Purchased around 2021. I often had asthma-like coughs during seasonal changes and had to use an inhaler at the hospital, so I bought a new inhaler at home for preventative use. I used it for about a year, although not every day. After that, as my body grew, my visits to the hospital decreased, and I kept it in storage. As shown in the photos, there is yellowing and minor scratches on the main unit due to aging, and dirt on the power plug, but the main unit's operation has been confirmed. Separate parts are also included. The filter was not attached to the main unit during inspection, so I opened a new one and attached it to the main unit. New: Mouthpiece 3 (out of 5) Nosepiece 4 (out of 5) Nebulizer kit 1 Cap 1 Baffle 2 (2 included) Air filter 4 (1 out of 5 is used on the main unit) ✴︎The air hose is not unopened, and there is some discoloration on the hose, but it is clean and has no scratches, so it is considered to be almost unused. The unopened parts alone cost 2000 yen. No outer box. The parts list in the photo is not included. It is ready to use immediately after purchase, so how about it if you are looking for a used one? Please refrain from purchasing if you are concerned about minor details.
