efficiency filtration: HEPA 99.97% filtration at 0.3 microns captures fine dust, smoke particles, pet dander, and everyday debris before they recirculate. Helps keep indoor air cleaner and maintains steady airflow. Dense pleats provide a generous media area for strong pickup on carpets and hard floors while reducing filter changes during heavy cleaning cycles. Precise compatibility and fit: Designed to match Electrolux UZ930, Nilfisk GD930, and Euroclean GD930 canisters (crossreference 1402666010). Seats correctly in the housing without modifications. Dimensions are tuned for these models to prevent leaks and contain fines, delivering consistent cleaning performance with every pass. Built for commercial workloads: Made for frequent use in offices, hotels, schools, retail spaces, and warehouses. Sturdy frame and tightly packed media resist collapse under strong airflow and heavy dust loads, delivering consistent filtration during long shifts. Helps protect your vacuum motor and maintain stable pickup when cleaning large areas and moving between rooms. Quick, tool replacement: Replacement takes seconds—lift out the used filter, drop in the one, and close the cover. No tools, no complicated steps, and no mess. Fast changeover minimizes interruptions to cleaning schedules, allowing crews to move between rooms and floors without lengthy maintenance. Practical use scenarios: Hotel lobbies and conference spaces after events, where dust and debris accumulate quickly. Daily cleaning in schools and offices with foot traffic and pet dander. Retail floors and warehouses with heavy dust loads and frequent turnover, needing reliable suction over long shifts.
