Sometimes if I load my stove from the front door I get some ashes on the ash lip. And of course there are always some wood chips that fall around the stove. I've been using my shop vac, and of course I always wait several hours before vacuuming any spilled ashes to make sure there are no embers, and I never vacuum unless I'm going to be home for several hours to keep an eye on it. But I get a lot of ash dust coming out of the vacuum, even when using a paper filter. I've seen some "Ash Vacuums" for sale, but they aren't cheap. Just looking for some suggestions. Thanks!
