Clean water

Review by Dana M. Kerce 8/6/26

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

Review by Charmander 7/1/26

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.

Numbers and water are good

Review by Doug R 6/23/26

I have a Berkey water filter and the black filters and chemical filters have become harder and harder to get. On top of that there are a lot of knock offs from China. I switched and started using a ceramic filter by ProOne. I really like those filters as the chemical removal is part of the main filter. These seem to be nearly identical to those ceramic filters and the numbers on the filtering look really good (published numbers, I did not have testing done). These filters fit perfectly with no issues. I like the packaging as it seemed to protect them well in shipping. The water is filtering at about the same speed as the other ceramic filters. Our water regularly smells like pool water at its best, at it's worst it smells like a treatment plant. After filtering the water smells clean and tastes great. In my experience the ceramic filters last far longer than the old black filters so there is a lot more value as you can use them longer. The price on these also seems slightly lower. Add to that they come from the UK which makes me feel a lot better than something unknown. I will buy these again when I need a replacement.
