The present invention aims to provide an aldehyde scavenger which has excellent aldehyde scavenging properties and yields a resin composition with excellent moldability (mold fouling resistance) when added to a resin. The present invention relates to an aldehyde scavenger containing at least one of: (1) a copolymer (A) containing a (meth)acrylamide (a) and an acid group-containing unsaturated monomer (b) as constituent monomers; and (2) a mixture containing a (co)polymer (B) and a (co)polymer (C), the (co)polymer (B) containing the (meth)acrylamide (a) as a constituent monomer but not containing the acid group-containing unsaturated monomer (b) as a constituent monomer, and the (co)polymer (C) containing the acid group-containing unsaturated monomer (b) as a constituent monomer but not containing the (meth)acrylamide (a) as a constituent monomer.

A device for air purification, incorporated into a vehicle, which comprises a case, fixed to the outside of the vehicle and having a longitudinal duct through which air passes, the air entering impure through at least one opening located in the front part, with respect to the direction of travel of the vehicle, and exiting through at least one opening located in the rear part under the suctioning effect of at least one fan disposed in the opening. From the inlet to the outlet, the air purification device successively includes the following devices: a photocatalytic reactor; a reverse microwave; an activated carbon filter; and a HEPA filter, just before the fans located in the outlet conduit.
