The filter itself is an Austin Air FR400.
Filter dimensions: 14" o.d., 7.5" i.d. x 14.5" tall.
Overall dimensions: 16.5"W x 16.5"D x 3'H
This can filter a large space. This is a DIY setup with a duct fan, and a variac for speed control (smooth, quiet operation). I made the cabinet with some scrap wood. Maybe you can improve upon that.
I am unsure on filter life. It runs well. I am downsizing. I made it during the pandemic.
