Culligan WH-HD200-C Whole House Water Filter System 1” Inlet/Outlet – Improve Tap Water Taste, Remove Sediment, Protect Appliances

Solid build. 4 stars only due to same as some others had complaint about threading issue. Mine encountered when screwing the 3/4 to 1/2 adapter on the outlet side. The adapter went in slanting. Take note of this, it's real.

I’m using this Culligan Whole House Water Filter System for my ice machine, and it works great! The water is noticeably cleaner, and my ice comes out crystal clear without any odd taste. Installation was straightforward thanks to the built-in bypass valve and included tools, and I love that it helps protect both my ice maker and plumbing from sediment buildup. Culligan’s quality really shows, solid construction, easy maintenance, and peace of mind knowing my water is well filtered before it even reaches my appliances. Great price and fit perfectly, Highly recommend!

Bought the Culligan as a replacement to a same sized GE unit which cracked after more than 10 years of use. It is very well made and comes with a decent mounting bracket which is a must because these types of filters are very difficult to unscrew. The bypass valve is very stiff and is probably meant to be like that because the wrench to undo the filter also has a slot to fit over the bypass valve handle. One note, on the GE filter I had to change the O-ring with every filter change because it would stretch when unscrewing the filter...not sure how it will be with the Culligan; the O-ring is much thicker...and is expensive! Culligan filters, at least on Amazon, are more expensive than other filters. Finally, someone mentioned that the female threads are plastic and prone to stripping: like all such products you have to screw it in delicately by hand as far as possible BEFORE using any mechanical tightening aid. Also remember to use a fair amount of teflon tape.

I plumbed this filter housing in and put a filter in it. I used brass fittings and went directly to PEX. No leaks and it was very easy to install. Immediately, I saw some black specks caught in the filter. None were larger than 2mm but there were a few. By day three, there were a lot more specks and I thought I could see a little yellowing of the filter. I am in it less than 2 months and the color is almost as dark as the OSB board that is on the wall behind it. I know that the municipal workers try their best and they do an awesome job with the huge systems they maintain. But pipes get old and you cannot help but get some dirt in the lines here and there. I would definitely recommend that everyone get one of these and use it. It functions very well and your peace of mind knowing you are getting cleaner water has to account for something. It will also help your other filters, ice maker, tap water, etc. last much longer.

Didn't install yet, but the only downside in it so far is the valve being almost immovable Edit: after trying this filter I have encountered an issue -which seems to be common- the top valve is very hard to turn or sometimes impossible like in my case, this is due to the lubrication being almost dry. The solution is to use food grade silicone based lubricant in the valve, for that you need to remove one screw at the bottom which will release the red button on top as well as the spring underneath, this will allow you to remove the grey plastic top where two screws underneath it; once that done the entire white part can come out for lubrication (be careful not to lose the gaskets)
