Air humidifier with UVC disinfection

Question
Which experience is available for the use of air humidifiers with UVC disinfection in homes of CF patients? Can such humidifiers be recommended?
Answer
Hello,

I do not recommend the use of such humidifiers, since it is scientifically not proven that UVC light actually prevents bacterial growth in the humidifiers. Although you may find the declaration that "for disinfection of water UVC disinfection is the most efficient method", our own unpublished results demonstrate that this method does not lead to complete disinfection in contamination of humidifers with Pseudomonas aeruginosa.
