Avoid using an air purifier near water or volatile flammable materials to prevent accidents. Do not place the humidifier on the air purifier body to avoid co-frequency resonance noise.

Clean the surface of the dust filter with a vacuum cleaner every 1-2 weeks. After using for a certain period of time, use the filter in time to replace the filter to ensure the cleaning effect. It is best to use a desktop air purifier every day for two or three hours, then turn it off.
