1. Patients with arthritis and diabetes should use air humidifier with caution. Damp air will aggravate arthritis and diabetes, so it is generally not recommended for such patients. If such patients really need to use humidifiers to reduce the occurrence of some respiratory complications, they should consult with the specialist to determine the appropriate humidity to stabilize the original disease.
2. Clean the humidifier regularly according to the instructions. If the humidifier itself is unsanitary, bacteria will float in the air with water vapor, which will also cause harm to human health.
3. Do not directly add tap water to the humidifier. Because tap water contains a variety of minerals, it will damage the evaporator of the humidifier, and the water alkali contained in it will also affect its service life. Chlorine atoms and microorganisms in tap water may be blown into the air with water mist to cause pollution. If the hardness of tap water is high, the water mist sprayed by the humidifier will produce white powder and pollute the indoor air because it contains calcium and magnesium ions.
