[0002] Air purifiers, also known as air cleaners or air fresheners, can absorb, decompose or transform various air pollutants, effectively improving air cleanliness. Existing air purifiers often have only one fence at the air inlet, behind which is the air inlet of the air purifier body. The fence only serves to prevent people, especially children, from touching the components inside the air purifier, especially the filter, and cannot effectively disperse and guide the incoming air, which can easily lead to dust accumulation on the filter at the air inlet, affecting the effect of the pre-filter. Moreover, it is currently difficult to replace the filter of an air purifier.
