This neb looks like a great idea, but the pamphlet I found online says it is meant for only 7 days of continuous use then dispose of it. Sorry I can't figure out how to attach the website. I just googled it. Maybe your doctor could order you enough and justify it with your insurance to use them for just the seven days. I usually only use a neb once then sterilize in the baby bottle sterilizer so I would hesitate to use for 7 days.
