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.
This is a common question on what are carbon filters for water filtration, it is a filtration method that uses a bed of activated carbon to remove impurities. Activated carbon filters are most effective in removing chlorine, particles such as sediment, volatile organic compounds (VOCs), taste, and odor. It also helps in removing microbial contaminants such as calcium and magnesium, bacteria and viruses, fluoride, nitrate, and other compounds.
An Activated carbon water filter plays a very important role in the process of water purification as it helps to remove all the unwanted chemicals and organic compounds like pesticides, chlorine, and other Volatile Organic Compounds (VOCs) that might be present in the water.
An activated carbon filter is helpful in removing naturally occurring or disinfection tastes and odors from water. As it won't remove bacteria, in order to remove chemicals and bacteria, it is important to use a reverse osmosis or distiller system.
It is important to remember that you must never wash a charcoal filter with soap as it can negate the charcoal's ability to filter air or water. Rinsing the filter with hot or warm water can also affect in the same way as well as it will help to release any absorbed pollutants into the air. If the pores in the charcoal have been absorbed, then you must replace the filter.
Carbon or charcoal is known as a naturally absorbent material because of its porous nature even if it is not activated. When activated, it has the most absorbent materials which are used to filter both the air and water. In purifiers, it helps in removing all the unwanted chemicals and organic compounds like pesticides, chlorine, and other Volatile Organic Compounds (VOCs).
