NSF/ANSI 42&372 Certified Water Filter Replacement Compatible with Berkey® BB9-2® Black Filters, Gravity Filter System, Purification Elements Compatible with Travel, Large, Royal, Crown Series, 2 Pack

These seem to work just fine. We can't taste any difference from the original filters. We haven't done the dye test, but I'm not sure if we want to do that just because it is a hassle. The water certainly passes through much quicker than before since our old filters were 5 years old.

I found this product and said what the heck I will take a chance. Seemed a bit unreal that I could get these for my Berkey for the price. I received them using the "adapter from Berkey to prime the new filters." I ran water through them 3 times before using the filtered water for human consumption. The water tastes delicious. I can not tell the difference from the original Berkey black filters, other than the price:)Highly recommend this product if you have a Berkey with black filters especially if they are running slow.I will buy another set when needed.

Perfect fit for travel size Berkey

The water flow is quicker than the original Berkey filters. Assuming the filtered water is as it should be. It tastes good and free of any chlorine taste .

These are great water filters. With the uncertain times we are facing. It pays to have a way to filter your water. Who knows when you will need to filter your water. The price on these filters is great as well.

Tested these against Berkey black filters, using same size water systems (BB) both with new filters, no variance in amounts of water used or it’s origin.After 1 month, filtration slowed down drastically with these filters to maybe only filtering with top half of filter. Water has to be filled to the brim in order to get any filtered water at all from these & takes hours (yes plural) per 1 gallon.Berkey filters in other water system still rocking on, full filter filtration, no noticeable slowing per gallon. The last set of Berkeys lasted 2.5 years. I’ve had a Berkey for 9 years, so yes I know what I’m talking about.Can’t recommend due to a huge difference in quality.

Bought these to replace my higher end filters. So far can’t tell any difference whatsoever! Will absolutely purchase again!! Water taste delicious!

My personal review for what it's worth,I purchased these water filters because the original OEM water filters from the manufacturer are so expensive that it forces me to look elsewhere because of my budget.That being said, there are a lot of sellers out there that sell water filters that are pure junk and you have to be very careful especially when you're filtering water through something that you're going to be drinking.I am not a chemist and I have not had the water examined for contaminants or anything else. This is just my opinion based on what I have found so far when using these filters.The filters seem to be made as good a quality as the OEM filters at a fraction of the cost as mentioned the OEM filters are hundreds of dollars And these are a fraction of that cost yet I find after priming them like you do with all filters for this unit that they produce the same taste and quality of water at the same flow rate as the original OEM filters and so that and also the fact that they are according to the manufacturer's descriptionNSF/ANSI Certified and I have no reason to doubt that statement from the manufacturer of these filters.And since I have had these now since September 2nd 2024 when I originally placed the order on Amazon I've had a chance to use them for a while and if they continue to work as well as I have I am definitely going to be buying again from the same seller in the future.Best regards from Kenai, AlaskaDon B.
