The activated carbon filter is essential for removing chlorine, volatile organic compounds (VOCs), and bad tastes and odors from the water. Activated carbon has a vast surface area with many pores, allowing it to adsorb a wide range of chemicals.
Function:
- Eliminates chlorine and improves taste and odor.
- Reduces harmful chemicals, making water healthier.
Frequency of Replacement: Every 6 to 12 months.
2.3. Third Stage: Reverse Osmosis Membrane
The reverse osmosis (RO) membrane is the core of a 4-stage water filtration system. This semi-permeable membrane is capable of filtering out contaminants at a molecular level, allowing only clean water to pass through. It effectively removes contaminants such as lead, arsenic, fluoride, and other dissolved solids.
Function:
- Provides thorough purification by removing over 95% of dissolved solids and contaminants.
- Ensures water quality is safe for consumption.
Frequency of Replacement: Every 2 to 3 years.
2.4. Fourth Stage: Post Carbon Filter
The post carbon filter is the final stage of the filtration process. It is designed to remove any remaining tastes, odors, or impurities that may have escaped the previous stages. This filter often uses activated carbon again to polish the water before it reaches the tap.
Function:
- Ensures the best tasting and smelling water for the end user.
- Serves as a final quality check on the purity of the water.
Frequency of Replacement: Every 6 to 12 months.
3. Benefits of Using a 4-Stage Water Filtration System
