Do you ever wonder what the fine sawdust is doing to your lungs? You should! Shop air quality, especially in a woodshop is an important safety hazard to understand. In this video we review and install the WEN 3410 filtration unit in my shop. This unit not only helps protect your lungs but goes a long way to keeping fine sawdust from accumulating everywhere in your shop. Included in this video is also a recommendation for a mask which I like to use as a second layer of protection.
