Go to Lowe's and get a filter designed for concrete dust. They are about $30.00 but worth it. You can knock them out, wash them and reuse over and over. I used these when I was installing car lifts. We had to drill lots of holes. I'm sure they would work great for ash, but I haven't tried it yet. Now that I have a UDS, I'm sure I will.
