How often should you change the NObreath mouthpiece?

Please be advised that the NObreath mouthpiece is single-patient-use only and can be used multiple times in one sitting, but if used across multiple sittings then the mouthpiece should be used for a maximum of 10 tests. Re-use of this mouthpiece can increase the risk of cross-infection and may result in decreased accuracy of results.

If the problem persists or has not been resolved by the information provided above, please contact Bedfont or your local distributor for more advice.
