start from the mist, understand the humidifier
Not all humidifiers have white fog when they work, nor is it that the greater the fog, the better the humidification effect.
Direct evaporative humidifier. The fan sucks the dry air in the room and makes it pass through the moist evaporating core, and the water molecules re-enter the room with the air to achieve the purpose of humidification. At the same time, part of the dust and bacteria in the outside air remain on the filter element, which achieves the purpose of purification while humidifying. In the process of using, you can’t see any signs, except that the hygrometer’s indicator is constantly rising.
The classic white mist-wound humidifiers are mostly ultrasonic. The atomizing plate vibrates at high frequency to produce fine water mist below 5 microns, and then the water mist is blown into the air by a fan. When the fine water droplets converge, a white mist is formed. Ultrasonic humidifiers are quiet and efficient, but they are more likely to produce “white powder” than pure humidifiers.
High-end ultrasonic humidifiers are often equipped with sterilization rods and other equipment to reduce the secondary pollution of the air by impurity particles.
When the pure humidifier is working, the built-in fan can diffuse the humidity-rich air to the entire room. On the contrary, the mist of an ultrasonic humidifier often falls to the ground and condenses into droplets after drifting for 0.5 meters. This means that under the same humidification conditions, a pure humidifier without white fog can often humidify a larger area of air and bring a more uniform humidification effect. But correspondingly, the rate of increase in humidity may also decrease.
What reflects the humidification strength is not whether there is white fog or not, but the rated humidification capacity of the product. The terminology of humidifier products on the market that indicate this parameter is often not standardized, such as “humidification capacity”, “humidification rate”, etc. In short, remember that the unit is the parameter of ml/h or gallon/d.
The accurate definition of the rated humidification capacity is “the ability to atomize water within 1 hour in the maximum humidification state under rated working conditions.” For example, the rated humidification capacity of a humidifier is 360ml/h, which means that 360ml of water can be atomized in one hour when it is turned on to the maximum gear. The larger the value, the stronger the humidification capacity, and it is also suitable for larger rooms.
