Commonly referred to as “charcoal filters”, granular high activated carbon filters are made from naturally occurring raw materials (coconut shells or coal). The material is “activated” by introducing high heat which increases the surface area and, therefore, the filtering capacity of the media. Carbon filters are commonly used to treat foul odor, bad taste, or to remove chemical impurities from the water supply. These systems are ideal for municipal water applications where chlorine taste and odor can be a nuisance. Since the filtering capacity of carbon degrades over time it is important that the media be changed regularly to maintain filtering ability. If you are experiencing a bad taste or odor to your water or suspect chemical intrusion, this may be a solution. Call us and we can recommend the system that is best suited to your needs.
