Disposable Bacterial/Viral Filters for the prevention of cross-contamination during lung function tests. Featuring an eliptical end for patient comfort, they are designed to allow the patient to use the filter itself as a mouthpiece rather than having to add a traditional mouthpiece.

Bacterial filters are the most practical and cost-effective way of ensuring that there is no risk of cross-infection between patients during spirometry testing. They have a maximum efficiency in trapping and removing up to 99.99% of bacteria and viruses.

Tests performed by Nelson Laboratories in the USA found our viral filters to be over 99.99% efficient in capturing bacterial and viral contaminants. Tests performed by the Health Protection Agency in England found the filters to capture over 99.4% of aerosol borne micro-organism spores of two different types tested. 

Find out why we now recommend Bacterial/Viral Filters in all spirometry testing.
