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.
