Question: I bought a 5 stage RO system from you guys a few years ago and I am finding some information that is a little concerning about RO systems. First, they lack essential minerals that are necessary to our health. Also, the water is very acidic water. Lastly, I read that the plastic membrane leaches toxic chemicals in the water. Not just BPA but other toxins from the plastic. Could you clarify some of these for me. I am interested in any types of filters you have that would be used with the system that I bought that would add minerals back into the water and make the water more alkaline. Thank You! -- Shea Answer: It is true that RO systems take out minerals, but using the words "essential minerals" is very misleading and most of the places you read this are from competing products... from companies who don't sell RO and try and exploit this to their advantage. There are several companies spreading fear to consumers that Reverse Osmosis water will harm their health... and you can fool some of the people some of the time! First of all, reverse osmosis removes the largest spectrum of contaminants of any water treatment process, so if you elect NOT TO use RO, you will have to settle for water that is LESS PURE. Are you OK with more cehemicals and more contaminants in the water? Secondly, water is not a SIGNIFICANT SOURCE of minerals. It is a fallacy to think that you can get even a small amount of minerals a day from the water you drink. If you drank a 55 gallon drum a day, you would probably get enough minerals, but of course you would die from Hyponatremia, which is caused by drinking too much water. You typically get minerals from your diet and supplements, especially foods that are high in calcium, magnesium and potassium... and you even need sodium. You will die without it. There are many "essential minerals" but they are not typically found in our drinking water. These minerals include the following:
