Reverse Osmosis Filter

If you're at all interested in your health, you've probably thought about buying a reverse osmosis water dispenser. After all, of the many technologies used to filter water, reverse osmosis is one of the best known. Although, it works well, it may not be the best type of water filter for you to buy. Reverse osmosis water filtering systems have a big flaw when used to filter drinking water. Let's find out what it is!

First off, I hope you realize the need to filter your water. If not, let's go over a few facts. Our nation's water systems are horribly compromised! Studies have been done recently that have found everything in our water from pesticides to prescription drugs. Ralph Nader's group did a study which found over 2,000 known carcinogens in our water systems. Since bottled water is potentially just as polluted as our municipal and well water, your only alternative is to filter your water at home.

There are several ways to do this. You can buy a whole house water filter, a filter for a single faucet, or a water dispenser, which also filters the water. If you're thinking of the latter, then I'm sure you've considered buying a reverse osmosis water dispenser.

Reverse osmosis works by pressuring the water through a membrane. The clean water ends up on the other side of the membrane. The problem with reverse osmosis water filtering systems is it filters out absolutely everything from the water.

But you actually don't want everything filtered out!

Pure water is supposed to contain naturally occurring trace minerals like potassium, calcium, and magnesium. Without these trace minerals in our diet and in what we drink, our health suffers. So, if you're using a reverse osmosis water dispenser, you could be affecting your long term health. Scientists don't actually know what the long term consequences of drinking demineralized water is, but there's a lot of evidence that it can seriously compromise many of your body's systems.

Instead of reverse osmosis water filtering systems, you need to be thinking about other water filtering technologies that work just as well, but which leave in those very important trace minerals.

Many of the best water filters use two-step systems with carbon or ceramic filters. One step filters out the organic impurities while the other filters out the inorganic impurities. By using a two-step system you can get out all the bad stuff while leaving in the trace minerals.
