Clean water is a basic need that is very important for every household.
However, the quality of available water does not always meet the desired standards for consumption and daily use. Therefore, household water treatment systems are becoming an increasingly popular solution to ensure the availability of clean and safe water at home. One of the key components in a water treatment system is the filter cartridge. Choosing the right filter cartridge can make a big difference in the quality of water produced. In this article, we will take an in-depth look at household water treatment and tips on choosing a suitable filter cartridge for your system.
Household water treatment systems generally use water sources from PDAM (Regional Drinking Water Company) or wells, or sometimes a combination of both. Water from these sources then goes through a series of treatment processes to remove various contaminants and improve its quality. This process usually involves using a pump to run the water through a filter or water softener system to remove substances such as iron, silica, and other contaminants. In some cases, reverse osmosis (RO) systems are also used for more thorough water purification.
The choice of an appropriate water treatment method depends largely on the quality of the source water and the specific needs of the household. For example, homes using well water may face issues with iron, manganese, and possible bacterial contamination due to leaks from septic tanks. On the other hand, PDAM water that comes from rivers may contain contaminants from household and industrial waste. Some people also use drinking water refill services, which while convenient, can pose a microplastic problem.
To address these challenges, an often-recommended solution is a whole-house water treatment system installed at the point of water entry, either from a well or PDAM. If using PDAM water, this system usually simply uses a carbon filter or water softener, followed by a chlorination process. However, some people dislike the smell of chlorine, which is actually a sign that the water has been properly disinfected.
Understand the Types of Filter Cartridges
Cartridge filters are an important component in household water treatment systems. There are various types of filter cartridges available in the market, each with different functions and characteristics. Some commonly used types of filter cartridges include:
- Sediment Filter: Serves to remove coarse particles such as sand, mud, and rust.
- Sediment Filter.
- Carbon Filter: Effective in removing odors, tastes, and dissolved organic compounds.
- Carbon Filter.
- KDF Filter: Uses KDF (Kinetic Degradation Fluxion) media to remove chlorine, heavy metals, and bacteria.
- KDF Filter.
- Resin Filter: Used in water softening systems to remove hardness.
- Resin Filter.
- Membrane Filters: Includes ultrafiltration and nanofiltration filters that can remove very small particles and some microorganisms.
- Membrane Filters.
The choice of the right type of filter cartridge depends on the quality of the source water and the purpose of treatment. For example, if the source water contains a lot of sediment, then a sediment filter is the right choice as the initial stage of treatment. Meanwhile, a carbon filter is very useful for removing unwanted odors and tastes, especially in chlorinated water.
For homes with a higher budget, a whole-house reverse osmosis (RO) system may be an option. RO systems are capable of removing almost all contaminants, including dissolved salts, heavy metals, and microorganisms. However, these systems require a larger investment and higher energy consumption.

Questions and Answers
1. Is PDAM water always safe to drink directly without additional treatment?
Answer: Although PDAM water has gone through a treatment process, its quality can vary depending on the location and condition of the distribution pipes. In many cases, additional in-home treatment such as filtration or UV disinfection is recommended to ensure drinking water safety. This is especially important if you live in an area with aging water infrastructure or if there are concerns about contamination during distribution.
2. How often should I replace the filter cartridge on a household water treatment system?
Answer: The frequency of filter cartridge replacement depends on several factors, including filter type, source water quality, and level of use. In general, sediment filters may need to be replaced every 3-6 months, while carbon filters can last 6-12 months. However, if you notice a drop in water quality or a significant drop in water pressure, it may be time to replace the filter earlier. Always follow the manufacturer's recommendations and check your filter regularly.
3. Do reverse osmosis (RO) systems remove essential minerals from water?
Answer: Yes, RO systems do remove most minerals from water, including some beneficial minerals like calcium and magnesium. However, this is not always a problem as most of our mineral intake comes from food, not water. Some modern RO systems come with a remineralization stage that adds important minerals back into the treated water. If you are concerned about this, you could consider an RO system with a remineralization feature or consult a nutritionist about your mineral needs.
