Protect your patient and your testing instruments with the VBMax™ Pulmonary Function Filter. VBMax™ provides a high degree of protection for the patient as well as your testing equipment, while its low resistance allows for accurate testing results.
Independent laboratory tests have verified that this pulmonary function filter is highly effective. VBMax™ consistently filters out more than 99.999% of bacteria and 99.99% of viruses. At the same time, VBMax™ easily surpasses published ATS recommendations for flow resistance in pulmonary function instrumentation, which suggest resistance should be below 1.5 cm H2O/L/sec at flow rates of 14 L/sec.
