Purewell PF-3 Black 3-Stage Composite Purification Elements, Replacement Filters for ProOne® and Berkey® Filters, ProOne® or Berkey® Big+ Water Filter System and Purewell System (2 Pack, K Series)

THESE FILTERS FIT AS HOPED IN MY BERKEY .When I installed the 4 filters , I found it helpful to use a thick dish-towel and lay it under the filter I was installing in the top water chamber of the BERKEY. I rotated the top chamber until the filter to install was the bottom of 4 filters to install in the chamber. The dishtowel raises the new enough from the chamber wall to allow me to get the filter bottom threads to align and seat in the bottom of the chamber, making threading the locknut simple.

Extremely good costumer service. The filters I purchased didn’t taste right so with just one email to purewell I was sent a new set of filters at no cost.

I tried using some off-brand water filters before, but they just don’t compare. These authentic Purewell filters are so much better. The water tastes cleaner, and the filtration process is super fast. I’ll definitely be sticking with this brand from now on. Well worth it!

Good value for the money, second time purchasing this product, works well, good quality

Great filters that function perfectly.

I ordered the filters for my purewell water purifying system to replace the used ones. The filters were defective. Reordered the same brand of filters to find out the filters were defective as well, the water wouldn't filtered through the opening which was closed.

Prefect fit and easy and fast installation.

Just bought these when we bought the Purewell 8 stage filtration system to have on hand. The ones that came with it are exactly the same.
