Thank you everyone, I've checked into cost of whole house humidifier and was pleased to find they aren't that much at all, will be a good investment. Thanks for the hint on the InHealth adhesives, he is to use ATOS HME but hated their adhesives so I will try InHealth--we have samples of both. Not sure why he has been told he has to have the larygectomy tube, his air path and swallowing path are completely separate with the reconstruction done. I need to check if that's why he has to have the tube. His case seems to be so unusual it's hard to find information and even has his home town docs scratching their heads, it's becoming quite frustrating to determine how to help him continue to progress and he seems to be fine just settling.
