Filterlogic Gravity Water Filter, Replacement for Berkey® BB9-2®, Purewell® | Compatible with Berkey® BB9-2® Black Carbon Filters, Purewell®, Waterdrop Gravity Filter System, NSF/ANSI 42&372 Certified

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.

It’s going to be used for a dispenser when water is lost. Fits well and easy to install. I am going to order another set for a backup. It’s long lasting and a great filter.

These filters are the cheapest they have and they work great

These filters work very well to reduce the excessive chlorine taste that we get in our municipal water. I use these with a Berkey filter system and have had no problems. The rings fit tightly with the Berkey and they don't leak at all. The filters seem to pass the water through more quickly than the Berkey filters, but they seem to be working well. I haven't done any testing on the water coming out of the filters yet, but they water sure does taste better than prior to filtering! These filters are much more reasonably priced, too. The only reason I gave them four stars is that in my last order one came through cracked, so better packaging might be in order.

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.

You get what you pay for, yes they filter but not that well. You want them to filter slow that means more filtration. It was a mistake to get these.

Great product at a fraction of the price of other brands. Filters fast and well.

They are great, they fit my water purifier.

I really like these filter. I did my diy water filter project with them, they fit perfect!
