Purchased the system having 7 layers of filtration, plus the alkaline drinking system. I have used two different water softeners in the past, plus an R.O. alkaline filter by itself, and this one seems very acceptable.
In my case, the alkaline filter sputters out as if there are air pockets, even weeks after installation. After making a phone call, it was explained that this has to do with the pressure, and that after a few thousand gallons, that will not occur. Meanwhile, I wait for the air bubbles to dissipate before drinking out of the glass. It is not really good to drink so much air, from what I have read. When Carla returned to test the water, it tested green. I expected it to test more on the ph side, but green is certainly better than orange!
Even with these gripes, I am very satisfied with H2O To Go. Sid is very informative; he even called me after I had spoken with a rep, to make sure I understood what was said. That is outstanding customer service. The system itself is quite easy to maintain. I would probably buy this product again.
***UPDATE: The water tastes better than ever, and the bubbles are disappearing. Also, I learned that the ppm is way under 200 ppm in the drinking water, which is the maximum count recommended for my new coffeemaker, so I am a happy camper! After all, maybe the reason some people complain about their coffeemaker breaking is the kind of water they put into it. Thank you, H2O To Go!
