Blog: Small Shop Essential – How To Make a Low Cost Air Cleaner By: I Build It

This is an easy to make, compact and low cost way to effectively clean the air in your small shop. I bought the parts for mine for less than $100, and that includes the fan and the two filters. I mounted it on the ceiling pointing down toward my table saw to pump a supply of fresh clean air in while I’m making a cut. And I made it so that it will turn on when I turn on the lights in my shop, so it will be working continuously to filter and move the air in the shop.
