When using a humidifier, please adjust the humidity at the right time according to the weather changes and indoor and outdoor temperatures to ensure a comfortable environment. For people with arthritis and diabetes, it is recommended to use air humidifiers with caution to avoid affecting your health. Do not add tap water directly to the humidifier as tap water contains many minerals, which may cause damage to the humidifier's evaporator. In addition, hardened tap water may contaminate indoor air. To maintain good hygiene, clean the humidifier regularly according to the guidelines in the instruction manual. Weekly cleaning is recommended to prevent microorganisms in the water from spreading into the air.
