The nuvoH2O claims to produce softer water by using citric acid rather than sodium. However, experts in water technology, like Mark Timmons from USWaterSystems.com, say getting softer water from a salt-free system is impossible; the only way to soften water is to use sodium. A salt-free system like nuvoH2O produces conditioned, not softened, water.
While some may question the science, most customers who have nuvoH2O in their homes, such as those who review it on Amazon.com, are happy with the results of the system, saying they see a reduction in hard-water spots and that their water both feels and tastes better. Only a small percentage of users contend they see no improvement.
NuvoH2O claims to remove hard-water buildup in water heaters and plumbing fixtures, and to produce softer water that leaves less residue on dishes and your body. The nuvoH2O uses citric acid rather than salt to condition the water, though, and the various systems can be attached to a water supply by anyone -- no plumber needed. However, a notable number of people find the installation process trickier than promised.
Whether or not nuvoH2O owners are satisfied with the performance of their system, they all agree the customer service is excellent. Amazon.com contributors attest that nuvoH2O customer service representatives are quick to respond to emails or phone calls, and only one user (out of nearly 100) reports having trouble receiving their 90-day refund when requested. NuvoH2O even goes so far as to respond to each partially negative Amazon.com review, explaining that they "wanted to comment on your experience with us. We just recently created an Amazon.com account to respond to these types of issues."
Amazon.com contains feedback on the nuvoH2O from just over 90 customers. It scores an average rating of 3.85 stars (out of 5). More than half of the reviewers find the nuvoH2O to work as promised and are more than pleased with the customer service. Others question its effectiveness.

Mark Timmons, who has been working in the water-treatment industry for more than 38 years, addresses water-related questions on USWaterSystems.com, a site that sells water-treatment filters and accessories. When a contributor asks specifically about the nuvoH2O system, Timmons admits he has never used it, but believes the results it promises to be scientifically impossible to achieve.
