If you're like me, you're probably pretty weary of salesmen. They would lie and cheat just to get you to purchase their products. People that sell home water purifiers are one in the same. The example that really comes to mind here are companies that sell reverse osmosis systems. Sure, having a reverse osmosis water treatment system is better than having no water treatment system at all but there are far better options out there. Here are 5 ugly lies to watch out for so you understand why reverse osmosis systems are mediocre at best.

1. Reverse osmosis water treatment systems are inexpensive. Using a reverse osmosis system may be cheaper than drinking bottled water but it is by no means inexpensive. Reverse osmosis costs 18 to 24 cents per gallon. In contrast, carbon filtration systems cost less than 10 cents per gallon. Which would you choose?

2. A reverse osmosis water treatment system removes all contaminants. Reverse osmosis systems are not capable of removing synthetic chemicals. It helps to understand how they work in order to see why that is. During reverse osmosis, water is exposed to a porous membrane under pressure. Contaminants such as minerals and organic chemicals, which are molecularly larger than water, are caught by the membrane. Synthetic chemicals are molecularly smaller than the membrane so they pass through. For that reason, reverse osmosis systems must be used in conjunction with a carbon filter. Why not just use a carbon filter in the first place? Carbon filters remove both organic and synthetic chemicals.

3. Reverse osmosis water treatment systems are convenient and easy to use. In comparison to other water treatment systems like carbon filtration, reverse osmosis systems are high-maintenance and complicated. Reverse osmosis systems require adequate water pressure and a diaphragmed storage tank and as such as very high-maintenance. They are also difficult to install. Carbon filters on the other hand can be installed in a matter of minutes without the help of a plumber.

4. A reverse osmosis water treatment system produces healthy, pure water. Having a reverse osmosis system is better than having no water treatment system at all but the water it produces actually isn't that healthy. The problem with reverse osmosis systems is that they produce de-mineralized water. Studies show that in order to maintain good health, we must drink water that contains natural trace minerals such as calcium, potassium, and magnesium. Drinking de-mineralized water can lead to multiple mineral deficiencies and an increased risk for cancer. Comparatively, carbon filtration systems remove all the bad stuff while leaving in the good stuff.

5. Reverse osmosis water treatment systems are efficient. The truth is that reverse osmosis systems are wasteful. They waste 2 to 3 gallons for every gallon of clean water they produce. They are also notorious for being slow because they produce less than a gallon of water per hour. Carbon filtration systems can produce up to 30 gallons of water per hour without wasting a single drop.

Now that you are armed with this information, make your decision wisely and carefully. There are many water filters out there to choose from but when you consider cost, effectiveness, efficiency, and convenience, a reverse osmosis water treatment system simply isn't a good choice. Carbon filtration systems are the best option available when it comes to home water filters. So get out there and find a carbon filtration system for your home if you want the best water filter money can buy.
