These bags were recommended for my vacmaster beast shopvac. They look like decent quality bags but the first bag I put on ripped at the seam and sealed my HEPA filter which cost more than replacement bags. I cleaned the HEPA filter and installed another bag to see if it was an accident and that bag also exploded. Maybe my vacuum is too "beast" for them, so I wouldn't recommend them for a high-powered vacuum, but they're probably ok for a standard vacuum.
