Culligan D40 Level-4 Drinking Water Replacement Cartridge



Water Flow too Slow
If you have slow water flow before adding a Culligan under-sink filter, and don't need lead reduction, I'd recommend the D-30, which lasts 2-3 times longer, and has great flow. For the price of the D-40 you can almost buy 2 D-30's so you basically get about 4-6 times as much clean water for the price.

But if you've tested your water and it contains lead, I'd recommend this filter, because it is still great. It's just not as great for someone on a lower budget, who doesn't like to wait extra time for fresh water, like me.

DO NOT BUY! Doesn't work with Culligan US-600A
I bought this with the "new" improved Culligan US-600A 3/8-Inch Undersink Drinking Water Filter from Amazon because I wanted better filtration. The 600 A comes with the Culligan D-20A filter which fits perfectly with no leaks. When I installed the D-40 filter it leaked a lot and no amount of tightening could solve it. I also tried exchanging the rubber washers at the top to no avail. The D-40 and D-20 filters look to be the same size, but the D-20 has slight indentations on the bottom that allow the filter to seat properly inside the holder. It looks like the Culligan D-40 Carbon Block Filter for $31.87 could have been the correct filter, as opposed to this $27.19 filter. I don't know. I do know that I'm out about $30 and still don't have the correct filter. YUK.

Culligan Filter
I have used this product in the past. It is very easy to install,and it gives me a very satisfactory drinking water with the least effort on my part, No dripping. no sediment and the price is right.
