It should be noted here that the air inlet filter assembly is arranged close to an air inlet of an air purifier, and the primary filter screen 100 and the composite filter screen 200 are sequentially arranged along the air inlet direction, that is, along an air flow direction. The primary filter screen 100 can primarily filter the air to adsorb part of the pollutants in the air, and the composite filter screen 200 can further filter the air filtered by the primary filter screen 100 to adsorb another part of the pollutants in the air. Therefore, the filtering effect of the air inlet filter assembly can be guaranteed and improved.
Among them, the activated carbon layer 220, through at least the activated carbon layer 220, can filter toxic and harmful gases with a molecular diameter smaller than the micropore diameter of the activated carbon. Based on this, the filtering effect of the composite filter screen 200 can be improved, thereby helping to improve the filtering effect of the air inletfilter assembly.
It should also be noted here that after the air inlet filter assembly is used for a period of time, a large amount of pollutants will accumulate in the primary filter screen 100 to form attachments. At this time, the primary filter screen 100 can be removed from the composite filter screen 200. Then, the primary filter screen 100 is cleaned with rinsing liquid such as clean water to remove the attachments attached to the primary filter screen 100, and after the primary filter screen 100 is dried, the primary filter screen 100 can be reconnected to the composite filter screen 200 so as to reuse the primary filter screen 100, the service life of the air inletfilter assembly can be correspondingly prolonged on the basis of ensuring the filtering effect of the air inlet filter assembly, that is, on the basis of ensuring the performance of the air inlet filter assembly.
It should also be noted here that when the attachments of the primary filter screen 100 are not fully cleaned or the primary filter screen 100 is damaged, the primary filter screen 100 can also be replaced to further prolong the overall service life of the air inlet filter assembly and reduce the replacement costs.
In summary, the air inlet filter assembly provided by the embodiment of the present application first filters the air through the primary filter screen 100 to absorb part of the pollutants in the air, and then further filter the air filtered the primary filter screen 100 through the composite filter screen 200 to absorb another part of the pollutants in the air, which can ensure and improve the filtering effect of the air inlet filter assembly. In which, the activated carbon layer, through at least the activated carbon layer, can filter toxic and harmful gases with a molecular diameter smaller than the micropore diameter of the activated carbon, thereby ensuring and improving the filtering effect of the air inlet filter assembly. In addition, after the air inlet filter assembly has been used for a period of time, the primary filter screen 100 can be disassembled from the composite filter screen 200, and the attachments on the primary filter screen 100 can be cleaned with rinsing liquid to reuse the primary filter screen 100. Based on this, the service life of the air inlet filter assembly can be correspondingly prolonged on the basis of ensuring the filtering effect of the air inlet filter assembly, that is, on the basis of ensuring the performance of the air inlet filter assembly; even when the attachments attached to the primary filter screen 100 are not fully cleaned, or the primary filter screen 100 is damaged, the primary filter screen 100 can be replaced to further extend the overall service life of the air inlet filter assembly and reduce the replacement costs.

The HEPA high-efficiency filter layer 210 has a effective filtration rate of 99.7% for 0.3 microns pollutes, and 99.99% for larger particles.
Therefore, by adopting the above solution, particulate pollutants such as smoke, dust, bacteria, etc. can be efficiently and reliably filtered through the HEPA high-efficiency filter layer 210, thereby helping to improve the filtering effect of the composite filter screen 200, thereby helping to improve the filtering effect of the air inlet filter assembly.
Please refer to FIG. 1, FIG. 2, and FIG. 3, in this embodiment, the composite filter screen 200 at least includes an antibacterial paper layer 230.
By adopting the above solution, bacteria harmful to human health can be killed by the antibacterial paper layer 230, and the effect of sterilization and antibacterial can be achieved. Based on this, the filtering effect of the composite filter screen 200 can be improved, thereby helping to improve the filtering effect of the air inlet filter assembly.
Please refer to FIG. 1, FIG. 2, and FIG. 3, in this embodiment, the composite filter screen 200 includes a HEPA high-efficiency filter layer 210, an activated carbon layer 220 and an antibacterial paper layer 230 that are sequentially stacked along the air inlet direction.
By adopting the above solution, the composite filter screen 200 can filter particulate pollutants such as smoke, dust and bacteria through the HEPA high efficiency filter layer 210 efficiently and reliably, then filter through the activated carbon layer 220 with a molecular diameter smaller than the micropore diameter of activated carbon, and finally, the antibacterial paper layer 230 kills bacteria that are harmful to human health. Based on this, the composite filter screen 200 can form a progressive filtering effect, thereby helping to improve the filtering effect of the air inlet filter assembly.
Please refer to FIG. 1, FIG. 2, and FIG. 3, the present application also provides an air purifier including an air inlet filter assembly.
By adopting the above solution, on the one hand, the air purifier can better filter and purify the air through the air inlet filter assembly with better filtering effect, thereby helping to improve the air quality output therefrom; on the other hand, with the primary filter screen 100 can be disassembled and cleaned, the air inlet filter assembly can be reused and the service life can be prolonged, which to a certain extent also helps to extend the service life of the air purifier.
