Omron Compressor Nebulizer OMRON NE_C28 Purchased as a used item approximately 4 years ago. Used about 2-3 times a year for about a year. Omron Home Inhaler With instruction manual (Comes with a dedicated bag) Operation confirmed Stored in a bag in a dark place. The inhalation mask is included, but it is slightly yellowed. (See photos) Can be used with the mouthpiece. I will include the inhalation mask and mouthpiece, but if you are concerned, please purchase a new one separately. - Mouthpiece ⇒ Disinfected after use - Inhalation mask ⇒ Not used, but disinfected Please purchase only if you understand that this is a used item, inspected by an amateur, and stored at home. It was very helpful to be able to treat myself at home, so I hope someone who is having trouble can use it. #Omron #OMRON #HomeInhaler #NE-C28 #CompressorNebulizer
