Omron Compressor Nebulizer NE-C803 Purchased in 2024, used for about six months. I no longer need it because I bought a battery-operated type. (I am also selling a nebulizer purchased in 2023) The mouthpiece has some wear and tear (cleaned and sterilized by boiling). If you are concerned, you may want to purchase a new mouthpiece. The inhalation mask was only used once, so the string is unused and clean. The kids' accessories, the rabbit one was opened, and the elephant one is unopened. There are 3 replacement air filters remaining. How about this as a sub-nebulizer, such as for use at your parents' house?
