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.

  • Great replacement water filter for LG refrigerator
Size: Pack of 1 Style: CUL1000
The Culligan CUL1000 Refrigerator Water Filter is a fantastic alternative to the original LG LT1000 filter, providing excellent water filtration at a fraction of the cost. After using this product, I can confidently say that it delivers on its promises and exceeds expectations. First and foremost, the water quality improvement is remarkable. With the Culligan filter installed, the water from my refrigerator tastes noticeably cleaner and fresher. It effectively removes impurities, including chlorine taste and odor, as well as contaminants like lead and cysts, ensuring that every glass of water I pour is of the highest quality. Installation was a breeze, thanks to the user-friendly design of the filter. It fit perfectly into my LG refrigerator without any issues, and I appreciated the clear instructions provided, which made the process hassle-free. One of the standout features of this product is its affordability. Compared to the OEM LG filter, the Culligan CUL1000 comes at a much lower price point without compromising on performance. This makes it an excellent choice for anyone looking to save money without sacrificing water quality. Overall, I highly recommend the Culligan CUL1000 Refrigerator Water Filter to anyone in need of a cost-effective yet high-quality filtration solution for their LG refrigerator. With its excellent performance, easy installation, and unbeatable value, it's truly an exceptional product that deserves recognition. ... show more

  • Does not fit
Size: Pack of 1 Style: CUL800
Had one unit that fit in place of the LT800 filter from LG, but now have received two filters in a row that do not fit. Recommend against this brand

  • Good Replacement for LG filter
Size: Pack of 1 Style: CUL1000
I like this filter so far. The water tastes a bit different than the standard lg filter, but not bad. For the price, this filter is a way better value than the standard lg filter.

  • Awesome product!
Size: Pack of 1 Style: CUL1000
I started using these almost immediately after buying my 7G (wink) refrigerator. As states, they fit my model and I have never had a leak. They are also less money than the original brand!!! I did a lot of research and sawed a few filters in two. There is a reason that companies like Culligan advertise the higher level certifications. They have thick cores and filter more contaminates out of the water. Quality costs a little more but it is worth it. ... show more
