The invention discloses a turbid gas filtered type air purifier. The turbid gas filtered type air purifier comprises a shell, wherein a gas inlet and a air outlet are separately formed in the top end of the left side and the bottom end of the right side of the shell, a top fixing hood and a bottom fixing hood are separately mounted at the internal upper and lower ends of the shell, an inner composite filter screen is mounted at the internal left side of the top fixing hood, an HEPA filter screen, a dust filter screen, a nylon mesh and a metal filter screen are sequentially mounted inside a fixed tube from top to bottom, and a blower is mounted at the internal right side of the bottom fixing hood. According to the turbid gas filtered type air purifier, an activated charcoal plate is used for adsorbing off odors from turbid gas in a manner that the top fixing hood, the fixed tube and the bottom fixing hood are matched with one another, the turbid gas is further filtered through the HEPA filter screen, the dust filter screen, the nylon mesh and the metal filter screen when the turbid gas passes through the interior of the fixed tube, and thus, the turbid gas filtering effect is improved; meanwhile, the overall design is of an upper-middle-lower distribution and is relatively low in space usage, so that the use requirements of people are met.
