Before also to the new air purifier customer service asked this question, the following is the other party’s answer, more easy to understand, I hope to help you:
1, ultrasonic humidifier: through ultrasonic vibration, the water into very small water droplets, and then spray out. Visible water mist. This kind of humidifier will affect the judgment of the purifier sensor, the laser sensor can not distinguish whether it is particulate matter or water molecules, it is uniformly considered to be particulate matter, and then the machine automatically adjusts the wind speed operation.
2, evaporative humidifier (cold evaporation type) : also known as “no fog type humidifier”, the water is sucked into the filter, and then the fan blows the wet filter, thereby producing moist air. There was no visible spray. It has little effect on the purifier
3, evaporative humidifier (hot evaporation type) : also known as “steam humidifier”, the principle is to heat the water to boiling, and then the water vapor is blown out by the fan, and the water mist is produced, and the water mist is “water vapor”. This kind of humidifier will also have a lot of water vapor generation, which will not only affect the particulate matter sensor of the purifier, but also easily lead to moisture in the filter screen, breeding bacteria and so on.
In fact, many times, we choose air purifiers will be more biased to the brand, the performance parameters of the machine, such as: CADR value and CCM value is high, what is the mute effect (will the children’s room or bedroom affect sleep), handling light is not light (can be portable, what weight, there is no universal wheel), rated power is high (the higher the power, purification energy efficiency value is not high, The more power consumption), features (voice control, APP remote control, optional humidification box, negative ion function), there is also evidence of third-party testing reports, that is, the purification efficiency is verified by third-party testing institutions, but often ignore the purification method and principle. Usually, when we evaluate and analyze multi-product air purifiers, we can analyze and judge from three dimensions, such as: purification methods and principles, including not limited to negative ion purification technology, catalyst purification technology, amino acid purification technology, activated carbon adsorption technology, electrostatic purification technology, etc. Third party inspection and testing reports, including but not limited to China Metrological accreditation mark CMA, laboratory accreditation mark CNAS, International mutual recognition testing mark ILAC-MRA, etc. Relevant performance parameters, including but not limited to CADR value, CCM value, silent noise, use area, light handling, features, rated power, etc.
