The OMRON COMP AIR nebulizer is the perfect device for respiratory treatment. - Brand: OMRON - Model: COMP AIR - Function: For nebulizer treatment - Power Source: AC power - Color: White Thank you for viewing. I purchased this a few years ago for my child, but we only used it a few times and their symptoms improved, so it has been stored at home. The inhalation mask and hose are in relatively clean condition. I disinfected it before storing it, but please disinfect it again before use. Other included accessories are unopened. Regarding the carrying bag, there are some white stains on the outside and inside (please check photos 7, 8, and 9). The original cardboard box it came in is not included. I will pack it with bubble wrap and ship it in a cardboard box, so please understand. This is a home-stored item and has been inspected by an amateur, so please purchase it if you understand this.
