Electrostatic Spirometry Filter with integral mouthpiece
GVS Spiroguard utilise an electrostatically charged synthetic media. The positive and negative charge on filter fibres is generated during the manufacturing process and enhances the filter’s ability to attract particulate matter. Unlike other spirometry filters, GVS’s electrostatic filter media is covered in a protective scrim layer. This prevents fibres becoming loose, blocking the spirometer and therefore enhancing protective performance against harmful contamination.
The filter media has hydrophobic properties to minimise droplet contamination, as well as providing a low resistance and low dead space to improve the validity and consistency of respiratory testing results and minimise rebreathing.
