The pre-filters are the first stage in any air cleaner. The purpose of a pre-filter is to capture larger, denser pollutants, such as dust, lint or hair before they can enter the main filter area. The Smokeeter SE-40 pre-filter evenly distributes the air across the ionizing section to maximize efficiency.
