Carbon Filter

[shubham Inc]

Activated carbon filters remove/reduce many volatile organic chemicals
(VOC), pesticides and herbicides, as well as chlorine, benzene,
trihalomethane (THM) compounds, radon, solvents and hundreds of other
man-made chemicals found in tap water. Some activated carbon filters
are moderately effective at removing some, but not all, heavy metals.
In addition, densely compacted carbon block filters mechanically
remove particles down to 0.5 micron, including Giardia and
Cryptosporidium, turbidity and particulates. Although some iron,
manganese, and hydrogen sulfide will be removed by these higher
quality activated carbon filters, a manganese greensand iron reduction
filter is generally preferred to remove these contaminants as the
effectiveness of carbon filter against iron and manganese is generally
short-lived if the contaminant concentration is high.

Carbon filters are NOT generally successful at removing dissolved
inorganic contaminants or metals such as minerals/salts (hardness or
scale-causing contaminants), antimony, arsenic, asbestos, barium,
beryllium, cadmium, chromium, copper, fluoride, mercury, nickel,
nitrates/nitrites, selenium, sulfate, thallium, and certain radio
nuclides. Removing these contaminants requires either a reverse
osmosis water filter system or a distiller (some can also be removed
by KDF-55 or manganese greensand).

GAC does not remove sediment / particulate material very well, so they
are often preceded by a sediment filter. Sediment pre-filters also
prolong the activate carbon cartridge life by eliminating gross
contaminants that would otherwise clog the activated carbon thereby
reducing the surface area available for absorption. Carbon block
filters are generally better then GAC filters at removing sediment.
