This is an Omron nebulizer, an inhaler. Purchased in 2016, it was used for my child's asthma treatment. It has been used for about a year. All parts are present. The parts have been soaked and sterilized, and the main unit and case, which cannot be washed, have been disinfected with alcohol. * Mouthpiece has scratches. * The small inhalation mask is slightly warped due to being stored bent. * As shown in image 10, the air filter has been removed. Please replace it with the new one attached when you use it. There are no major noticeable stains or damage, and the operation has been confirmed, but there are minor scratches and scuffs. Please consider this item with the understanding that it is a used item. Please read the profile. This item is available for immediate purchase.
