Abstract
A filter system includes a source of clean filter media adjacent a channel through which fluid passes. The filter media is automatically advanced from the source to the channel and eventually to a sealed container adjacent the channel. The filter media is automatically advanced through the channel, where it is replaced with clean filter media in the channel. A controller controls the advancement of the filter media based upon time or based upon a current condition of the filter media.
