A Reverse Osmosis (R/O) system is a filtration system most commonly used for drinking water by removing sale and other substances from the water molecules. I encourage you to do some research into the subject if you decide to use R/O for your main source of drinking water. The following are some reasons why.
Unfortunately, the R/O method often removes the beneficial nutrients such as calcium and potassium which your body absorbs better from water than from any other source. You may want to look for the only type of filter recommended by the US EPA which is an activated carbon block one. These are able to remove all the main contaminants and leave the minerals safely intact.
If you’re into reducing waste of any kind you may want to know that an R/O unit delivering 5 gallons of treated water per day may discharge 40 to 90 gallons of waste-water per day through the drains it’s connected to.
Water should be an important part of your diet. As I mentioned before, I encourage you to do some research to be sure you’re not getting cheated out of the essentials you need from your water.
