VBMax™ S-Series spirometry filters were designed for pediatric use as well as for situations where patients feel more comfortable with a smaller mouthpiece during spirometry maneuvers.

We designed the oval-shaped mouthpiece of the VBMax S-Series PFT filters to be approximately 35% smaller than that of VBMax Standard PFT filters. With some updates to the overall design, we achieved our goals without sacrificing the low resistance to flow that has helped VBMax family of pulmonary function test filters become popular worldwide.

A smaller mouthpiece may also be helpful to patients with temporomandibular joint dysfunction (TMD) or anyone with a limited maximum oral aperture. The S-Series VBMax also features three, equally spaced, superior and inferior ridges for a tighter and easier grip.
