Description

Culligan’s water filtration systems have improved water quality for thousands of families worldwide. Culligan filters reduce up to 50+ impurities including lead, asbestos, mercury, chlorine taste & odor, 8 pharmaceuticals, and cysts. Culligan filters reduce chlorine taste & odor for better tasting water and ice. They provide fresh water by also reducing select pharmaceuticals including ibuprofen, atenolol, and trimethoprim. Additionally, most Culligan filters reduce the presence of illness-causing, waterborne parasites, like Giardia and Cryptosporidium, helping you stay healthy when you hydrate. Culligan filters have an activated carbon cartridge that absorbs the carbon- based VOCs (volatile organic compounds) as they pass through the filter, resulting in better water. Culligan filters provide a compatible refrigerator fit that’s easy to install and replace every 6 months. Culligan filters are certified by IAPMO R&T against NSF/ANSI 42, 53, and 401 for the reduction of claims specified in the performance data sheet. For complete list of Culligan filters and impurities reduced, see manufacturer's performance data sheet or website for full contaminant reduction information. Substances reduced are not necessarily in all users’ water.

    • They work.
Style: CUW4
It works with no issues. And cheaper than the ones that are recommended to change out.

    • Works as replacement for whirlpool
Style: CUW4
Perfect fit for our whirlpool refrigerator. We've never had a fridge with a filter before, so when I saw how much they cost to replace, I was a bit taken aback. But, this one was cheaper than the OEM version so I tried it out and we're happy with it! Water tastes great, and upon testing the water, no harmful chemicals or metals found. Perfect. ... show more

Love this Culligan filter! I am just getting educated on all the things that can be in water including pharmaceuticals! Lead?! Chorine?? Ugh! This filtered water is so clean; great value and super easy to install.

    • It WILL leak, trust the reviews unfortunately.
Style: CUW1
Review Image by Ben G. Ben G.
Read the reviews that this product was a great replacement for the Everydrop 1 but that some of them leak horribly in certain models of refrigerators. Unfortunately it turns out ours is one of those. The design is poor for a Culligan (name brand) product. The diameter is smaller and length shorter as well as the two water ports are upside down from the factory water filters ports and finally it is missing the forward latch lock. It does “look” as it will work but it doesn’t seat right with it not being the same diameter and length as the factory ones. Thankfully because of the previous reviews we were anticipating the leaks and was ready when it started. We then reinstalled the factory one and no leaks, reinstalled the Culligan one again and it leaks everywhere so it was not an incorrect installation. ... show more

    • Works fine but a pain to install and remove
Style: CUW1
These work fine but for 10.00 more just buy name brand and not have to deal with the bracket. I suspect the reason they use the bracket is then they can reuse the same filter for multiple models. Its a pain to install and a pain to remove. If you can afford it, just pay the extra 10.00 for the proper filter. ... show more

    • Improved Water Taste and My Ice Maker Works
Style: CUW4
While I wish filters overall cost a bit less, this filter seems to be a fair price and performs the best. So certainly the best bang for the buck. I've tried other filters and brands, but this does the best of them all for my Whirlpool fridge. It improved the taste of my water removing whatever was there before. It tastes nearly as good as RO/bottled water if not better in some cases. Obviously water quality depends on your source and location, so your mileage may vary. As a side note, it fixed my ice maker PSI and it started making ice consistently. Which I suppose speaks to the quality of the filter as well. It filters well while not terribly restricting water flow. I'll be buying more in the future. If it goes on sale, I'm stocking up. ... show more
