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.

Works great, removes more than sediment & you really have some clear, clean tasting water. My coffee has never been better!

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.

The filter is great, and the convenience of the system is fantastic for under-sink installation. I'm on an old water line with limited pressure, and the filter cuts my flow rate by 1/2. It's not a design flaw, but it is a consideration for purchase.

We have used the Culligan D40 cartridge for many years. Living in Los Angeles our water is not the best so filtration is necessary. We have not had any slow flow issues like others have commented until this last purchase. My husband replaced the cartridge like he always does, but this time the flow was down to a trickle. For a week we waited and waited to fill a glass of water from the fridge water/ice dispenser and I was so frustrated. I finally told my hubby to remove the cartridge and I was going to send it back as defective. This has never been the case with previous D40 cartridges we have replaced. They always work fine, have a normal flow and the water tastes great. As my hubby removed the cartridge he looked at the hole at the top and said, " this is way smaller than the other one", then he flipped it over and found he had installed it upside down. He put it back in the correct way and "viola", it worked perfect. Water flow was back to normal, the water was totally clear and free of any taste, and no more issues with the cartridge. So, just an FYI, make sure you are checking to make sure it is installed correctly and not upside down.

Excellent filtration, water taste improved dramatically. Water flow is good, but obviously it is decreased. Very happy overall with cost, shipping and performance.

My rating is low because of the flow rate. I previously used a D20. It flowed faster but filters less particles. Water trickles with the D40 cartridge.
