7. A submicron-level gas purification and treatment device as described in claim 2, wherein, The distance between any two adjacent steering guide holes (314) is greater than the diameter of the intake passages (3141) and the exhaust passages (3142).

8. A submicron-level gas purification and treatment device as described in claim 1, further comprising a control device (50) disposed beside the fluid pressurization device (20), wherein, The control device (50) is electrically connected to the fluid pressurization device (20).

9. A submicron-level gas purification and treatment device as described in claim 8, wherein, The control device (50) can control the output speed of one of the fluid pressurizing devices (20).

10. A single-cell filter chamber device (200), comprising: A housing (60) includes a single air inlet (61), a single air outlet (62) and a single drain outlet (63). A filter (31) is provided inside the housing (60). The filters (31) are sequentially arranged from top to bottom, including an end filter unit (311), at least one intermediate filter unit (312) and a flow guide bottom cover unit (313) which are fixedly connected to each other. Both the end filter unit (311) and the relay filter unit (312) have a flat hollow structure (317) and an air outlet (318).
