Hi! I've got a Mountain Air carbon filter 300mm x 800mm. I'm wondering what is the average life span of a CF that is continuously scrubbing hot dank. Also does it preserve the filter at all to switch it off at lights off/ not in use? I've never used one long enough to find out
TIA and if this info is already posted elsewhere just point me the way
