Apparatus and system for air cleaning

An air filtering and treatment apparatus, the apparatus including:

• a housing having an air inlet toward a base thereof, an air outlet toward a top thereof, an air passageway between the air inlet and the air outlet, and a fan arranged to urge air through the air passageway between the air inlet and the air outlet;
• a sensor configured to measure at least one of air particles and a dew point of the surrounding air environment;
• and
• a controller coupled to the sensor and configured to automatically actuate the fan from an off state to an on state if at least one of the air particles or the dew point levels exceed a predetermined threshold,
• wherein the housing includes a filter located towards the base and arranged to filter air passing through the air passageway, and a receptacle located towards the air outlet relative to the filter,
• wherein the base is removable to allow changing of the filter, and wherein the receptacle includes a removable lid to allow fitting of a removable cartridge containing a treatment composition to the receptacle such that an evaporable vapour associated with the treatment composition is able to accumulate in a headspace of the receptacle, the receptacle including at least one aperture located at a side thereof, and
• wherein an outlet portion of the air passageway is shaped such that air flows past the at least one aperture of the receptacle such that a rate of the evaporable vapour is entrained into the filtered air released from the air outlet.
