Why does the PM 2.5 or pollution level indicated by my air purifier increase when I turn on my humidifier next to it?

Ultrasonic air humidifiers work in a simple way: they diffuse water into the air in the form of micro-droplets. By placing your ultrasonic air humidifier too close to your air purifier, you disrupt the PM 2.5 sensor. In fact, the purifier considers the micro-droplets of water invisible to the naked eye as air pollution. Rest assured, under no circumstances does your humidifier diffuse pollutants into your room. The solution is simple, you just need to move the two devices away from each other.
