This is a compact and portable nebulizer. I purchased it two years ago and used it for a few months. The mouthpiece has not been used. There is also a separately sold pediatric mask. The rubber on the mask has stretched out, so it is not included. I was advised by the hospital to use Milton for cleaning, and I have been using it. I still have some left, so I will include it. OptiChamber Diamond (mouthpiece type) inhalation aid, used for a few months.
