The Benefits of Reverse Osmosis Water Filter Systems
Although reverse osmosis water filter systems are popular, they may not be the best for filtering your water at home. Let’s find out why.
If you’re like me, you know about the sorry state of our municipal water systems. You also may have come to the conclusion that you need to be filtering your water at home.
But now, here’s the difficult part–what type of water filter do you buy?
I just looked at Amazon and typed in “water filter” into their search box. I probably got about 100 or so hits.
There are all kinds of water filters on the market. Brita makes a best pitcher filter. There are sediment filters for your house. And, of course, a ton of filters that work through a technology called reverse osmosis.
Before I talk about the pros and cons of reverse osmosis treatment, let me talk about what reverse osmosis is in the first place.
As far as water treatment is concerned, reverse osmosis is a method for purifying water by pressuring the “dirty” water through a porous membrane. On one side of the membrane, you have pure water; on the other, you have the stuff that was in the water that made it contaminated.
At first glance, reverse osmosis looks like it might be the type of filter you would want to go with. Again, looking at Amazon, they’ve probably got over 40 or so for sale.
There are a few problems with reverse osmosis, though.
One is it’s very wasteful. You get about one gallon of clean water to every three gallons of contaminated water. That’s not good from an environmental point of view.
A worse problem, to my mind, is that reverse osmosis actually filters out the stuff you need to stay in the water! Let me explain this.
As humans, we need to drink water that’s pure, but that also has traces of several minerals that we need for good health. Calcium is a good example of a mineral our bodies need in trace amounts.
Your body needs calcium for several chemical processes, not the least of which has to do with the maintenance of your bones.
Where does that calcium naturally come from? Well, we evolved (or were designed) to get part of the calcium we need from the water we drink. The same is true of a host of other minerals.
Reverse osmosis water filters systems filter out everything! Even the minerals we need!
Not only do we need those minerals, but they also are what gives water it’s delicious, yet subtle taste.
Reverse osmosis treatment is not really the best method for home use. It’s more suited for soft drink manufacturing companies, where the taste of the drink is made by all that stuff they put in it.
