Ordered this filter for our office, where we have 10 or less people in the office. After using this system for 4+ months, I can say that it is among the best I've ever tasted. We have people that work outside, and they bring their jugs of water in just to fill up with our water, after discovering the difference between filtered and bottled water. We've stopped buying bottled water, so the impact on the environment is better; not to mention less exposure to BPA!

The water is crisp, refreshing, and I've noticed a difference in the way I feel after drinking it all day. It tastes alive, and extremely smooth.

I actually did a taste test comparison with a couple guys. We tasted water direct from the tap (disgusting), bottled water, water from a gravity filter (zero water), and water from the ULTRA system.

The results:
Tap: tastes like poison that should not be consumed by humans.
Bottled: tastes okay, but missing "something." Water doesn't taste "alive"
Zero water: Clean, crisp, but also missing something. Water tastes clean, but dead.
ULTRA: #1 choice. Clean, crisp, refreshing, and revitalizing. This is how water should be!
