eSpring 2 Replacement Filter Cartridge for Water Purifier Amway This is a water purifier filter removed in May 2025. It was installed new in May 2024, so it was in use for about 1 year. Since it was replaced after one year of installation, 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 water purifier 2 cartridge is 1 year or 5,000L (approximately 13.7L per day) of purified water usage. Most people end up replacing it before using 5,000L (approximately 13.7L per day).
