Making an Inexpensive Air Cleaner for Your Shop

In this I Build It video, John shows how he made a very simple and inexpensive air cleaner for a small woodshop.

The air cleaner was made from little more than a small fan, a piece of duct piping, some scrap ply, and a several shop vac air filters.

I love the way that it is designed so it can be expanded via a threaded rod that holds the filters in place.
