Mizu Kobo Standard Water Purifier Part (Head for JA3-03) Manufacturer: Takagi Used for approximately 1 year, and I am selling it because I replaced it with a new one. There were no problems with its operation until it was replaced. It has been sterilized and cleaned, but there may be some water stains that could not be removed, and some minor scratches. Please refrain from purchasing if you are sensitive to used items. This is a listing for the head part only; the water purification cartridge is not included.
