Abstract
A buried type air purifier including a main body to be buried in a buried space through a buried opening provided on a boundary surface between a use space and the buried space, the main body having an intake passage and a discharge passage which take in and discharge air, respectively; a fan to guide air of the use space along the intake passage and the discharge passage; and a filter to filter the air. The main body includes: a first main body part having a fan accommodating part to accommodate the fan; and a second main body part having a cross sectional area, which is parallel with the boundary surface, being smaller than the first main body part, where the second main body part is formed to pass the intake and discharge passages through which the air guided via the fan accommodated in the fan accommodating part passes.
