I don’t like the idea of breathing in dust while running my machinery any more than the next guy (er, woodworker.) A few years ago, when we finally stopped using our last box fan, I hid it away, having an idea to re-purpose it down the road. So a few weeks ago, I decided to take another step towards a safer shop. I dug out the fan and cleaned it up. After checking that it still ran OK, I went out and bought one of those filters for forced hot air heating systems and installed it on the ‘sucking’ side of the box fan. This particular filter, 20×20 inch in my case is disposable, but I plan on investing in one that can be cleaned and reused (up to ten years according to the product info!)
The filter is simply taped onto the frame of the fan with duct tape. When upgrade, I might make a proper wooden frame to ease the removal of the filter for cleaning. In any case, I have noticed a difference in the air quality of my shop after doing dust-making operations. I’ve also noticed less need to dust things off that aren’t even my tools.
