BVF™

• Microbes as small as sub-micron size trapped.
• Nanofibre medium creates electrostatic filtering
• 99.99% cross-contamination efficiency
• Low expiratory flow impedance
• Unique, comfortable 25mm mouthpiece (other sizes available)
• Tested and efficient at high flow rates
• Protects your test subject and your equipment
• Fully disposable for complete hygiene

Bacterial Viral Filters (BVF) protect both the patient and your equipment during pulmonary function testing. Static attraction technology allows even sub-micron sized microbes to be trapped.

Our BVF's now have a reduced effective dead-space of 65mL with 99.99% cross-contamination efficiency and low back pressure.

The square shape allows efficient use of high-technology and expensive filter medium, resulting in less waste and therefore, a lower price.

Vitalograph BVF's come in a variety of sizes, including versions designed specifically for Sensormedics and Jaeger units. Adapters are available to fit most other models.

SafeTway® One-way Valve Mouthpieces

• For use with peak flow meters and spirometers
• One-way valve prevents accidental inhalation
• Completely disposable
• A low cost alternative to BVF for expiratory testing
• Pediatric version available

The low cost, low resistance SafeTway® mouthpiece allows entry of expired air into the measuring system, but not back to the test subject. This simple, yet effective patented design prevents concerns of accidental inhalation of pathogens.

The SafeTway is an inexpensive alternative to the bacterial viral filter for expiratory only testing. It fits most pulmonary function test equipment, including peak flow meters. An adapter may be required.

The Mini SafeTway with a 22mm diameter mouthpiece is also available for pediatric use or for elderly test subjects who have difficulty fitting their mouth properly around the standard mouthpiece size.
