The heavy duty pre-filter is a wise investment that will save money over the life of your Smokemaster X11Q Smoke Eater.
If you've got a tough indoor pollution problem, then you need a heavy duty pre-filter. The heavy duty, industrial strength Polytron pre-filter will protect the cell more diligently because it captures more particles.
