The Big Berkey BK4X2 Countertop Water Filter System is amazing!! It holds 2.25 ounces of purified water. I own this filter and can attest to the difference in how the water tastes compared to regular tap water or any of the other water filters I have tried in the past.
This filter comes with two elements that actually purify the water by removing 100% of pathogens! It also comes with 2 fluoride filters that can reduce the amount of fluoride in your water by 95%!
The system is approximately 19″ tall so it does not fit into my refrigerator. We have a place for it on the kitchen counter and it works great!
