The water tastes great and it fit nicely under the sink, but not a big fan of the faucet.

What a difference to not smell chlorine when you bring your glass to your mouth. So far the quantity of water and the quality of water are both excellent.

I just installed the system and am quite pleased so far. My tea taste even better than the jugs of water I made it with at Wal-mart.

Very pleased with this water filter system. It saves us money and I feel good because I stopped using all those plastic bottles. The taste of the water is great.

The system was sitting in my wishlist for about year or so and I finally decided to buy it for my husband's birthday. It definitely improved the taste of our water and the knowledge that our drinking water is truly safe to drink is very comforting.

I like these filters a lot, they do a good job and are super easy to replace. My wife has multiple chemical sensitivities and this filter works very well for her. I like to keep a spare set on hand and then when I replace, simply order a set immediately for the next time.

This is the second CU-A4 system that I have put into two different fifth wheels and they are great. Most tap water taste so bad to me I can’t stand to drink it, but these purification systems are great and works great in a RV. I highly recommend to everyone and especially RVers.

Our faucet stopped working. Contacted support and Francis quickly diagnosed the problem and sent us a new faucet. Easy fix. System is working again. Great customer service!

I was very impressed at the quality of the parts that came in the kit. The faucet was well made and was very pleasing in its shape. The filter unit was easy to install and very easy to hook up. I had to change my cold water valve to allow for room to install the shut off valve. The instructions were precise and easy to follow. I made a mistake when I ordered the ice maker kit as it will not work with the faucet assembly. Lucky for me I reached Nick at customer support who explained the process to get the ice maker kit to work. He has shipped the necessary parts so I can finish the install. This is exactly what customer service should be and my thanks to Nick for taking care of my problem

So far, my wife and I both love this filter. If you are physically able to climb under a sink, the install is very doable, if you take your time and follow the directions. I, unfortunately, had to hire someone to install ours because I am physically unable to climb under a sink. Two things you might wish to consider: I got 3 plumber bids quoting between 3 to 4 hours at $400 to $600 to install. That seemed like way to much so I spoke with our handy man and he was able to install it per the directions in about an hour. We did run into one issue that occurred when he tied it into our refrigerator's ice/water dispenser. The sink tap that comes with the cu-a4 needs to be swapped out with a non airlock tap if the filter is going to feed both the sink and refrigerator. The cu-a4 ships with an air lock tap. I bought the ice maker kit and the pressure step down valve at the same time as the filter but I missed the part at the end of the filter's description on Amazon that said I needed a no air lock tap if I was hooking up both a sink and refrigerator. My handy man spoke with Nick at ISpring who answered his call promptly and recognized the issue immediately. He mailed me a no air gap replacement tap with a return label for the original one.. Our handy man is coming out this week to swap out the taps and we should be good to go. Thank you Nick for your kind and speedy response!
