VF2180-2, VF-2181, and VF-2182 spirometry filters are disposable barrier type
filter intended to protect both patient and instrument by preventing the
transmission of pathogens by droplets and aerosolized particles between the
patient and the spirometer, or pulmonary function testing instrument.
Independent studies with bacterial and viral aerosols demonstrate 99+%
filtration.

FEATURES

• Prevention of cross contamination during lung function tests
• Features an elliptical end for patient comfort
• Low Resistance to airflow for accurate pulmonary function testing
• Minimal dead space to preserve accuracy of spirometry measurements
• Electrostatic properties that trap bacteria and viruses which prevent
  contamination to both patient and equipment
