Review: Great buy! - I really like these filter. I did my diy water filter project with them, they fit perfect! Review: Great Value and Taste - I purchased the Filterlogic gravity water filters as a budget-friendly replacement for my original Berkey BB9-2 elements, and I am highly impressed. The filters arrived well-packaged and fit into my gravity system perfectly with a tight, leak-free seal using the provided wing nuts and washers. Following the instructions, I flushed them for about a minute before installing. The water flow rate is steady and efficient, and the taste is identical to the original brand—completely crisp and free of any chlorine or chemical odors. Knowing that these are NSF/ANSI 42 and 372 certified for safe materials gives me great peace of mind. For a fraction of the cost of OEM filters, these provide incredible value and performance. I highly recommend them to anyone looking for a reliable alternative. I have ordered these several times. ## 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.
