Apparatus and system for air cleaning

Abstract

An air filtering and treatment apparatus (10), the apparatus (10) including: a housing (12) having an air inlet (14), an air outlet (16), an air passageway (24) between the inlet (14) and outlet (16),and a fan (18) arranged to urge air through the air passageway (24) between the air inlet (14) and the air outlet (16), wherein the housing (12) includes filter (20) arranged to filter air passing through the air passageway (24), and a receptacle (26) located toward the air outlet (16) relative to filter (20). The receptacle (26) is adapted to hold treatment composition (22) such that an evaporable vapour associated with the treatment composition (22) is able to accumulate in a headspace (41) of the receptacle (26), the headspace (41) including at least one aperture (36). The air passageway (24) may be shaped such that air flows substantially perpendicularly past the at least one aperture (36) of the receptacle (26) such that a pre-determined amount of the evaporable vapour is entrained into the filtered air released from the air outlet (16). A system (100) and method are also disclosed.

Description

[0001] cross reference [0002] This application is based on and claims priority from Australian Provisional Patent No. 2016905336 filed on 22 December 2016 and Australian Provisional Patent No. 2017901850 filed on 17 May 2017, the contents of which are adopted References are incorporated into this application. technical field [0003] The present invention relates to a device and system for air purification, especially for the filtration, treatment or disinfection of indoor air. Background technique [0004] Air quality, especially indoor air quality, can be affected by dust, pet dander, odors, airborne organic matter (eg, mold, airborne pathogens). Therefore, various types of indoor air filter devices have been proposed. [0005] One type of air filtration unit consists of a housing with a fan that draws air in through the center of the rear and forces the air through the filter and out through a grille at the top of the housing. The filter may be a HEPA (High Efficienc...

AI Technical Summary

Problems solved by technology

[0008] However, a problem with this type of air filter is the limited lifespan and efficacy of the air freshening or disinfecting substances, and the ease of use by the user, such as replenishing these substances

Another problem that exists is related to the control of the emission of substances, such air filtration devices may include relatively complex devices to control the emission of substances
