Smart Reminder for Filter Replacement

When the filter accumulates 2,000 hours of use, the indicator light will automatically light up. After fitting a new filter, just press and hold the filter replacement button to reset the timer and turn off the reminder light.

Simple Filter Replacement Process

First, locate the filter compartment at the bottom of the device, which can be opened without tools. Next, release the fixing buckle or rotate the locking mechanism, and carefully remove the old filter. Before installing the new filter, unseal it immediately (premature exposure will reduce its effectiveness), then align it with the internal guide rails and insert it firmly. Finally, close the filter compartment tightly until it is completely sealed, ensuring there are no gaps to prevent unfiltered air from leaking.
