An information processing method includes: obtaining location information indicating an installation location of an appliance, and user information indicating a first user linked to the installation location; obtaining log information indicating an operation performed by the appliance, and receiver information indicating a second user that receives presentation information; determining, when detecting a change in a state of the first user by reference to the log information and determining that the first user does not match the second user, the presentation information to be presented to the second user in accordance with the change in the state; and outputting the presentation information determined.

A method to predict the lifespan of an air filter including providing pressure sensors in a device having an air filter and a fan to drive air through the air filter, one pressure sensor located on an intake side of the fan and one pressure sensor located on an outflow side of the fan, periodically calculating a static pressure drop across the fan, storing the static pressure drop daily; calculating an average pressure drop, calculating a cumulative particle loading on the filter, comparing the cumulative particle loading with a pre-determined maximum particle loading for the filter, and determining if the filter needs to be changed is provided.

An air purifier including a fan having a plurality of fan speeds; a filter, wherein the fan draws air through the filter; a user interface in communication with a control system; wherein upon activation of the control system, the control system identifies an initial air quality index (AQI) based upon a geographic location of the air purifier, a room size based upon the type of room in which the air purifier is placed, and identifies a fan speed set by a user through the user interface, and determines a target air quality index achievable in thirty minutes of fan operation is provided. Further provided is an air purifier capable of predicting and updating time to achieve a target air quality and a target air quality based on a number of environmental factors.

A humidifier/dehumidifier device is disclosed herein. The humidifier and dehumidifier both, respectively, evaporate water from and condense water into a shared (same) water storage container. The device is fitted with an air intake and at least one air outtake. In embodiments of the technology, one or more of the air intakes receives air from outdoors. One or both of an indoor and/or the outdoor intake is used to receive air based on a determination that an indoor and outdoor humidity and temperature is most efficient to achieve a desired indoor humidity or temperature.
