[Used] Mizu Kobo Standard Water Purifier Unit (Head for JA4-02) Manufacturer: Takagi Part Number: JH030JA4K-02 Used for approximately 3 years. I am selling the removed head (water purifier unit) because I received a new one as a regular replacement member benefit. It was working without any problems until it was removed. - Water purifier cartridge not included. - I cleaned it as much as possible, but there may be some water stains that couldn't be removed. Please check the photos and consider purchasing only if you understand that this is a used item. #JH030JA4K-02 #JA4-02
