Purchased around 2021. I often had asthma-like coughing fits 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, though not every day. After that, as my body grew, my visits to the doctor decreased, and I kept it in storage. As shown in the photos, there is some yellowing of the main unit and dirt on the power cord due to aging, but the 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. New: Mouthpiece 3 (out of 5 in a pack) Nosepiece 4 (out of 5 in a pack) Nebulizer kit 1 Cap 1 Baffle 2 (pack of 2) 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 there is no dirt or scratches, so it is considered to be almost unused. The unopened parts alone cost 2000 yen. No outer box. It's ready to use immediately after purchase, so how about it if you're looking for a used one? Please refrain from purchasing if you are concerned about minor details.
