The invention discloses a
filtration type
air purifier. The
filtration type
air purifier comprises a base, vent holes, air inlet holes, a motor, an outlet, a fan, an
activated carbon filter screen and an
HEPA (high-efficiency particulate air) filter screen. The base is a
hollow cylinder, the bottom of the base is provided with the vent holes, and the fan is mounted beside the vent holes and driven by the motor. A plurality of filter screen
layers are arranged in the base and include a first filter screen layer, a second filter screen layer, an
HEPA filter screen layer and an
activated carbon filter screen layer. The screen
layers are provided with fine and dense through holes. Filter screen films are correspondingly mounted on the filter screen
layers and cover the through holes. A controller is mounted in the base and electrically connected with the motor, and the controller is connected with a
mobile phone through
Bluetooth signals. By adoption of various filter
screen techniques, effective
filtration of
solid particles and
gaseous pollutants in air is realized, so that
indoor air purification can be achieved; an equipment operation process can be controlled by the
mobile phone, and real-time purification starting is realized.
