BOFA Replacement DentalPRO (NEW) Extractor Filter Bags (for new and older 250 and 400 models)

Replacement Filter for the DustPRO 250 and 400 and the new Dental PRO 250 and 400 models. Choice between standard filter or HEPA filters. HEPA stands for high-efficiency particulate air. A HEPA filter is a  mechanical air filter which works by forcing air through a fine mesh that traps harmful particles such as pollen, pet dander, dust mites, and tobacco smoke. HEPA filters are much better for the working environment.
