Easy install and the water tastes 100% better. You will need a ferrule for the plastic pipe if you connect it to an angle stop valve.

Water quality is great. Easy to install.

We were looking for a good water filter for our coffee bar. Installed this one under the island prep sink and is working very well. Easy to install.

I luv it ! Makes the water taste great and the coffee too. Culligan knows how to do it better!

Pretty easy to install. When I first turned on the water I had a leak. Per the instructions, I disconnected the leaking end, re-cut it, and made sure to insert it ALL the way (it goes in farther that you might think). No leaks after that! Note that the pre-cut end has a crimp. You must re-cut the end before you cut to length. Flow rate is great - same as with no filter. Minus one start because filter is not ANSI certified.

Our water tasted horrible. Decided to buy the Culligan US-DC3 direct connect under sink filter. Amazing what a difference it makes!! No more buying bottled water! Tastes great. I had a plumber friend install it so I can't comment about the ease of installation. For him it was pretty straight forward and didn't take long at all. I highly recommend this filter.

I purchased the US-DC3 Under Sink Direct Connect Premium Lead Filtration System on Amazon on 12/27/22 for $100.99. I received it on 12/29/22 and didn’t install it until around mid-January 2023. In the middle of February 2023, the cold water started to slowly come out of the faucet. By the end of February 2023, the first part of March 2023 the cold water was just trickling out and only hot water was flowing regularly out of the faucet. I was determined the filter was faulty and was restricting water flow. On March 6, 2023, I contacted Culligan about their faulty US-DC3-R filter which lasted approximately 30 days. Culligan refused to replace the faulty filter claiming it was my water quality that was the issue, not their filter. It’s funny how Culligan knows what my water quality is without requesting a water quality report. Furthermore, I guess their water filter has a problem filtering water and may become inoperative as a result. I contacted Amazon to see if they would hold Culligan accountable for selling faulty water filter on their website. Amazon refused to intercede because it had been over 30 days since purchase. I will be searching for a new under sink water filter from a company that is reliable and offers excellent customer service. Obviously, Culligan is not that company.

Installation was simple and easy to follow instructions. However, It does reduce and restrict flow through the cold water outlet. This affects and slows the cold water flow. Very frustrating. We added the filter to get rid of chlorine taste. When our pump was replaced. Reduced the chlorine on a cold water well until the chlorine was depleted when the new pump was replaced. Do to the water reduction inflow on the cold outlet, I will be disconnecting the filter. We do not have a chlorine issue since this is added during the replacement of our defective pump installation. It has been flushed through the system. Our well test concluded we have no issues with our water issues, safety, or quality.
