Dry and cold winter is coming, a lot of people want to buy the humidifier, how many humidifier to choose?

Firstly, look at the principle of humidification.

We see the misty humidifier on the Internet, is generally called ultrasonic humidifier. The price is very reasonable. The price of the other humidifier is relatively high, generally written "no fog wet" such words.

The ultrasonic humidifier structure is very simple, consisting of a water tank and atomizer. The atomized sheet in the atomizer vibrate high frequency, and the ultrasonic wave throws water off the water surface, forming a humidified water mist.

Ultrasonic humidifier has a lot of attention, such as regular disinfection and cleaning, do not use tap water, try to ensure indoor air quality. Otherwise, humidifying the water mist is easy to become an indoor haze. Use this time for a long time, such as the whole night wet, then the next day the respiratory tract will be uncomfortable.

A fog-free humidifier is expensive, but the principle is actually simpler than an ultrasonic humidifier. Strong wind is produced in the humidifier, which makes the water "evaporate naturally". Like the clothes on the balcony, when the wind blows, the clothes are dry, and the air is wet.

Fog-free humidifier is expensive because of the integration of an air purification function in the production of strong air link. At the same time, since the water was " evaporated naturally, impurities in the water are not carried into the air. Thus maintaining the indoor air at a relatively healthy level.

Of course, a fog-free humidifier can not be bought blindly.

For example, in addition of bacteria, ultraviolet UV lamp is better than silver ion alone.
