Pure Water Filter

Updated on September 27, 2010

For many people who live in areas where their tap water may not be up to par in the purity department, there is the option to filter the water using one of the many water filtration systems that are currently available.Let's face it, do you really want to leave your family's health to chance?

Most water authorities tend to brush under the carpet any information that might be detrimental to their reputation for providing quality drinking water straight from the tap. But if you dig deeply enough, it will become apparent that even in places where you think your drinking water is completely safe, there are more toxins, heavy metals and bacteria floating around in that glass of clear water than you might imagine.

A good drinking water filter system should remove most if not all of the toxins and bacteria that get into drinking water. This hub page looks at how they work and why you should seriously consider filtering your residential water supply.

How Pure Water Filters Work

The majority of house water filters work by a process known as reverse osmosis, where the water is passed through several filtering stages using charcoal and other materials and finally through a membrane so fine that even bactreria cannot pass through. This leaves the filtered water free of toxins such as pesticide and herbicide residues, heavy metals such as lead, aluminium and iron, micro organisms such as tiny parasitic insect larvae and harmful bacteria.

However, some residential water filters produce water that is so pure that it actually tastes strange because we're not used to such a degree of purity. To rectify this problem, many of the better quality water filtration systems use an auxiliary filtering system which actually replaces some of the harmless elements present in clean water to replace the taste that we're accustomed to.

Whole house water filter systems are capable of filtering all of the water that enters the home from the water main and provides not only clean drinking water, but also soft water for washing. 

The physical pure water filter unit generally fits neatly under the kitchen sink, although larger whole house water filters can be situated in a convenient place out of the way.

Why You Should Consider a Pure Water Filter System  

Even the cleanest looking water that comes out of the tap contains a certain level of toxins, bacteria and other micro organisms, as well as heavy metals, chlorine and farm pesticide residues that have leeched through the soil over the years and reached and polluted the water table in most agriculturally active countries.

These elements are present in your drinking water and there are certain ways to test for them. One of the most horrific tests I personally ever witnessed was a simple electrolysis test of tap water taken from a local kitchen tap. Within about two minutes of sustained electrolysis, the water turned black and a black and dark green precipitation formed on the surface. This was simply the heavy metals and other toxins precipitating out due to passing an electrical current through the water. The metals become magnetized and clump together along with electrically charged ions form a collection of other elements present in the water.

The same test was then performed on water taken from the same source but first passed through the water filtration company's own water filter. the water remained clear after two minutes of electrolysis to display the filter's success at removing these toxins from the water.

I then witnessed the same test done on several new units of bottled so-called pure or mineral waters with unbroken seals as control subjects. Most of them failed the same test due to the heavy metals and toxins precipitating out to a lesser degree than the tap water but it was still evident that certain bottled waters were barely any more pure than the tap water itself. A few bottled waters did pass the test and remained clear after two minutes of electrolysis, proving that the test was not rigged in any way.

Other tests were carried out to display chlorine content, calcium content and other chemicals, although most tests were inconclusive. One interesting test to show the chlorine content of tap water involved an eye dropper test, where a chemical was dripped into a glass of tap water, which turned a light shade of green, revealing the presence of chlorine. The same test was performed where two glasses of the same tap water were placed side by side. In one, a quatered slice of raw tomato was placed for several seconds then removed. The eye dropper test was done on both glasses and the one that had contained the tomato slice did not change colour.

The very visible results of this test meant that cut fruit or vegetables actually soak up any chlorine that is present in tap water. Something you might want to think about nest time you're cooking with water from the tap...

Ultimately, the choice is yours whether you choose to filter your household water or not. If you do choose to fit one of the home water filtration systems, shop around for the best deals and watch out for any additional costs such as installation costs, which should be given up front upon purchase of a system.

A cheaper way of filtering your drinking water is to use a filter jug that you can buy relatively cheaply at most kitchen shops and stores. They employ a carbon filter system that can remove most of the toxins, heavy metals and chlorine from your drinking water. Some of the are designed to fit in the door shelf of a refrigerator, while otehrs can sit by your kitchen sink to be refilled as necessary.
