This HMEF is a high‑efficiency inline respiratory filter intended for use on ventilator, anesthesia, and breathing circuits to trap bacteria and viruses while allowing accurate CO₂ monitoring through its integrated sampling port. Using this filter helps reduce cross‑contamination risk between patients and equipment while maintaining ventilatory performance and capnography accuracy.

• HEPA bacterial/viral filter with rated efficiency of approximately 99.97% for airborne particles.
• Tidal volume range approximately 150–1000 mL, suitable for many adult and pediatric applications as specified by the manufacturer.
• Standard respiratory connectors: 22 mm OD / 15 mm ID × 22 mm ID configuration for compatibility with common circuits.
• Integrated CO₂ (sampling) port to support sidestream capnography without separate adapters.
• Low dead space around 55 mL and low resistance at typical flow rates.
