Which Phoenix area creekers would be willing to let me come into your shop and measure the level on Indoor Air Quality. I'll provide the instrumentation do the work, all you need to do is provide the shop and the sawdust. I will publish the results on this forum. I would prefer various different type of dust collection so that we can test how effective they are in a real shop environment. I'll be testing for fine dust as well as Total Suspended Particulate. This is your chance to help other creekers breath a little easier. I'll be taking pictures but don't clean up your shops..
