The controller 552 may further monitor a dampness of the moisture absorbent material 558 to determine when it should be replaced.
Optionally, the enclosure 500 also comprises a filter 560 to filter debris. In one embodiment, the filter 560 is a HEPA filter. The filter 560 may be disposed on an upper base plate of the frame 534, a lower base plate of the frame 534, or the frame 534. The activity of the filter 560 may be controlled by the controller 552. For example, if a detected level of debris is high, the controller 552 may increase an activity level of the filter 560 (e.g. a heavy-duty mode). In contrast, if a detected level of debris is low, the controller 552 may decrease an activity level of the filter 560 (e.g. a light-duty mode). As another example, the filter 560 may be disposed at an inlet of the first vent 554. The controller 552 may further monitor a condition of the filter 560 to determine when it should be replaced.
