Why is the indicator light still red on my AROEVE MK04 after I replaced the filter?

The red light may be due to dust accumulation on the sensor lens, preventing accurate air quality measurement, or because the air quality is poor. After replacing the filter, place the AROEVE Air Cleaner in a clean space and let it run for 6 to 24 hours. The sensor should automatically return to a blue light.
