To improve the way of cleaning current polluted air, removing dust from air in an air cleaner and deodorizing it while avoiding the problem on a conventional disclosed construction with a negative ion generator and a positive ion generator combined for forcibly generating negative ions from a tourmaline coated surface to clean air that positive ions are not sufficiently generated because the way of cleaning adopts planar contact between air and tourmaline particles.

A purifying sheet containing tourmaline and zeolite is mounted in an air cleaner chamber at an intake port of a vehicular air cleaner mechanism for enlarging a range of contact among a deformed portion of the purifying sheet, the tourmaline and the zeolite on the deformed portion/a sheet body and air in the air cleaner and developing the functions of negative ions generated by the tourmaline particles, electrolysis, exchange of cation of the zeolite, catalysis and adsorption. The removal of dust from air in the vehicular air cleaner, deodorization and sterilization thereof or cleaning of air are allowed.
