Abstract: An air purifier includes a housing, a centrifugal fan and an air purifying filter. The fan is substantially centered in the housing. The fan has a rotary shaft extending in a depth direction of the air purifier and a fan inlet port facing frontward. Air suctioned by the fan is blown out in a direction perpendicular to the rotary shaft. The filter is aligned with the fan along the direction perpendicular to the rotary shaft. An air inlet port is disposed in front of the fan so as to communicate with the fan inlet port. When the fan rotates, air is suctioned into the air purifier via the air inlet port. An air outlet port is arranged relative to the filter such that air purified by the filter is blown out of the air purifier through the air outlet port.
