An in home water purification system filters water to make it safe for us to drink. Water purifiers were not necessary before, but they are indispensable now. A water purifier might be small, but it has a large and very important role to play.

Water purifiers are necessary, since treatment facilities have to add a lot of chlorine to kill all of the bacteria that ends up in our water supply, today. Chlorine is really bleach, just fancily named.

A water purifier should take out chlorine and leave the water pure and natural. Chlorine can cause a person to have dry skin, respiratory problems and, in the long run, cancer. Not all in home water purification systems take out chlorine. Reverse osmosis, for example, does not.

Several scientific studies have linked cancer and chlorinated water. There are better ways to kill bacteria in the water supply, but most treatment facilities still use chlorine, even though they know the health risks. Why? It's cheaper.

A water purifier should also remove other harmful chemicals. Herbicides and pesticides, for example, should be on the list of things that home water purifiers are certified to remove.

There are thousands of different chemicals that cause cancer, and all of them eventually end up in the water. If we remove them with the right water purification system, we have one less thing to worry about. Exposure to cancer causing chemicals is sometimes unavoidable, but we don't have to drink them.

The best home water purifier is one that balances the mineral content and pH level in the water. Minerals make water taste fresher and in trace amounts are good for our health. Without the proper pH, drinking water may be too acidic or too alkaline. Neither is good for our skin or our digestive systems.

Some water purification systems remove all minerals and leave water with an acid pH. Reverse osmosis and distillers are too examples of older water purifiers that emit acidic water.

Our body is made up of many different things, but mostly, it is water. With the right home water purifier, we can replace the water that we use every day, without ingesting chemicals and without buying bottled water, which is really just tap water that has been run through a water purification process.

Bottled water manufacturers can use whatever water purifiers they want. The industry is largely unregulated. They are not required to inform customers about the water purification process used. They are only required to list ingredients.

They are not required to have the water tested for contaminants after it runs through the water purifier. So, there is no way to know for sure what's in there.

It is known that if water is stored in the plastic bottle for long periods of time, it will absorb chemicals used to create the plastic.

Home water purifiers can also save you money. It costs much less to use a water purifier than it does to constantly buy bottled water. The cost is pennies a day, as opposed to dollars per day.

Home water purification has come a long way over the years. With today's technology, it is now affordable and effective.
