Replacement filters. The Antimicrobial Dry Vacuum Cleaner has all plastic components and attachments containing Microban to prevent proliferation of bacteria and viruses. It uses a powerful 1,000 Watt super high speed motor for deep cleaning. While powerful, the Antimicrobial Dry Vacuum Cleaner is also extra quiet for sound sensitive environments such as human and animal hospitals, nursing facilities, and in-home care. Two HEPA filters are used within the Antimicrobial Dry Vacuum Cleaner. The primary filter catches the first of the incoming particles and a secondary filter prevents escape of dust from the carbon brushes. For added convenience an indicator light alerts the operator when to change the bag.
