HEPA filter for DD-MINI Portable Downdraft

High-efficiency particulate arrestance (HEPA) filters offer hospital-grade filtration (99.97% efficiency of 0.3 micron particles), allowing indoor-venting in most applications. These HEPA filters are unaffected by moisture, as the micro-glass paper construction is waterproof. HEPA filters are recommended in the following applications:

• Welding stainless steel, galvanized steel, high-carbon steel
• Presence of hexavalant chromium

The HEPA filter for the DD-MINI occupies all 4-inches of capacity in the filter compartment, and acts as a primary filter.
