Hi Celia The training I did 3 or 4 yrs ago only advocated the use of filtered mouthpieces and I have never used anything else along with a washing of the turbine head (with hot soap and water) after each session. I find it also helps if a persons technique isn't good and they breath in via the tube before testing...the filters dont register on the spirometer unless I programme it to do so.

I regularly do health screening and as part of this obviously I do spirometry. I do and have always used flitered mouthpieces for obvious reasons. I am well aware of the risk of infection from using the non filtered tube type mouthpieces however the company I am currently doing some work for feel that the cost of filtered are too high and advised me that they can get them for much reduced cost. So can ,I but they would not be filtered and I refuse to use them on my machine. Can I have your comments on this please.
