Fluoride and Arsenic Filter NSF/ANSI 42 Certified,Replacement for PF-2® Fluoride Filters,K5366 Replacement for Berkey Fluoride Filters Compatible with Berkey Gravity Filtration System-Pack of 2

Arrived on time. Consistent quality l.

I bought these to replace the filters in our Berkey. They seem to work really well. I can not tell the difference between the water filtered by the original filters and these replacements. These filters really do work for taking the chlorine taste out of our tap water. We use our Berkey all the time!

Love this product already! Was looking for this filter to add to my Berkey water filter and noticed this brand to be a lot cheaper than the one Berkey sells. I was skeptical to buy since it wasn’t from the brand itself but it looked identical and the numbers on the filter were the same so I gave it a shot. It connected perfectly to my other filters in my Berkey and has definitely made the water taste better even my husband noticed a difference!

I took the filters out of my Berkey to clean the system after 6 months of use. As I was screwing the fluoride filter back to the black filter to reassemble it, the plastic screw snapped off the black filter. Seems low quality to me, and I’m not sure how to continue using the filters. My husband is trying to glue it back on, but it seems precarious. I can’t find a way to contact the seller to ask for help. The water tastes great and filters reasonably fast. Sometimes it goes very slow in the last 40% of the black filter height, and rubbing the outside of each filter seems to help speed it up.

We use this to filter the minerals out of our tap water... well water that is... so that I can get more than one day of coffee out of our coffee maker. Without this filter, it clogs up in 2 days. With it, so far, we have been using the pot for about 3 months without having to clean the water tank and tubes. Water tastes good to. We go through about 2.5 gallons of water a day with it. So far, so good. I'll change this review if these filters fail after a years use; they are good for 30k gallons of water. We use... maybe that in the course of 2 years. I'd be very pleased with over a year of clean water!

I ordered these for the first time as an alternative to the Berkey brand. But, the cheapness is obvious. They worked for a few days and then stopped filtering. I re-primed them a few times over the next week, and after 1 day they stop flowing. Junk!

Finest water ever Berkey been using 18 yearsin

Definitely cleared the Denver tap water!! I could tell bc we use it in our tea kettle and when you boil the water a few times it will start to get a calcium deposit and some kind of clear glass floating in the kettle... After installing the filter the water stays clear until it’s about time to change the filter again. So it definitely helps!! It does last just about 5-6 months if you wash it regularly annd ant end of life the bottom of the filter kinda turns brown and it rubs off on your fingers which is quite gross. And it fits in my 1.5 gallon berkey.
