摘要： An air purification apparatus and air purification method is disclosed. Air to be purified is drawn into an air purification unit for purification by a negative pressure, wherein the negative pressure region is created by a fan blower, and the air to be purified does not pass through the fan blower to prevent the fan blower being contaminated by the pollutants which presented in the air to be purified. With the present invention, the lifespan of the fan blower can be extended, and the fire alarm risk caused by accumulated pollutants can be decreased. The fan blowers with lower power consumption can be used to achieve the beneficial effects of energy saving and noise reduction.

摘要： An air purification device comprising: air flow path adjuster (10) and a primary filter (30), the said air flow path adjuster (10) able to change the path of the air flow within the air cleaning device, so that to enable the air bypassing or passing through said primary filter (30). The air purification device can be improved air cleaning efficiency.
