Review: They're not Berkey but they are sufficient - I returned an off-brand that I purchased cuz there's no way that they worked and they didn't come with a primer. So I repurchased these filter logic and they're not Berkey but they do work they come out a little bit faster at first but then understanding the science of them I feel pretty confident. I read not to use the red dye with these specific filters. Filter logic sent me a video of how to prime them because my faucet doesn't line up with the little washer that they send. I use a condiment bottle that you get from the dollar store that you would put ketchup in or whatever and it has a long pointed end you fill it with water and squeeze it into the bottom of the filter the little hole there and it makes it sweat it primes it it works great. The first time it came out very fast in a stream and I was concerned. I had put a second set of washers underneath where the wing nuts are and that is not advisable. Once I took them off and retightened it came out slightly slower and then I read that it's just normal for these filter logics to come out they're not exactly the same as the Berkey they do not filter supposedly as much as the Berkey mostly known for filtering chlorine. They are sufficient the water taste fine I use them for my dogs because of the chlorine hopefully fluoride is being taken from the water. Review: Great buy! - I really like these filter. I did my diy water filter project with them, they fit perfect! ## Features - Compatible models: Filterlogic black water filter can replacement for Berkey BB9-2 water filter, Berkey Gravity Filter System including Travel, Big, Royal, Imperial, Crown Series.

That is what my box says Also, there is no mention of it removing bacteria or giardia, which would be crucial in filtering non-potable water. Here is a direct quote from the Berkey water filter site. You will not see anything about these things on the FilterLogic info: Our Berkey water filter systems can be classified as a water purifier because our elements actually remove 99.9999999% of pathogenic bacteria (9-log reduction) and 99.999% of viruses which greatly exceeds the standards. **Q: Is it normal for the water to taste like charcoal for a while? It's kind of gross.** A: Mine tastes bad too! I primed the filter according to the instructions and then primed it again the next day. I just primed it again a third time for 5 minutes straight and I’m still getting the taste. The filters smell like they taste too. I never had this with another brand. Is this a fluke or normal?! **Q: What is the actual length of these filters?** A: Hi, Thanks for your interest in our filter product. The length is 9.92", thank you.
