This is a set sale of the Kurita Cleansui AS-10N water purifier body and cartridge. The cartridge has a short usage period of about 3-4 months, so I think it can still be used, but please understand and acknowledge that it is a used cartridge before purchasing. The cartridge is also sold as a set, but since the cartridge is a consumable item, I recommend replacing it with a new one if possible. When replacing with a new cartridge, flush with running water for about 5 minutes. Please use the used cartridge after flushing with running water for about 5 minutes, just like when it's new. Usually, it is sold as a complete set (including the cartridge), and the body (container) only is not sold. I think it's a great deal to buy this product and purchase only the cartridge new. Photo 3 You can easily install it by connecting it to "in" and "out" with a flexible tube, etc. The product condition is clean as you can see in the photos, but it is not new, so please purchase only if you understand. *This product is also listed elsewhere, so the first person to purchase will be given priority. Also, I may delete it without notice. If you wish to purchase, please comment. I will check the stock. Days until shipment: 4-7 days, but I would like to respond as quickly as possible. I do not ship on Saturdays, Sundays, and holidays because I am busy with work. I think it will be shipped on weekdays. Thank you very much.
