Novel compressed air filter

The utility model relates to the technical field of gas treatment, in particular to a novel compressed air filter which comprises a supporting seat, six supporting columns are fixedly connected to the bottom end of the inner wall of the supporting seat, limiting grooves are formed between the adjacent side faces of the six supporting columns, and every two limiting grooves form a group. And two filter elements are placed among the six groups of limiting grooves. Compared with the prior art, the air purifier has the advantages that the limiting grooves are formed between the adjacent side faces of the six supporting columns, every two limiting grooves form one group, the two filter elements are placed among the six groups of limiting grooves, and the structures of the filter elements are completely the same, so that when the filter elements are replaced, the six filter elements close to the air inlet pipe are taken out, and the replacement efficiency is improved. Then the remaining filter elements are close to
