BVF™

• Bacterial and viral filter even sub micron size
• Nanofibre medium creating 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

Vitalograph has taken the successful BVF (Bacterial Viral Filter) and developed a new, improved version ensuring complete confidence in this highly efficient disposable filter.

Static attraction technology allows even sub-micron sized microbes to be trapped. It now has a reduced effective dead-space of 65mL.

The unique square shape allows efficient use of this nanotechnology and expensive filter medium, resulting in less waste and therefore, a lower price to the end user.

Testing has shown that the unique new 25mm mouthpiece is much more comfortable for adults and children than other brands of respiratory test filters using a 30mm diameter mouthpiece.

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
• Mini SafeTway and Long SafeTway also 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 adaptor may be required.

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

Long SafeTway mouthpieces that are 50% longer to enable their removal without saliva transfer to the user are also available
