Customer Review

We put this in our new house around a month earlier, and we love it so far. Because of the built-in refrigerator/freezer, we don’t have “easy” access to purified water in our new place because of the built-in refrigerator/freezer. Fortunately, our kitchen had a veggie sink that was easily available and perfect for filling our water bottles.

It’s simple to set up. After putting it up, all you have to do now is maintain it and change the filters every six months. Considering how much you could have spent on something that would last longer, the pricing makes it more like a fantastic deal. You’ll have to stick with this brand, which is more expensive, and I have no plans to use third-party products.

It took me about 40 minutes to finish the installation, but I double-checked every connection. Because I don’t want my new house to be flooded with water, the day we moved in! It was incredibly straightforward to set up.

According to a recent test, my drinking water contained significant lead. To solve this, I bought this filter. I chose to use this as the filter for my refrigerator. The refrigerator dispensed ice and water.
I previously had a carbon filter in the fridge, but it wasn’t certified to eliminate lead. Now I’m confident that the water and ice in my refrigerator are lead-free.
