Activated Carbon Filter
The activated carbon or charcoal filter is another popular type of filter. The filter is layered with carbon, which absorbs contaminants, allowing the clean water to flow out. However, it is not capable of removing bacteria, which means it is not suitable in areas where the water contains a lot of bacteria or chemicals.
These filters also improve the taste of water, so the filtered water can easily be used for drinking and cooking.
As this filter is unable to remove bacteria, it cannot be used alone. You need to install another filter along with it to ensure that you are getting clean water.
- This is a natural filter and no chemical is used in the filtration process.
- Perfect for improving the taste and smell of water.
- Budget-friendly and low maintenance.
- If it goes unused for long periods, the filters can become filled with bacteria and will need to be replaced.
- Over time, the trapped contaminants pile up and affect the performance of the filters. Hence, frequent replacement is necessary.
