[0028] Embodiment 2

[0029] Based on the first embodiment, the preferred embodiment of the filter provided by the present invention is as follows: Figures 1 to 4As shown: the replacement reminder device 4 includes a reminder shell 401, an oil seal 402, and a blockage mark 403.

[0031] In this embodiment, the reminder housing 401 is made of a transparent material to facilitate users to observe the position of the oil seal 402 .

[0032] In this embodiment, a reference air pressure is set inside the reminder housing 401 to cause the oil seal 402 to move upward when the filtering effect of the dust filter cotton 302, the molecular sieve particles 303, and the activated carbon particles 304 deteriorates.
