Description
Unlike barrier filters which trap expectorated matter whilst allowing viruses and bacteria to pass through, Vitalograph filters use an electrostatically charged material that traps expectorated matter plus bacteria and viruses for highly effective protection against cross contamination. In addition to the hygiene benefits of using bacterial viral filters they also support productivity in pulmonary function testing by reducing the time spent cleaning and sterilising test equipment.
Vitalograph Bacterial Viral Filters (BVF) are independently tested for prevention of cross-infection. The results show that these are an efficient hygiene solution providing greater than 99.999% protection from bacterial and viral cross infection.
It is important to use Bacterial Viral Filters (BVF) in order to reduce the contamination risk to spirometers, pulmonary function testing equipment and respiratory monitors, and the potential infection risk to others. When a new BVF is used for every patient, the interior of the device is protected meaning that only exterior surfaces require cleaning.
