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.
