To clean it the plastic canister pops out and you can empty it without getting the dust all over the place. The filter comes out of the back end, the filter is made out of foam rubber which I can wash. The filter takes a few days to dry so you need to plan ahead. Not sure how to replace the foam filter, when I search for a replacement filter on Amazon I could not find it.
You can find it on Amazon by following this link.
