There are lots of people worried about our water. And in particular about whether it’s healthy to drink it. If this worried you then you may be interested to find out some more about water filters and water filtration in general.

How do water filters work? Here are some of the things that you should know about the water purification process if you have thought about getting a filter for your home.

The first thing that you need to think about is why you need a water filter. There’s a huge range of different nasties that you can find in our drinking water and different filters filter different things.

There are many many different contaminants. Some can make your water taste bad, like chlorine, and can even cause your skin to dry out from showering. And there are many nasty chemicals found in water in small quantities that are known to cause cancer.

Its important to know that there are two different methods of water filtration. Physical filtration is the first method. It works by straining the water, using a tiny piece of textile membrane or gauze.

Having a water filter is about caring about your familys health and well-being. Having a water filter is to understand and know that the water you may be consuming daily isn’t as pure like many people assume. The problem of contaminated water does not just exist in third world countries rather it exists right here in our very own back yard. Sure! Water contamination is more prominent in third world countries than in the United States of America however we are still being affected by the same problem only to a lesser degree. While this may not be a problem for you, 45% of other fellow Americans complain about the water they receive from taps. Odor and a bad taste is the usual complaints however a new complaint is been warranted. This new complaint is that water which is being consumed is making people sick with diarrhea, head aches and sore stomach. The complaint has been diagnosed as water poisoning and in my opinion it is the new endemic problem that will only get worse. Already some chemical water poisoning cases have been linked to cancer, a new discovery that has a lot of people worried about their familys general health and well-being.

With reportedly more than 2,000 toxic chemicals in the water that we drink, if you want clean water at home, you must find the right reverse osmosis system to help produce ’safe’ purified water.

Reverse osmosis is a process that makes use of high pressure to force unpurified water through a semi-permeable membrane so that toxic chemicals are removed from the water. The only problem with this system of ‘cleaning’ water is that while toxins are removed, almost all other minerals (even trace minerals) are often also purged from the water, leaving water without any nutritional content.

Because there are so many types of water purification systems available, it is important to equip yourself with basic knowledge of their various designs and functions. For example there are two different types of membranes that a reverse osmosis filter system can be designed with. One is the CTA membrane or cellulose triacetate membrane, which is all natural and inexpensive. However, systems that use these membranes may require extra maintenance to prevent the cultivation of bacteria and this may result in a lower quality of purified water produced.
