eSpring 2 Replacement Filter Cartridge for Water Purifier Amway This is a water purifier filter removed in November 2024. It was installed new in October 2023, so it was in use for about 1 year. Since it was replaced after one year of use, the remaining Blue lamp is off. In reality, I was away from home on business, so it was hardly used and is clean. The replacement time for the eSpring 2 water purifier cartridge is 1 year or 5,000L (approximately 13.7L per day) of purified water usage. Most people end up replacing it before using up 5,000L (approximately 13.7L per day). This product is for those who: ○ Want to use it until they can afford to buy a new one ○ Want to have a filter installed for the time being ○ Don't mind used items ○ For demonstration purposes Please understand that this is a used item for demonstration or temporary use. A new one costs 22,550 yen. I will put the cartridge in the box and ship it.
