Humidifiers are mainly classified into two types based on their uses: household humidifiers and industrial humidifiers. The ultrasonic humidifier uses ultrasonic high-frequency oscillation at a frequency of 1.7MHZ to atomize water into ultrafine particles of 1-5 microns, which can freshen the air, enhance health and create a comfortable environment. According to experts, the advantages of ultrasonic humidifiers are that they have a strong humidification intensity, uniform humidification and high humidification efficiency. Energy-saving and power-saving, its power consumption is only 1/10 to 1/15 of that of an electric heating humidifier. Long service life, automatic humidity balance, and automatic protection when there is no water. It has functions such as medical nebulization, cold compress face bathing, and jewelry cleaning. Direct evaporation humidifiers are also often referred to as pure humidifiers. Pure humidification technology is a newly adopted technology in the humidification field. Pure humidifiers remove calcium and magnesium ions from water through molecular sieve evaporation technology, completely solving the "white powder" problem. 

The thermal evaporation type humidifier is also called the electric heating type humidifier. Its working principle is to heat water in the heating element to 100 degrees, generating steam, and then use a fan to send out the steam. Therefore, the electric heating humidifier is the simplest humidification method in terms of technology. However, it has the disadvantages of high energy consumption, inability to dry burn, low safety factor, and easy scaling on the heater. The market outlook is not optimistic. Electric heating humidifiers are generally used in conjunction with central air conditioning systems and are not used alone. Compared with the above three, the electric heating humidifier does not have the "white powder" phenomenon during use, has low noise, but consumes a lot of electricity and is prone to scale formation on the humidifier. The pure type humidifier has no "white powder" phenomenon and does not form scale. It has a low power consumption and an air circulation system that can filter the air and kill bacteria. The ultrasonic humidifier has a strong and uniform humidification intensity, low power consumption, long service life, and integrates functions such as medical atomization, cold compress face bathing, and jewelry cleaning. Therefore, ultrasonic humidifiers and pure-type humidifiers are still the recommended preferred products.
