Abstract: A powered room air purifier with a visual indicator of air quality, the visual indicator including: a reflector that defines a forwardly-open-ended reflecting cavity and that includes at least one through-opening in a floor or ceiling of the reflector; at least one diffuser layer that covers the forward opening of the forward-open-ended reflecting cavity; and, at least one LED light source that is positioned within the at least one through-opening, the LED light source and the reflector being configured so that the LED light source is shielded from line-of-sight view along a forward-rearward axis of the powered room air purifier.

Abstract: A cabin air quality monitoring system including a communications interface configured to receive snapshot information representing in-cabin air quality of a vehicle, a memory configured to store the snapshot information received by the communications interface and a processing circuitry configured to batch the snapshot information stored to the memory to form batched snapshot information, to execute, using the batched snapshot information as an input, a trained machine learning model to obtain a model output that includes cabin air filter replacement information, and to transmit, via the communications interface, the model output to computing hardware of the vehicle.
