Disclosed herein is an air conditioner that determines the replacement time of a filter. The air conditioner may include a filter for filtering particles in air that is suctioned, a first camera disposed so as to monitor the state of the filter, and a controller for analyzing an image of the filter acquired from the first camera through a deep neural network model trained using machine learning in order to determine a pollution level of the filter. The controller may be configured to determine the time at which the filter is to be replaced based on at least the pollution level of the filter, and may be further configured to use information collected from other electronic devices in an Internet-of-Things environment connected as a 5G communication environment in order to determine the time at which the filter is to be replaced.

Included herein are filtration systems that can proactively pulse clean filter elements in response to anticipated changes, such as anticipated changes in filtration performance or anticipated changes in filtration system demand. In an embodiment, a filtration system is included having a filter element mount for a filter element, a compressed gas supply, and a valve, wherein opening the valve results in a pulse of gas directed at the filter element. A control circuit can control the valve. A communications circuit can receive data related to an anticipated change, such as data regarding an anticipated change in filtration performance and/or data regarding an anticipated change in filtration system demand. The control circuit can execute operations based on the anticipated change data such as adjusting a pressure drop threshold and initiating proactively opening the valve in the absence of a pressure drop threshold being crossed. Other embodiments are also included herein.

A smart mask includes a face covering, an attachment member, one or more sensors, and a controller. The face covering is configured to cover a face area of a wearer. The attachment member is configured to attach the face covering onto the face area of the wearer. The one or more sensors comprises an air quality sensor configured to obtain first data associated with nearby air quality or a breathing pattern sensor configured to obtain second data associated with the wearer's breathing pattern. The controller is configured to process the first data associated with nearby air quality to identify a current air quality, or process the second data obtained by the breathing pattern. In response to determining that the current air quality is worse than a predetermined threshold, or identifying a particular breathing pattern, the controller is configured to generate a notification, notifying the wearer.
