Vitalograph Bacterial Viral Filters (Blue)

Unlike barrier filters, which trap expectorated matter whilst allowing viruses and bacteria to pass through, Vitalograph Blue Bacterial Viral Filters use an electrostatically charged material that traps expectorated matter plus bacteria and viruses. This combination is highly effective for 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 decontaminating test equipment. Technical Specifications: Efficiency: 99.99% at 55 and 750L/min Validation using Bacillus Subtillis var niger mean dia: 0.7 to 1 µm Resistance to Airflow at 750L/min (BVF alone): 0.08kPa/L/s (0.8cmH20) Resistance to Airflow at 750L/min (BVF + Fleisch): 0.12kPa/L/s (1.2 cmH20) Effective Deadspace (excluding Tapers): 65ml Material: Electrostatic nanofibre technology filter medium This particular blue filter fits Vitalograph, MIR, Creative Biomedics, and CareFusion MicroMedical spirometers.
