While most families who buy water purifiers are aware of the need to periodically replace the filter to ensure that the water source is always clean and pure, ensuring the health of the whole family, some families often forget to replace the filter. Some families even forget to replace the filter for 2 years, leading to dirt being stuck and causing a blockage that prevents water from flowing out, so they call the service center.
The following article will help you better understand the function and time to replace the water filter so that the water source always meets the standards of pure bottled drinking water QCVN 6-1:2010/BYT.
Why do we need to replace Karofi water purifier core periodically?
The Smax technology filter core system is researched by leading experts from Karofi. Therefore, to better understand the filter, everyone should update their knowledge in the following section.
Operating mechanism of Karofi water filtration system
Smax is Karofi's exclusive technology that designs an optimal filter core structure, helping to maximize the water flow through, doubling the filtration capacity and doubling the service life. At the same time, the technology helps save up to 71% of wastewater.
Depending on the water quality, the company's rough filter cores can be used for up to 12 months, the functional core for up to 12 months, and the Ro membrane for up to 36 months. In particular, the Smax Ro membrane, which is from the US, operates based on the movement mechanism of water molecules.
With the support of a high-pressure pump, a huge force is created to help the input water source after passing through 3 rough filter cores 1,2,3, be pushed through the membrane layer with super small holes, only about 0.01 micrometers.
Then the water will go into the centering shaft (this is a water pipe with many holes to collect water) to bring pure water into the tank, the substandard water will go out through the wastewater.
When the user uses it, the standard water will go through 6 functional filter cores in turn and go out the faucet.
Harmful effects of overdue replacement of Karofi water filter cores
The filter system is the most important part of a water purifier. If you do not regularly check and maintain it, it will cause many dangerous effects.
Water quality is affected
The main function of the filter cores is to completely remove impurities, dirt, sand, and harmful bacteria from the water source. Not only that, the functional filter cores provide minerals necessary for a healthy body.
If you do not replace the filter cores regularly, the components will be clogged with dirt over time. Therefore, the water filtration efficiency of the purifier is reduced. Not only that, the quality of the water source is not guaranteed when dirt will re-enter. Therefore, you must pay attention to when to replace the Karofi water filter core so that the machine can replace the core periodically to ensure that the water source is not affected.
Reduce the life of the water purifier
In addition, when the filter is dirty and blocks the water flow, the filter will have to operate continuously at full capacity to provide enough 10-20 L/H. Therefore, the pressure pump is easily damaged, even explodes if it has to operate regularly.
Not only that, when the machine is filtering water, it will cause noise that affects people's activities and lives.
When to replace Karofi water filter core?
The machine's water filtration system consists of 3 main filter components:
- Raw filter group: Smax Duo filter technology
- RO membrane: Smax RO filter technology
- Functional filter group: Smax Nano filter technology
Each component has a different operating capacity and a different time to replace Karofi water filter core. The specific summary table below will answer the question of when to replace your Karofi water filter core. At the same time, everyone will better understand the structure and function of each type.
Therefore, you need to regularly maintain the filter and pay attention to the time to replace the Karofi water filter.

Introducing Smax RO filtration technology
| No. | Filter core | RO core function | Replacement time |
|---|---|---|---|
| 1 | Smax RO Purifim Core | Smax (Super Area) is a technology that designs the optimal membrane structure within the same membrane size. The membrane area in contact with water is arranged to be the largest, helping to maximize water flow. Thereby improving filtration capacity and prolonging the life of the membrane. | 24–36 months |
Introducing Smax Nano filter technology

Currently, the set of 6 functional filter cores is integrated into the high-performance core cluster HP 6.1 and HP 6.2. Instead of 12 joints as usual, the high-performance Smax core system is designed with only 2 joints, saving up to 44% space, minimizing leakage and re-infection, saving time and effort in replacement and installation.
Thanks to the optimal design, the output water flow is increased 1.5 times compared to normal, ensuring a regular and continuous supply of clean water.
