What is carbon
Carbon adsorption is the most widely sold method for home water treatment because of its ability to improve water by removing disagreeable tastes and odors, including chlorine. Because of these attributes, carbon filters are very well-suited for homes that use municipally treated water. Only a few carbon filter systems have been certified for the removal of lead, asbestos, volatile organic chemicals (VOCs), cysts, and coliform.

What will carbon remove

Activated carbon filtration may be selected to reduce unwanted tastes, odors, and organic chemicals (such as disinfection by-products, pesticides, and solvents) from drinking water. Activated carbon will also reduce radon gas and residual chlorine. Activated carbon filters will not remove or reduce major inorganic ions (such as sodium, calcium, chloride, nitrate, and fluoride). However, some can reduce lead, copper, and mercury. Activated carbon filters will not soften the water or disinfect it. If the water source is cloudy, this type of filter may be used after a particle filter to remove particles that may plug or reduce its efficiency.

What will carbon not remove

Similar to other types of water treatment, AC filtration is effective for some contaminants and not effective for others. AC filtration does not remove microbes, sodium, nitrates, fluoride, and hardness. Lead and other heavy metals are removed only by a very specific type of AC filter. Unless the manufacturer states that its product will remove heavy metals, the consumer should assume that the AC filter is not effective in removing them. Refer to the other circulars in the Treatment Systems for Household Water Supplies series for information on systems that do remove the contaminants listed above.

How long will my carbon last.

Since water quality varies from place to place, and may even vary in composition over time due to natural variances in makeup and how it might be treated, there is really no specific answer for time at which a carbon filter should be changed. The most common methods for determining when a filter should be changed include development of a noticeable drop in water pressure or a measurable drop in chlorine removal. Some filters have a filter change out alarm or indicator visible for consumers to see when to change their filter. Others have a stated life that is measured in gallons of water that can be filtered or months of typical usage while still achieving the desired chlorine reduction, but that life may be variable depending on the water.

The life of a carbon filter depends on the type of filter you have and what you are filtering. Any filter designed to remove particulates may prematurely block up if large amounts of sediment are present in your water. A carbon filter is mainly used for chlorine, taste and odour reduction. So if the carbon filter is saturated with taste/odour and other organic chemicals, it may lose its ability to remove any more chemicals from water. However, this depends on the level and type of chemicals in your water
