I've purchased the D40 filters in the past. They are good to reduce lead and other major contaminants in the water. However, the water flow is quite reduced due to the extra level of filtration. They only last for 4 months and the flow decreases as you use the D40.

In contrast, the D30 lasts 12 months, still has a great filtration profile, and the water flow is much faster and easier to cope with. In fact, I can hardly notice any difference between the hot water and the cold water now, compared with when I had the D40, and the cold water was annoyingly slow.

I recommend this filter over the more expensive D40 for everyday use, unless you have tested your water and found it to have lead. Then I'd use the D40 for health reasons, but not until then. There is no added benefit to the D40 in terms of water taste, or protection from microorganisms, compared with the D30.

Culligan screwed this one up. The original D-30 worked perfectly with my new-ish (2009) under-sink filter housing. However, the D-30A leaks, makes a loud humming sound, and reduces the flow of water to a trickle. I cannot find ANY D-30's anywhere, not at any of my local hardware stores, nor online. In desperation, I compared the new D-30A filter to the old D-30 filter I was replacing, and found that the hole in the top was significantly smaller in the new filter. I used a 5/32 drill bit to enlarge the hole (holding the filter upside down so plastic shavings would not fall into the filter) and installed it. Lo and behold, no more leaking, no more loud noise, and water flow is back to normal. My theory is they used a cheaper, less effective filtration material, so had to reduce the flow significantly in order to achieve the same filtration specs. This means I'm probably not getting the same level of filtration as before with the original filter, however I cannot taste the difference, and the alternative is replacing my Culligan filter with something else.

Culligan Drinking Water Replacement Cartridge Carbon Block, 0.5 Micron, 1,000 Gallon Capacity #D-30

The D-30 cartridge severely restricts water flow and nowhere on the packaging does it indicate this. I had to return them to amazon for a refund. Am using the D-10's with no noticeable reduction in water flow/pressure. Suugest that Culligan come up with some indication of water flow for each of their water filters. If water flow is not an issue for you, then the D-30's are probably fine.

The water flow through filter was completely unacceptable. Had to use original filter, which was fine. As other reviewers noted, may have to drill a large hole to increase flow. The product description should indicate that reduced flow is the price to be pad for increased filtration. Small hole also creates increased back pressure that leads to leaks.

Water tastes about the same to me as it did with the D-20A, but the water flow is less than half of what it used to be. I can live with a small reduction for healthier drinking water, but this was too extreme. Going back to the D-20A.

This product is the most cost effective among the Culligan home water filters. It last 1 year (or 1000 gallons) and performes well.

As several others have pointed out, the newer revision of this filter has a very small outlet hole in the top that reduces the water flow to about 1/3 of that of the unfiltered water flow. My best guess is that this was added to allow the filter to qualify for the level 2 filtration value. I am primarily trying to get chlorine out of the city water, so I drilled a 3/16th hole to replace the one that was present. Now I get more than 80% of the water flow that I did before the filter was added and I still have no chlorine taste in the water.

Note: these filters have to be run for several minutes after initially installed to get the grey gunk that is used to line the inside (carbon, I assume) out of them.

I have been using this product for many years and have had great results. I have this item under sink and lasts for a complete year of great tasting drinking water, better than bottled water.
