Generally speaking, the service life of the filter element: PP cotton filter: 3-12 months; Pre-activated carbon filter: 3-12 months; Ultrafiltration membrane filter: 3-12 months; RO membrane: 12-36 months; Post-activated carbon filter: 12-24 months.


But this is only a vague conceptual criterion. For example, during the validity period of the filter element, the whole family went to travel for a period of time, and the filter element was not used during this time, so should this period of time also be counted in the service life? These are hard to judge.


Activated carbon filter manufacturers teach you several ways to determine when to replace the filter:


1. The effluent flow becomes very small (indicating that the filter element is blocked, and the filter element should be cleaned in order to restore the normal flow), and the flow rate is still very small after cleaning, which cannot meet the needs;


2. The taste of the effluent decreases, and the taste is close to the tap water, that is, the chlorine taste of the tap water cannot be removed, indicating that the activated carbon filter element has been adsorbed and saturated, and the activated carbon is invalid;


3. The filter element has not been replaced for one year.


The manufacturer of the activated carbon filter element said that the above situations occur, indicating that the filter element needs to be replaced, but it is a bit of a painstaking task.
