What is a carbon filter?

A water purifier comes with different set of filters with each playing a crucial role in purification process. Carbon filter is one of them which not just removes impurities but also act as a taste enhancer!

Carbon filters play a crucial role in the process of water purification as they remove all the unwanted chemicals and organic compounds like chlorine, pesticides, and other Volatile Organic Compounds (VOCs) that may be present in the water.

They are also effective in removing the smell and odor from water, while improving the taste of water. As water passes through a carbon filter, the activated carbon particles absorb all these impurities along with the bad taste and organic compounds.

Carbon filters are used both in the pre-RO and post-RO purification stages. Let’s understand the importance and benefits of each.

Pre-RO Carbon Filter

Pre-RO Carbon filter weeds out the impurities as much as possible before water passes to the RO membrane. This is mainly because the carbon filters have an advantage of a higher surface area where all the dissolved substances get attracted to the carbon particles on the surface. At this stage, the carbon filter is referred to as a Pre-RO Carbon filter.

Pre-RO Carbon filter also improves the life of the RO membrane by protecting it from chlorine which is known to damage the membrane by opening its pores. A long life of RO filter means a low maintenance cost for consumers.

As water passes through the carbon filter, it still contains some impurities like TDS, heavy metals that need to be purified. For this purpose, more stages of purification like RO and UV are added to ensure filtered water is entirely purified and is safe for consumption.

Post-RO Carbon Filter

After water gets filtered through RO and UV purification stages, another layer of carbon filter is added, called as Post-RO Carbon filter. Post-RO Carbon filter usually forms the last stages of water purification. This carbon filter purification stage helps in enhancing the quality of the water. It acts as a polisher, further improving the taste of purified water.

An RO water purifier which comes along with carbon filters is highly recommended for purification of water. Thus, it is important to invest in the right water purification device that could provide safe and healthy drinking water for you and the members of your family.
