Product Overview
The disposable bacterial and viral filter protects the breathing circuit and the patient from cross contamination, without the moisture return of an HMEF. Filtration is BFE 99.9 to 99.999 percent and VFE 99 to 99.99 percent, with 32 ml dead space, a 250 to 1500 ml tidal volume range, 22M/15F-15M/22F connections and a weight of 25 plus or minus 3 g. A gas monitoring luer port with retainer strap is fitted.

Key Benefits
- BFE up to 99.999 percent and VFE up to 99.99 percent filtration
- Low resistance at under 1.2 cmH2O at 30 LPM and under 2.6 cmH2O at 60 LPM
- Luer port with retainer strap for gas monitoring without opening the circuit
- 22M/15F-15M/22F connections fit standard circuits
Problems It Solves
- Cross contamination between patient and ventilator circuit
- Filters whose resistance loads a spontaneously breathing patient
- Opening the circuit to sample gas
Who It Is For
- ICU and anaesthesia department buyers
- Breathing circuit kit assemblers
- Distributors supplying infection control respiratory consumables
Application Scenarios
- Mechanical ventilation where an active humidifier is already in use
- Anaesthesia breathing circuits
- Circuit protection during transport ventilation

Customisation Options
- Carton quantity on request
- Own-label packing and printing
- Supply alongside the HMEF range where both are required
Use Guide
- Confirm the patient tidal volume falls in the 250 to 1500 ml range
- Fit between the patient connection and the circuit using the 22M/15F-15M/22F ports
- Use the luer port for gas monitoring rather than opening the circuit
- Change the filter per unit protocol or sooner if secretions load it
Compared With Other Options
| Heat Moisture Exchanger Filter | The HMEF adds moisture return, so it can replace an active humidifier. This BV filter provides filtration only, for circuits that already have humidification. |
