PURPOSE: A car air cleaner improves combustion efficiency of a car engine and has a fuel reduction effect. CONSTITUTION: A car air cleaner comprises a housing unit (110), a guide unit (120), a primary filtering unit (130), a secondary filtering unit (140), and a main filtering unit (150). The housing unit forms a cylindrical main housing (111), and comprises a filtering housing (113) inserted into the main housing. The guide unit includes a guide groove (121) inside the filtering housing of the housing unit, and an inflow path (122) is formed in the guide groove. The primary filtering unit forms a casing (131) in which oil is filled in a lower part. The primary filtering unit forms a porous plate (132) in a front side of an upper part of the casing. The primary filtering unit forms a metallic mesh (134) on the rear side of the upper part of the casing. The secondary filtering unit filters air which passes through the primary filtering unit again. The main filtering unit filters air which passes through the secondary filtering unit through a strainer of the main filter. |
