NOVELTY - The purifier has a fan cavity filled with copper, through-hole copper or through-hole foam copper. A fan rotating blade impacts virus or bacteria gas to inactivate the copper, the through-hole copper or the through-hole foam copper and enter the virus or bacteria gas to the copper, the through-hole copper or the through-hole foam copper. The fan rotating blade inactivates the virus or bacteria gas in the copper, the through-hole copper or the through-hole foam copper for absorbing noise and releasing non-live virus or bacteria gas. An inner cavity of a fan is arranged with the copper, the through-hole copper or the through-hole foam copper. The fan is externally connected with an electric heater. USE - Virus or bacteria killing-type air purifier for use in a hospital, a scientific research unit, an office space and a large air area. ADVANTAGE - The purifier can reduce wind resistance of an outer arc surface and increase fan air quantity by combining an arc surface outer curved surface fan blade and an air inlet curved fan blade, thus reducing noise of the fan.
