Vitalograph Bacterial Viral Filters Box of 50

Vitalograph BVF™ Bacterial Viral Filters feature an electrostatically charged barrier that filters droplets, aerosols, bacteria and viruses out of the airstream giving better than 99.999% cross contamination efficiency.

A BVF protects the patient, operator and equipment from cross infection and contamination during pulmonary function testing.

Improved hygiene with lower running costs; when a new BVF is used for every patient the interior of the device is protected meaning that only exterior surface cleaning should be required.
