It just works!
[This review was collected as part of a promotion.] This filter was an easy click and play! Works great as a replacement for the OEM filter I currently had in my fridge. It's great that they can break from the mold and make something great, that works great. So far, this thing is holding up well and producing great water.

Good filter
[This review was collected as part of a promotion.] Seems to do what it says it does and filters the water. Felt pretty well made when I took it out of the box and put it in easily. Looks nice and can be used on many types of refrigerator.

A good filter
[This review was collected as part of a promotion.] This water filter came at the perfect time! Our water is very hard and needs filtered. This filter is very durable and easy to store. The only downside is that I had to run quite a bit of water through it before it started tasting filtered again. Overall, I am pleased

Great filter!
[This review was collected as part of a promotion.] Culligan’s Water Refrigerator filter was very easy to install and fit perfectly on my Whirlpool refrigerator. So far, I am very satisfied with the results as I think it the filter does its job very well. There is no filter tasting on the water. As any replacement filter, it is important to flush the initial water once the cartridge is switched. The directions recommends around 4 gallon, but at least for me, the water was already clear after flushing about 1/2 gallon. Definitely a nice alternative instead of buying the brand name.

Great affordable filter
[This review was collected as part of a promotion.] This is just like the whirlpool filters. It was just as easy to install. The water tastes fresh and clean like the official filters. The price is better, too, so I plan on using these in the future. This model is slimmer than the ones I have previously used, so I can store them without taking up a lot of room in my cabinets.

Great tasting, filtered fridge water!
[This review was collected as part of a promotion.] I was so excited to see a water filter besides the one that I use, which is namebrand and seeing a cheaper option that works just as well definitely great to use for water that can be hard and full of sediment. I absolutely love the flavor of the water that is dispense from my fridge, it taste pure and I can definitely say that it’s because of this filter.

Great filter
[This review was collected as part of a promotion.] I’m so glad I was able to get this product to sample as it was time to change the water filter on my fridge and it was a winner. I liked it the water didn’t taste bad or had a smell while using the product and the process is very good compared to the other brands I used to buy in the past. I’m very satisfied and will be repurchasing

Great water filter
[This review was collected as part of a promotion.] I have a whirlpool refrigerator that uses Everdrop 4 water filters. For my honest review, Influenster sent me a Culligan water filter that fits my fridge. It came in secure packaging with an inner plastic seal. It was super easy to install and fit perfectly. I am super happy with this filter. I highly recommend it.
