I had the water tested for impurities, chlorine, minerals, etc... We did the blind taste tests. Penta won EVERY test EVERY time. I don't care if it's $2 for a small bottle. I like it. The air around my place on the ocean in Malibu smells great. The air around my other places is fine too. I try not to spend too much time in the DC area. I'm not worried about the air. I'm too busy. I'm staying with the Penta water. You guys can drink whatever you want. I don't drink much of anything else. Maybe a little pure cranberry or fruit juice. But nothing else. My health is perfect so I'm not worried about anything....Please Register or Log in to view the hidden image!
