Takara Standard This is a complete water purifier set. Given the current state of Japan's water supply, a water purifier is essential! Let's incorporate one for the sake of our health! This item was used until 2025/11/8. The filter replacement timing is unknown. The purchase date of this item is also unknown, but it looks new. If you are in eastern Aichi Prefecture to western Shizuoka Prefecture, I can install it for you, including drilling a hole in your kitchen, for an additional installation fee. Please consult in the comments.
