Make sure that the filter (FY2122/00) is properly installed. · The particle sensor is wet. The humidity level in your room is high and causes condensation. Make sure that the particle sensor is clean and dry (see the chapter “Cleaning and maintenance”). · Room size is large or the outdoor air quality is poor. For optimum purification performance, please close the doors and windows when operating the air purifier. · There are indoor pollution resources. For instances, smoking, cooking, incense, perfume or alcohol. · Filter reaches the end of life. Replace the filter with a new one.
