Household Water Filtration
The right household water filtration system for your home depends on the contaminants present. If you make the wrong choice, you could have the illusion of protection, while the reality is quite different.
One of the most common contaminants is chlorine. It smells bad, tastes bad and is bad for your health. The amount present in some supplies exceeds what is safe for use in a swimming pool.
It irritates the eyes and respiratory system. When consumed, it causes digestive complaints and anemia in children.
The best step for removing chlorine is activated carbon. Systems are available that include activated carbon granules, a solid activated carbon block or both. Logically, the systems with both remove the greatest amounts of chlorine.
Whenever a source is chlorinated, chlorination byproducts called THMs are produced. Actually, any disinfection process produces hazardous byproducts that may be carcinogens. Chloroform gas, which is a THM, is a known carcinogen. It is produced when chlorine interacts with living cells such as bacteria or other chemical compounds.
If you currently use antibacterial soap to wash your hands or take a shower, you need a household water filtration system in multiple locations. A whole house filter might be the right choice. The filters must be installed by a plumber. They attach at the point where the waterlines enter your home.
The connection between antibacterial soap and chlorine is this. The usual ingredient in the soaps is triclosan. Triclosan reacts with chlorine to form chloroform gas.
Other contaminants may or may not be present in your supply. You can have testing done or treat for the most common ones. Lead, cysts, pesticides and other chemicals are among the most common. Chemical molecules are too small to be trapped by public treatment steps.
A reverse osmosis household water filtration system is unnecessary unless you have a contaminated well. Currently, reverse osmosis is the only step to reduce arsenic and other dangerous naturally occurring minerals. You would need to have your well tested to find out if the step is necessary for you.
If you do find that reverse osmosis is necessary, you will still need a carbon filter at your kitchen faucet. The porous membranes of the reverse osmosis systems allow chemical molecules to pass through. Carbon granules work by trapping the chemicals on their surface.
Finding a reasonably priced household water filtration system could be important to you. Remember to compare the cost of use, not just the cost to purchase. Replacement filters can be expensive.
