The utility model belongs to the technical field of designing and manufacturing of pipeline type air filters, and particularly relates to a pipeline type air filter. The pipeline type air filter is installed on a fresh air ventilator and is used for filtering the air entering the indoors. A pipe body is formed in a sleeved mode, and three filtering pieces are arranged inside an inner inserting pipe. Sponge gaskets are arranged at two ends of the filtering pieces and a metal net is arranged at the two ends of each filtering piece. The pipeline type air filter can be used for replacing a ventilation pipe of an existing fresh air ventilator, and is communicated with the outdoors when installed on a wall. Due to the fact that the three filtering pieces are arranged inside the pipe body, the air entering the indoors can be processed to a certain extent before entering the pipeline type air filter, is further processed after entering the pipeline type air filter, and then is released to the indoors, so the exchanged indoor air is fresher. The pipeline type air filter solves the problem of use of the ventilation pipe of the existing fresh air ventilator. Besides, the pipe body can be assembled and can be stretched out or drawn back according to the indoor space, so that convenience is brought to construction and installation.
