Document Type and Number:
WIPO Patent Application WO/2019/026683
Kind Code:
A1
Abstract:
An air purifier wherein, when installing a plurality of filters that will be positioned close to one another and facing one another, the filters are prevented from scraping against one another. When positioned in a first installation location (P1), a HEPA filter (25) that is a first filter has an upper surface (25a), which is a first surface that intersects an airflow direction. A second filter is positioned in the proximity of the HEPA filter (25), installed in a second installation location (P2) that is in line with the first installation location (P1) in the airflow direction, and the second filter has a second surface facing the upper surface (25a). A guide structure has, for example, a guide groove (101). When the second filter is installed, this sort of guide structure provides support such that the upper surface (25a) and the second surface become substantially parallel, while allowing the second filter to move to the second installation location along a path that is slanted with regard to the second surface.
