AirSense 10 I only used it twice, but it didn't suit me, so I stopped using it and stored it for about a year. It has been stored in a closet at home. It was purchased overseas, so the display is in English, but the operation is the same as the Japanese version, so I don't think there will be any problems. The items for sale this time are "everything in the first image". I have confirmed that it works and there are no problems at all. The set includes the main unit, mask, bag, tube, tube cover, filter, tank, and instruction manual, so it's ready to use immediately. By the way, the main unit alone is a product that costs around 300,000 yen. In addition, I will include a spare set of mask, headgear, humidifier tube, air tube, short tube, chamber (humidifier), and filter that I had. These are all brand new and unused. These alone cost tens of thousands of yen. Regarding shipping, I cannot ship to Okinawa Prefecture and remote islands. Depending on the customer's shipping address, it will be either Japan Post, Sagawa Express, or Yamato Transport, but you cannot specify the carrier. Please understand. In addition, due to work reasons, it may take several days (up to 7 days) to ship, so please refrain from purchasing if you are in a hurry. I cannot advise on the feeling of use, as it varies from person to person. Also, since I have already confirmed the operation, there will be no follow-up after the handover to prevent any post-sale problems. Please consider this before purchasing. Also, please refrain from purchasing if you are a nervous person who is concerned about minor details. Although it has only been used a few times, please understand that it is a used item before purchasing.
