This is a replacement filter for the Amway eSpring Bathroom Water Purifier. It is a filter for a bathroom water purifier. The box is unopened. This is a replacement filter for the old type, so please be careful not to make a mistake. It is not a filter for the "Bath Spring Water Purifier." *I am selling two, so if you purchase them together, I will sell them for 33,500 yen (a 500 yen discount).* Thank you.
