I was worried that nothing could clean this Washingon DC water. I have a whole home 3-stage water filter system and the water still smelled and tasted terrible. I used to go to the health food store to fill up 5 gallon jugs with alkaline water twice a month which cost a pretty penny. I decided to go for the Sans and it was the best decision ever! The water tastes great and I no longer have to pay for taxis and break my back carrying water jugs. Thank you, Sans! My only suggestion would be to make the water reservoir from stainless steel instead of plastic to reduce plastic exposure a bit. That’s an add on, I would be happy to buy. But overall, I am very pleased.
