The heavy duty pre-filter set is a wise investment that will save money over the life of your Smokemaster C-12 Air Cleaner.
If you've got a tough indoor pollution problem, then you need heavy duty pre-filters. Heavy duty filters will help protect the cell more diligently than standard pre-filters because they capture more particles.
Heavy Duty pre-filters are constructed with a denser, more rigid, sturdy metal. These heavy duty filters rarely need replacing because they don't degrade and won't detach from the frame due to washing and usage. Their construction keeps them from shedding aluminum “hairs” up in to the electronic cells which can cause sparking.
Heavy duty pre-filter set includes 2 filters. (C-12 requires 2 filters.)
