Carbon Water Filter: What It Is & How It Works

Clean, safe drinking water is a basic need for man's survival. However, with the increasing concerns about water pollution and contaminants in the water supply, many people are considering a different range of water filtration systems to ensure their water is free from harmful substances. One popular category of water filters is the carbon water filter. This article explains what a carbon water filter is, its advantages, and how it works.

What Is a Carbon Water Filter?

A carbon water filter is a type of water filtration system that purifies water using activated carbon, commonly called active charcoal. Activated carbon is a type of carbon that has been processed to form a porous structure with a sizable surface area. Water contaminants are successfully removed from it as it goes through the filter, thanks to the porous structure of activated carbon, which retains them on its surface.

Advantages of Carbon Water Filters

Carbon water filters provide several advantages over other types of water filtration systems. Here are some key benefits of using a carbon water filter:

It Removes Contaminants Effectively

Carbon water filters effectively remove many impurities from water, including chlorine, sediment, VOCs, pesticides, and other chemicals. They can also improve the taste and odor of water by reducing unpleasant flavors and smells.

It Is Cost-effective

Carbon water filters are generally more affordable than other water filtration systems, such as reverse osmosis or UV filters. They are also relatively low-maintenance, as they typically only require periodic carbon filter replacement.

It Is Eco-Friendly

Carbon water filters are environmentally friendly, as they do not require electricity or produce wastewater, unlike other water filtration methods. Activated carbon is also a renewable resource, as it can be derived from various sources, such as coconut shells, wood, or coal.

It Is Easy to Install

Carbon water filters are easy to install and can be used as standalone units or as part of a more extensive water filtration system. Depending on the specific model, they can be installed under the sink, on the countertop, or attached to a faucet. For example, the Omnipure K5633SS inline GAC carbon filter is a self-contained design requiring no filter housing.

It Is Versatile

Carbon water filters can be used for various water sources, including taps, well, and rainwater. They can be used in residential, commercial, and industrial settings, making them versatile options for different applications.

How Does a Carbon Water Filter Work?

The basic principle behind a carbon water filter is adsorption, which is the process by which contaminants in water adhere to the surface of the activated carbon. The activated carbon in the filter attracts and traps a wide range of impurities, including chlorine, sediment, volatile organic compounds (VOCs), pesticides, and other chemicals that may be present in tap water or well water.

When water flows through a carbon water filter, the impurities in the water are adsorbed onto the surface of the activated carbon. As the water passes through the filter, the activated carbon acts like a magnet, attracting and trapping contaminants. This process effectively removes impurities from the water, resulting in cleaner and clearer drinking water.
