Made mine a long time ago out of a trashed kitchen cabinet. Has worked perfectly and never let me down. My wife made the curtain out of a scrap of sheer fabric. I paint the model then close the curtain and leave the exhaust fan on to aid in drying. The curtain catches any and all dust. My wife comes up and takes it off every once in a while and throws it in the wash then brings it back up. Have used 2 filters per year at $2.50 each.

Whatever works. The most expensive is not necessarily the best.
