⭐️ Waterproofing done! Waterproofing is applied after processing, so you can use it with confidence. Amway eSpring II eSpring Water Purifier Electronic Parts This is a special product, so please read the description carefully before purchasing. ※ This model frequently experiences cartridge display errors and emits warning sounds. Repairing it at Amway Japan costs over 10,000 yen. ※ It can be used without the warning sound, so you can replace the cartridge at your own timing. The replacement time for the eSpring II water purifier cartridge is 1 year or 5,000L (approximately 13.7L per day) of purified water usage. Most people end up replacing the cartridge before using up 5,000L (approximately 13.7L per day). The old model had a reset switch, but after the model change, it was designed to force a replacement. In environments with low usage, the cartridge replacement lamp and warning sound will activate before the cartridge is fully used. It's a waste to replace the cartridge before using 5,000L, so this is an electronic part that only silences the warning sound ♫ ⭐️ According to evidence, the purification function is maintained at the catalog-specified values for 1,000 liters after the replacement lamp comes on. # Must-see before filter replacement!
