What types of point-of-use activated carbon filters are available?
There is a range of sizes of point-of-use activated carbon filters; faucet mounted under-the-sink filters, and wholehouse filters. The most common, but smallest, is the faucet-attached point-of-use filter. Quick and easy to install, this filter is either attached directly to the faucet outlet or placed on the counter and attached to the outlet via a hose. Some faucet attached filters have a lever that routes water into the filter only on demand, thus prolonging the life of the filter. A stationary activated carbon system can be installed under the sink. Before you buy this kind of system, measure the space under your sink to ensure a proper fit. Under-sink filters come in two types – those that filter all the water going through your faucet and those attached to the cold water line and a separate spout, thus using the filter only when desired. Whole-house units filter all water entering the house. This can be important when treating for contaminants which can be absorbed during bathing
