Questions & answers
Can I reuse the Spirette mouthpiece?
The Spirette mouthpieces are single-use only and disposable.
Can I wash/disinfect the Spirette mouthpiece?
To avoid cross contamination the Spirette mouthpiece is recommended to be used only once. Washing / disinfection of the Spirette mouthpiece might damage sensitive parts, which may compromise the test results and the safe avoidance of cross contamination.
Can I use any breathing tube on the market for testing, as long as it fits into the sensor?
As a crucial component of the TrueFlow technology, the measurement accuracy is also ensured by the ndd Spirettes/EasyOne FlowTubes, which are precision-manufactured and undergo stringent quality inspections. Therefore we highly recommend using the original ndd Spirette/EasyOne FlowTube to fully benefit from the TrueFlow technology.
