What is a carbon filter? And what role does it play in water purification?
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.
Activated carbon used in Pureit carbon blocks are made of high-quality coconut shell which are manufactured by unique patented technology to provide maximum active surface area for absorption of these impurities. Pureit carbon block removes chlorine and other contaminants efficiently, till the last drop 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.
FAQs
1) What does a carbon water filter do?
Carbon water filters use activated carbon to filter tap water. It eliminates VOC (volatile organic compounds), chemicals, organic compounds like chlorine, particulate matter, taste, and odor from the water.
2) How often should carbon filters be changed?
The shelf life of carbon water filters is two to six months in the beginning. Later, carbon filters should be replaced every six months.
3) Are carbon water filters safe?
Carbon filters remove chlorine and other impurities from the water making it ideal for consumption. However, you have to replace carbon filters on a timely basis to consume safe water.
4) Do carbon filters remove hard water?
Hard water contains hard metals and minerals such as fluoride, arsenic, calcium, and magnesium. Carbon water filters can’t remove these contaminants from the water. Hence, they can’t reduce the hardness of the water.
5) What is the function of pre-carbon water filters and post-carbon water filters?
Pre-carbon filters in Pureit water purifiers remove sediments, volatile organic compounds, and chlorine from the water. A Post-carbon water filter eliminates the bad odor and bad taste in the water.
