A high quality under sink water filter will have a multi-filtration system that improves your tap water and potentially your health by doing the following:
1. It will reduce sediment and turbidity, tiny microscopic particles that causes the water to look cloudy and smell bad
2. It will remove chlorine. You may have thought that this substance was all good. After all, it kills the bacteria in the water supply. However chlorine is linked to respiratory illnesses like asthma and bronchitis.
So when you drink water or have a shower, you are potentially exposing yourself to a health risk.
3. It removes the very harmful contaminant – lead with an advanced ion exchange process. Lead by the way can also enter your tap water from inside your home plumbing system. This ion exchange process also gives your tap water a nice spring water taste.
4. It removes synthetic chemicals – many of which are linked to cancer and kidney and liver problems
5. It removes chlorine resistant organisms. Many of those organisms can cause flu-like symptoms. Old people and infants are especially vulnerable to these organisms.
So as you can see, an under sink drinking water filter system can improve upon the taste and safety of your tap water.
However, some people will say our tap water is safe. They contend that city treatment removes the harmful contaminants. Indeed, city water treatment does that. However, trace amounts of contaminants still exist in the water supply.
As a matter of fact, some scientists contend that over a number of years, drinking water that contains trace amounts of contaminants that can affect our health.
The key is to get a quality under sink drinking water filter system. You need to be know what to look for so that you can identify such a device.
