Blue BVF Bacterial Viral Filters – fits Vitalograph, round mouthpiece. Box of 50

Vitalograph Bacterial Viral FiltersTM (BVF) provide an efficient hygiene solution giving better than 99.999% cross-contamination efficiency, protecting the patient, operator and equipment from cross infection and contamination during pulmonary function testing.

Suitable for inspiratory and expiratory spirometry testing, these single-use bacterial viral filters provide effective protection from cross infection. Vitalograph BVFs feature an electrostatically charged barrier that filters droplets, aerosols, bacteria and viruses out of the airstream. 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. Improved hygiene can lead to lower running costs.

A wide range of BVFs are available to fit all leading makes of spirometers and PFT equipment. These may be purchased as standalone filters or in a kit with BVF, bite-on mouthpiece and noseclip options.
