Great product. The filter sputtered a bit when first installed but after I ran quite a bit of water through the filter it quieted down and now works like a charm.

This is the 3rd time I have purchased this product and I'm very happy with the results of cleaner water. We have well water and a full house water filter on our home, but this product is extra filter for our drinking water.

Water tasted better than the cheaper filters. Used those cheaper ones with no luck, terrible tasting water and ice. Price is on the high side, but offsets the cost of buying bottled water. Let's see how long this will last.

The Whirlpool filter 4 fits well and is working great! I will reorder from Clatterans.

Works great, fits my KitchenAid fridge perfectly. Takes few minutes for it to start working. Once it does, the water tasted great without any issues.

I didn't realize how badly I needed to replace my filter. Thank goodness I ordered this. I won't wait so long next time. It went in super easy too.

This filter is much better than the old one. We have very hard water and I noticed as soon as we replaced it how much more it filtered out. With the old filter, you could still see some of the sediment floating in the water even after it was filtered. With this new filter 4 it must have removed more.

Good fit and no other filter comes close to removing all the things this does. Likely you don't have all those things in your water, but for something I change once a year and my whole family drinks from it, why not get this?
