Disposable Bacterial/Viral Filters (Pack of 50)

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.

Compatible with:

• SpiroConnect spirometer
• SpiroUSB, MicroLab, MicroLoop and PulmoLife spirometers
• Vitalograph spirometers, respiratory monitors and screeners
• MIR spirometers

The importance of disposable bacterial filters in spirometry

The recent pandemic has highlighted that improved infection control and the use of bacterial filters is more important than ever. Each patient is susceptible to the risk of infection after performing a spirometry test because there is often very little screening of a patient’s infectious status before the test. However, these disposable bacterial–viral filters protect patients and equipment from viruses and bacteria, limiting the risk significantly.
