Mitsubishi Chemical Cleansui Cartridge Super High Grade One unused item. I threw away the box and instruction manual, so they are not included. I used to use a Cleansui water purifier, but I replaced it with a different water purifier, so I am selling one extra cartridge. The bag is unopened. The product model number is not written on the cartridge, so I don't know it. Also, I don't know which water purifiers it is compatible with, so please research thoroughly and purchase only after you are satisfied. Returns and exchanges cannot be accepted.
