  • ADVANCED CERAMIC AND CARBON FILTRATION: Unlike other gravity carbon filters, our carbon and ceramic water filter features both a high-grade ceramic outer shell and a filter core that is made of proprietary carbon-based granular material to reduce harmful contaminants.
  • IDEAL FOR HOME, OUTDOORS AND CAMPING: Pair with the Culligan Scout or Venture gravity water filter system to enjoy clean water anywhere, no electricity or installation required. Great for everyday use at home or as a camping water filter.

    • Works great
Size: 1-Pack
I have used 50 gallons in my culligan filter set up on the job site from hydrant water and it works great. Very slow the few weeks but if you fill it before you leave site for the day it will be full when you arrive the next morning. Water tastes great and no complaints, hoping to get atleast another 50 gallons out of it; cleaned all the brown residue off the filter once I hit 50 gallons. ... show more

    • Water Particulate HIGHER than what goes in
Size: 2-Pack
After flushing 4 gallons of water through and emptying out the bottom completely, the filtered water is 20 ppms higher than my tap water. Now I know they advertise that the filters preserve mineral content, but I’m not happy with a TDS reading HIGHER than my tap water. Too expensive to not see an improvement in dissolved particulate. ... show more

    • The best water filters around!
Size: 3-Pack
Review Image by Schlockmeister
The 3-pack is a great deal. With each filter good for 50 gallons, using 3 filters lasts for 150 gallons and filter water 3 times as fast. I use them in my Culligan silver tank, and they fit perfect. I did a water test and they do last longer than 50 gallons with wiping them periodically, so I think that's Culligan stating the most conservative use. Anyway, they filter water that tastes similar to reverse osmosis. Yes, the filters aren't cheap, but they are one of the very few options to filter out microplastics and nitrates and waste no water, unlike reverse osmosis. As long as you counter space somewhere, these work great. Absolutely no complaints for something that makes water as safe as RO for less cost and waste. And, as a bonus, you can take the tank with filters with you if you camp or have a camper. More use! Update: I also got the 4-pack and use 2 at a time, which work great for my use. ... show more

    • Worth the invesment.
Size: 1-Pack
We have had our Culligan water filter system for about a month and a half, and we are loving it! At first, we only ordered one filter, and we decided it was filtering too slowly for our needs, so we ordered a second filter, and it made all the difference. It is definitely a financial investment, but completely worth it. We were ready to get rid of the plastic filters and pitcher, and feel so much better about the water we are drinking. It also looks great in our kitchen! ... show more

    • My water tastes like nothing now!
Size: 2-Pack
I have a Berkey Light and its filters are finally done for and can’t be bought anymore. My city tap water leaves a metal taste on my tongue and smells like dirt, so I can’t stand drinking it. I went scouring to find what replacement filters I could buy to keep using my Berkey, keeping in mind price as I didn’t want to spend a fortune every 6 months, but also didn’t want cheap ones that were crap. Out of all the options I found, these were a good price and I liked that I didn’t have to prime them by trying to hook to the faucet and run water through. These are so easy to rinse the outside with the sponge they include. They fit perfect in my Berkey. I ran the 3 loads of water through and took my first sip. My water tasted like nothing! Absolutely nothing! It’s amazing! Ahhhh I am so happy! Thank you Culligan!!! ... show more

Cleans out many of the chemicals and impurities that are in our local water.. value is good they last about a year. We save so much money from not buying water and drinking out of plastic toxic bottles. ... show more
