Mostly from two natural resources: surface water, such as ponds, lakes, rivers, creeks and streams, and ground water that is extracted by means of a well. But regardless of the original source tap water unfortunately is not at all safe to drink.

It contains numerous impurities that can be harmful to your health.

Heavy metals, such as cooper, iron, lead, fluoride, radon can occur naturally. Some substances can contaminate ground water leaching through the soil or from the plumbing pipes. Among those very dangerous contaminants are fertilizers, asbestos, cyanides, pesticides and numerous industrial chemicals. To kill bacteria and to adjust PH some substances, such as chlorine, carbon, lime, soda ash, phosphates and aluminum sulfate are added intentionally.

But even with these actions taken the water still could be contaminated with viruses, bacteria and parasites.

One of the America's leading authorities on water contamination, Dr. David Ozonoff of the Boston University School of Public Health states, "The risk of disease associated with public drinking water has passed from the theoretical to real".

There is only one possible way of removing all undesirable substances right at the "point of entry". It is to use one of the best filters offered on the market - the whole house water filter.

Only whole house water filter can remove contaminants that potentially hazardous to your health along with hundreds chemicals that can cause "rotten-egg" smell of the water.

Whole house water filter can remove bad smell and taste of the water that comes from a lake or reservoir and is polluted by algae.

The biggest problem of the tap water we use in our household is huge amount of chlorine that is intentionally added in public water supplies to kill bacteria, adjust PH and eliminate cloudiness.

Chlorine is incredibly harmful for your skin and hair, because it kills cells and attacks the oil that retains moisture.

Washing clothes in chlorinated water fades color and is damaging to fabric.

But most hazardous is chlorinated gas that evaporates from hot water when you take a shower. This gas is one of the most common sources of indoor air pollution in many households.

Studies show that most American homes have higher level of chloroform gas caused by chlorine evaporation from treated water. Chlorine gas is released into the air every time you shower, bathe, flush the toilet or wash your clothes with chlorinated water.

This is very dangerous for kids, asthma suffers and people with weak immune system.

Only whole house water filter can give you chlorine free water in tap, bath and shower. Chlorine free showers will leave your skin softer, and more hydrated thus younger-looking and suppler. Your hair will be silky smooth and hair color will last longer.

Fresh and clean laundry free of chlorine will not ruin your clothes.

You will have better tasting water at every tap in your house. Using whole house water filter will guarantees that the air in your home will be much cleaner and healthier.

Using whole house water filter will prevent your major appliances from rust, caused by iron present in the unfiltered water. Iron can also stain fixtures, such as sinks, showers, toilets etc. In the iron rich water certain bacteria that thrive in hot water heaters produces hydrogen sulfide the source of "rotten-egg" smell.

So, it is imperative to clean and purify water, used in your household by the means of whole house water filter.
