Spirometry Filters

Our spirometry filters are available for our spirometer SpiroConnect, but also for all other common spirometry and pulmonary function devices.

Since the outbreak of the COVID19 crisis, antibacterial/antiviral spirometry filters have become indispensable when performing spirometry. Bacterial filters are also highly recommended when using disposable sensors, as the disposable sensors do not prevent the spread of potentially infectious aerosols.

Our spirometry filters are designed to be as comfortable as possible, with a modified oval mouthpiece for a better containment of the lips and ridges for better clamping between the teeth. in addition, extra attention was paid to the lowest possible resistance to the air flow.
