It should be noted that, in this embodiment, the first preset threshold and the second preset threshold are both air particulate matter content values, and the first preset threshold is greater than the second preset threshold.
The implementation principle of the first embodiment is as follows: when the novel air filter is used, indoor air is pumped into the case 1 by the exhaust fan 3 in the case 1, when the air passes through the meltblown 5 from the air inlet 101 of the case 1 and enters the case 1, the meltblown 5 filters the air, most particles (including viruses and bacteria including new crown viruses and particles more than 0.3 micron) in the air are blocked on the surface of the meltblown 5, the filtered air is blown out through the air outlet 102 of the case 1, and the blown air is fresh air. When the meltblown fabric 5 reaches the replacement condition, the winding roller 7 is driven to rotate by the driving motor 11, the meltblown fabric 5 is wound by the rotating process of the winding roller 7, so that the contaminated meltblown fabric 5 is wound, and meanwhile, in the winding process, the meltblown fabric 5 of the unwinding roller 6 is pulled to be unwound until the new meltblown fabric 5 covers the air inlet 101 of the case 1, so that the meltblown fabric 5 is replaced.
