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.
