Various Kinds of Water Filters

By John Adams


There are various types of water filtration systems available in the market for the homeowners to choose from. These units can be installed easily by following the manufacturer's installation instructions. Units should be chosen based on the contaminants that are required to be filtered. The countertop and faucet-mounted filters are easiest to install. However one should take into account that they are more bulky and not as convenient as the hidden undersink filter. Also if you are looking to filter and remove contaminants other than tastes, smells and lead these filters will not be of much help.

Whole-House Filters: Whole-House Water Filters are available and very simple to install. They're placed in the main water line entering your home and are designed to get rid of sediment and rust particles from all of the water entering your home. They can also benefit the other types of water filters by acting as a particulate prefilter.

Undersink Filters: There are several types of undersink filters available. You can choose them based on your home's needs. The filters are used to remove bad tastes and odors. There are some others that may remove lead, bacteria and sediment or any combination of these four. In such cases, these units would be having multiple cartridges, each of them designed to filter a specific contaminant.

Undersink filters are convenient because, once the are put in place, they cannot be seen. Turn on the water, and filtered water comes straight from the faucet. They're also efficient because they allow you to filter only the water going to a specific faucet, thereby reducing the demands on the filter cartridges. You don't need to filter your bath water to remove a chlorine taste, for example, but you may want to remove it from your drinking water. Undersink filters are also helpful if your plumbing is joined with lead solder. By being in line immediately before the faucet, undersink filters provide maximum filtration protection.

Faucet-Mounted Filters: These are small and easy to install/remove filters that do not require any plumbing connections and are connected directly to the faucet. Primitive models are designed to remove bad odors whereas advanced units have lead- and cyst-filtering capabilities. When using such filters water is filtered at the point of use. The disadvantages are that they are a highly visible attachment to the faucet and provide limited filtration compared to expensive undersink filters.

Countertop or Canisters Filters: These are the most simple water filters offered. They're countertop appliances, like toasters, and can filter drinking water for different contaminants. Unlike undersink filters, their use isn't transparent. Some of these filters must remain on your counter, some require connection to your spigot and some require that water be poured through them, similar to a drip coffee maker.
