To provide an air cleaner and an air cleaning system capable of efficiently cleaning air by causing photocatalytic action utilizing air flow.
An air cleaner A is provided inside a duct 3 where air generated by a power source flows. The air cleaner A includes: a photocatalyst filter 4 provided in a flow path of the air; a piezoelectric element 6 capable of converting the flow of the air into electric energy; and a light emitting diode 5 to which power is supplied from the piezoelectric element. The light emitting diode 5 is fixed at such a position that a light beam radiated from the light emitting diode 5 can reach the photocatalyst filter 4. Also, the air cleaning system includes the air cleaner A, and the power source capable of generating the flow of the air.
