What Customers Are Saying
The product received mixed reviews. Customers found the water filter system effective at filtering water and appreciated its attractive design and good water pressure. However, many reported issues with installation, including incompatible tubing sizes and lacking instructions. Several also experienced premature failure of the filter cartridges, with the filter life indicator not accurately reflecting the actual lifespan.

I ignored a persistent leak - deciding to just live with it. But now the faucet head pops completely off. Beautiful product and high hopes but I got a dud :(

Broken registration point
I went to replace the filters for the first time and one of the filters wouldnt slot into the registration points, the second one popped right in where the first one wouldnt. when i took it down to look at it the plastic connection points were bent out of shape. Now i have to go buy a brand new system for the filters i already have and dont have clean water for the next few days. spend hundreds of dollars for something that breaks when you do an essential function is unreasonable.

Filters don't last
Filters don't last. The first set worked great and lasted 6 months before needing replacement. The second set didn't even last 2 months and water flow was just trickling. However, the light indicator still has 75% life left. The 3rd set was even worse . . . .literally watching water drip. But the filter changing light is full. What is the issue? Should I waste more money and buy another set for it to last one and a half months?

No faucet!
Product arrived late and did not include the faucet. The description and picture both clearly indicate the faucet is included. We will return it and go elsewhere.

Unbelievable
This is without a doubt the worst designed system I have ever seen. First off, shipping was terrible. Said it would arrive on Sunday, didn’t come until the following Wednesday. The included “installation kit” only contains (some) parts for a very specific hookup (3/8 inch supply – most homes I’ve owned have ½ inch), so unless you have that specific configuration, be prepared to make trips to the hardware store for fittings to get the job done. Even if you happen to have a 3/8 supply, they do not...

Easy to install and work well
Water filter works very well. I hope this product is showing in all the store because I didn’t know that it existed. Almost giving up on finding a water filter system that is easy to replace filters. I hope the product becomes very popular and continues to sell replacement filters for years to come.
Web site inaccurate
As per web site faucet compatible with the filter what i received is not compatable i had to reach to Kraus to send me a conversion kit that took a week to receive

Such a functional beauty!
We installed this faucet during our kitchen renovation and have been so happy with the dual functionality of being able to dispense both tap and filtered water in one single faucet. The pull-down capability works great when cleaning up scraps in the sink, especially when using the spraying feature. I love the matte black finish, which is super easy to clean!
