Method of determining replacement time of filter and air conditioner that determines replacement time of filter

This invention describes an air conditioner that can tell you when its filter needs to be replaced. It does this by using a camera to take pictures of the filter, then a computer analyzes these images to figure out how dirty the filter is. The system then decides the replacement time based on the filter's dirtiness, and potentially also considers how much the air conditioner has been used or the local air quality.

Why it matters: Since 2019, the widespread deployment of 5G networks and advancements in edge AI for image processing have made real-time data collection and on-device machine learning more feasible and cost-effective for this application.
