Clean water
I love these filters. Great water and fit perfect in my pro one. I rinse then run two cycles of water and they are good to go. They last about a year for me

Good Quality Water Filter
I originally purchased these filters because I was specifically looking for something that helps reduce fluoride and PFAs, and this seemed like a really good option for that. I’ve been trying to be more mindful about what I’m putting into my body, especially with water, so that was my main reason for choosing these. I have a 2ProOne G3.07 gravity water filter system and these fit perfectly and are a much more affordable option that filters out the same chemicals as the ones ProOne sells. I have not noticed any difference in water taste or smell. The installation was extremely easy and the filters themselves are durable. They function the exact same as the filters that come with the ProOne Gravity water filter system. I recommend for anyone wanting an affordable option.

Water Taste Bad
I did some research on these gravity filters because I wanted to make sure the water that my family is consuming is safe. These filters checked all my boxes with testing, certifications and great reviews. I received the filters and followed the instructions. I ran the water through them and dumped the container, cleaned it and refilled. I was excited to finally try some fresh filtered water and it tasted like dirt/mildew. I dumped the container, refilled and ran more water through the filters. Same taste. I got a hold of customer service and they were really amazing. I was told the washers were the problem and they had a new ones that they would send to me. I received the new washers installed them on the filters, washed my container out and refilled. Water still tasted like dirt/mold. Customer service sent out new filters when I told them the washers were not the problem. I received the filters and one filter is perfect and white. I open the second filter and it looks used and is wet (see the picture I have attached). I set the wet filter aside and went ahead and just installed the new looking filter. Ran all the water through it and dumped my container. The water still tasted like dirt/mold. I am sending these filters back and getting a refund. I just can't trust that I and my family are ingesting safe water. Then to receive a used wet filter as a replacement is just the last straw. I will say that Jamie was so amazing with her customer service and she really did try to make things right.

I'm very impressed
Since I've started using a gravity water filter I have wanted to try ceramic filters instead of the black carbon filters. I jumped at the chance when this one turned up on Vine and I'm glad I did. It was only one filter, but the second I saw it and read the data report on the companies website I quickly ordered another one. Unlike the generic unknown filters out there this one is made by a reputable company that actually has it's performance data sheet available online for their water filters. The list is very impressive! I couldn't be happier with this filter. I have read that even though the manufacturer recommends replacement every six months you can clean these filters and many people get a year or more out of them before replacement. According to the tests on this filter the performance after nearly 800 gallons does not drop off much at all and the majority of the things I worry about are indeed reduced by at least 95% or higher. I think that is great performance. It even removes microplastics. I am also happy to see that it reduces arsenic by 88% and that is without attaching any additional filters. Arsenic is a problem where I live, and to be honest I do worry what the additional filters might be adding to the water just as much, so it's good to know that these filters are reducing the arsenic levels that much without any other filtration. I'm impressed with the performance and quality of these filters and I can highly recommend them.

These work well for a Berkey replacement!
We bought these to replace the black berkey filters after they were discontinued. These require 1 cycle of water through them initially to clean them out. But then after that cycle, they produce really clean filtered, tasty water. They are great quality, and we have had no complaints!

Quality Filter
If it does all that is say it does, Im sold! Im using two of these in a Pro One Traveler. They are large filters, and I believe the water quality to be good. My body is very sensitive to metals, and so far the taste is very clean. We live in an area of Arizona where there is salty water, and this removes the taste. The flow is very good. Im happy to find long lasting filtration that doesn't break the bank. Thank you.

Unsure if working well
I am not sure they are filtering the water as my previous filters for the Berkey have. After only a few short weeks, the water does not taste as crisp.

Where I live the tap water is terrible, it smells like pond water
Where I live the tap water is terrible, it smells like pond water. These filters take the smell away, leaving the water tasting like it should. These filters arrived excellently packaged, well protected!

Amazing replacement filters for our Berkeys!
We own two Berkey systems and installed two of these filters in each unit (four total). Our previous filters were well past the recommended replacement time, and I could definitely taste that the carbon filtration was no longer working properly. As soon as we installed these Coldstream filters, the difference was immediate. The water tasted noticeably cleaner and fresher. I was also pleasantly surprised that we did not experience the bad or chalky taste that some other reviewers mentioned. They worked well right out of the box. So far we’re very impressed with the quality and performance. For our household, we plan to use this set for about a year before replacing them again.
