Absolutely not. A viral-bacterial filter creates a variable resistance that changes greatly depending on the moisture content in the filter. If the filter becomes saturated, it could be dangerous by obstructing flow and could lead to marked CO2 rebreathing. Plus, this variable amount of resistance could confuse the auto titrating algorithm. In addition, viral-bacterial filters create a transient laminar flow and a linear (not parabolic) pressure-flow curve. This would reduce both comfort and EPAP (therapy) compared to V̇-Com. V̇-Com has a specifically determined and constant resistance that clinicians may use to regulate the flow of the PAP circuit for the comfort and safety of their patients, and this resistance is not affected by conditions in and operation of the PAP device. Finally, a viral-bacterial filter, being uncleanable, would need to be changed often, resulting in exorbitant cost. V̇-Com is cleanable and reusable.
