Carbon Filter

Carbon filters can remove most of the organic compounds, which cause aesthetic problems (taste and odor). The longer the filter remains in contact with water, the more effective it will be in removing the foreign matter. Some of the typical examples of carbon filters include faucet mounted, in line, line bypass, point of entry, pour through, and specialty filters.

Faucet mounted filters are connected to the faucet directly. In line filters are placed under the sink on the supply line of cold water; it means that hot water is not filtered. Line bypass models are based on a separate faucet at the sink that supplies only filtered water. Water from the existing fixtures will stay on untreated. Point of entry (POE) systems feature a filter, which treats all water entering the home. These systems have also found to be useful in removing volatile organic compounds, which would otherwise disperse into the air. However, these systems are also the most expensive.

Pour through filters are the most common and are the least expensive. These filters are not attached to a water line in the house, but instead the water is poured through the filtering system. Pour through filters do not filter large quantities of water and may not be the most effective type of carbon filter. The final type of filter is the specialty filter that can be attached to water supply lines on the refrigerators and ice makers. With all of these, it is important to realize that the filter should be replaced should the odor or taste problem reappear. Carbon filters do not regenerate themselves.

Design
The basic design and structure of an active carbon filter is similar to that of the standard filter. These filters have an additional layer of active carbon, which absorbs harmful and foul-smelling gases like ozone, nitrogen, oxides, sulfur dioxide and hydrocarbons. Standard cabin filters can be easily replaced by active carbon filters of the same construction without any modifications to the vehicle.

These filters use carbon of a specific grades as media and are primarily used for polishing applications, i.e. For the color and odor removal. Internally it is equipped with inlet distributor and a bottom collecting mechanism. Externally, it is equipped with frontal pipe work and isolation valves. As the main application of carbon filter is to remove color and odor, a sand filter is generally required as pretreatment to this filter so as avoid the accumulation of suspended particles over the carbon.

Advantages/ Benefits
An important advantage of carbon filters is that they provide the driver even more comfort and health protection through the filtration of foul smelling harmful gases.
