Culligan US-600A Under Sink Drinking Water Filter System - Includes D-20A Filter Cartridge

We had an older Culligan under sink filter set that used 2 cartridges and fed a dedicated cold water tap for drinking water. I had been buying Pentak brand filters for it. Last replaced about a year ago. Went to order replacements as it was due. The filter set was discontinued by Culligan %26 Pentak. I could not find anyone that offers them as a set, only the carbon filter. I realized I did not need the filtering capability of the 2-filter set as we have public water that is healthy. Just need the carbon filter to remove the chlorine taste. This filter fits the bill. Installation was easy and we kept the existing drinking water tap on the sink. I did have to buy (2) John Guest 3/8" to 1/4" reducers for the tubing as the new filter is plumbed for 3/8" tubing and the valve the old one tapped into and the tap are 1/4". No big deal. The flow rate is excellent (much better than with the old 2-filter setup) and the water tastes good. In addition, the replacement cartridges are readily available and inexpensive compared to what I was paying before. Mission accomplished.

I put this one in for a friend but i have own the same one for years and it does a great job. I have a water tester and it greatly improves the water but the clarity and taste says it all. We love it.

I love this! My water tastes so clean. It was so easy to install. A lot easier to use then my Put her water purifier

This under sink water filter system is well constructed and easy to install. I also upgraded it with a Culligan D-40A filter cartridge to filter out 99% of heavy metals like lead and mercury.

A good quality product at a good price

We have well water and this helps it become cleaner to drink. Though the well feeds the whole community. So if the water main ever is shut down or broken the filter needs to be switch more often.

I've used a bunch of different kinds of fillers in it already, and don't, none of them really filled-out nothing. I test the water I haven't had no luck, it might get the chlorine out. It's still still got the same parts per million totally dissolve solids.

I was going to return and forgot before the time frame ran out. It does not include the appropriate hardware to connect to cold water line on sink, so I couldn't even try it. It would work great for refrigerator water line, but I do not have a fridge with a water/ice dispenser.

it didn't work with my plumbing so i had to return.

will not work with my pipes.
