Embodiment 1
[0028] Embodiment 1, with reference to Figure 1 to Figure 3 as shown,
[0029] This embodiment provides a filter element 100 for filtering air, such as figure 1 As shown, the filter element 100 for filtering air includes a housing 110, the housing 110 has an inlet end 101 and an air outlet end 102, and the housing 110 is sequentially provided with a primary filter layer 120, a microfiltration layer 130 and a nanofiltration layer 140 . What needs to be explained here is that, figure 1 The gaps between the primary filter layer 120, the microfiltration layer 130 and the nanofiltration layer 140 in the middle filter element are not used as the standard when the actual filter element is manufactured, but are just for example of different layers of the filter element.
[0030] The primary filter layer 120 is arranged near the air inlet end 101 , and the nanofiltration layer 140 is arranged near the air outlet end 102 . Among them, the primary filter layer 120 is used to support...
