Water filter cartridges that exceed their recommended usage time without timely replacement can affect filtration function and efficiency. Moreover, it also impacts the lifespan of cartridges not yet due for replacement.
For instance, expired coarse filters lose their ability to remove impurities and debris, leading to dirty water sources, blockages, decreased filtration function, and reduced lifespan of RO membranes.
Failure to replace cartridges regularly results in them becoming clogged with dirt buildup.
Output water quality is not guaranteed.
As filters age, their ability to remove impurities, bacteria, and viruses diminishes, resulting in inadequately filtered water that can affect health.
Slow water flow rates may not be sufficient for use.
The incoming water source is visibly laden with impurities and sediment. Over time, these accumulate, forming thick deposits that reduce water flow through the membrane, causing slow flow rates, prolonged waiting times, and inadequate usage satisfaction.
Weak performance, with the machine dispensing water in small droplets, insufficient for use.
Results in higher expenses.
As previously mentioned, neglecting regular replacement of filter cartridges can impact function, filtration efficiency, decrease machine lifespan, leading to malfunctions, breakdowns, and incurring repair costs.
Therefore, all types of water filtration machines are recommended by manufacturers to adhere to specified replacement intervals to ensure abundant, pure water supply, prolong machine lifespan, and safeguard family health.
2. How often should water filter cartridges be replaced?
Each water filter cartridge serves a different function, so the replacement interval for each cartridge will vary:
Filter Cartridge 1
This cartridge comes into direct contact with the incoming water source, preventing visible dirt, mud, and rust. Therefore, it accumulates thick layers of dirt over time and has the shortest lifespan among the cartridges.
Cartridge 1 needs replacement after approximately 3-6 months, equivalent to using 18,000 liters of water. It has a lifespan of about 4 months with tap water and only 2-3 months with well water.
Coarse filters have low replacement costs but short lifespans.
Filter Cartridge 2
Considered the heart of water filtration systems, the RO membrane is crucial for ensuring purity by removing solids, heavy metal ions, bacteria, and toxins that could lead to diseases such as cancer and digestive issues.
The RO membrane has a longer lifespan compared to other filtration components, typically lasting between 24 to 36 months before replacement is necessary. Despite higher replacement costs, it outperforms sediment filters 1, 2, and 3.
Undoubtedly, the RO membrane plays the most pivotal role in the filtration setup of water purifiers.
Functional Filter Elements
When is it time to replace functional water filter elements? These filters are designed to eliminate chlorine odors, balance pH levels, and replenish essential minerals like potassium, magnesium, phosphorus, and calcium, resulting in naturally sweet-tasting water.
The replacement interval for functional water filter elements typically ranges from 12 to 24 months, depending on the quality of the input water, daily water consumption, and the type of membrane used.
In summary, the frequency of water filter cartridge replacement depends on its function, water source, and product model. Hopefully, the information provided in this article will assist you in using water filters effectively.
