Think you know enough about home water filtration systems to choose the one that’s right for you? Check out these widely believed myths about home water filtration systems and find out how much you really know.

A “quality” filter will clean out all contaminants

A filter that’s perfect for one area’s water supply might not catch the contaminants in another area’s supply. Carbon filters, the most common type, filter out sediment, chlorine and mercury, but can’t remove most bacteria or radioactive compounds. On the other hand, reverse osmosis systems filter so well that natural minerals are removed, which some studies indicate can cause mineral deficiency in those who drink this water regularly.

Bottled water is cleaner than water filtered at home

Despite the fancy labels and flashy advertising, bottled water is, in fact, often of worse quality than water processed through home water filtration systems. The main reason is that chemicals from the plastic bottles often leech into the water.

You only need to filter drinking water

While filtering your drinking water should be your first concern, the water you bathe in also affects your health. Human skin is extremely absorbent and any contaminants that contact your skin during a bath or shower can soak in and enter your bloodstream.

A quality system is expensive

Some of the best home water filtration systems can be bought for less than $100. Some companies, like Aquasana, offer combo deals on tap and shower filters, which can also save you quite a bit. Look around online and you can find some good deals on excellent home water filtration systems.

Don’t let the myths about home water filtration systems put you off trying them for yourself. Learn which type of filter you need, find a good deal on a tap and shower combo package, and experience the difference home water filtration systems can make.
