PURPOSE: To provide a system for purifying gas, a method for purifying gas and a discharge reaction apparatus used for the system for purifying gas capable of effectively removing particular matter and harmful substance such as nitrogen oxide from an object gas to be purified at a low temperature without heating the gas thereby purifying the object gas. CONSTITUTION: The system(1) comprises a gas flow line through which an object gas to be purified flows from an object gas generation mechanism(2), a discharge reaction device(4) provided on a way of the gas flow line, a filter member(5) disposed in the discharge reaction device and having a structure for trapping particular matter contained in the object gas while the object gas passes through the filter member, and a discharge generation device(7) operatively connected to the discharge reaction device to cause electric field inside the discharge reaction device and generate discharge plasma therein.
