Is there a signal to replace the cartridge



Yes,of course.Pls kindly see below:
1.Water production is too slow: whether the pre-filter element or reverse osmosis membrane is blocked;
2.Making water too fast (less than an hour to make a bucket): reverse osmosis membrane damage;
3.Poor taste: the post-activated carbon filter needs to be replaced; RO membrane removal rate is less than 75%: reverse osmosis membrane needs to be replaced.
