Big Berkey Water Filters

This seems to be one of the questions I receive the most. And, it makes sense because there are many ways in which Berkey Water Filters can be set up. The more you read, the more confusing it can get, and the information out in cyberspace doesn’t always clear things up. Below, I’ve assembled 7 basic facts and guidelines that will help you understand the world of Berkey.

1. Basic systems all start out with 2 filtration elements in the upper chamber. You then build upon the system from there depending on your needs and system capacity.
2. The larger the system, the more elements you can fit into the upper chamber. It ranges from 2 elements in a system like the Travel Berkey or Berkey Light, to 8 elements in the Crown Berkey.
3. Traditionally, filter / purifying elements are designed for either the upper or the lower chamber. Ceramic filters & Black Berkey filters are upper chamber.  PF-2 Fluoride / Arsenic and PF-4 Arsenic / Lead / MTBE / Fluoride filters are lower chamber. In theory, if you wanted to pimp out your Berkey, 16 filtration elements could fit into the Crown Berkey (8 up / 8 down).
4. Black Berkey’s only match up with PF-2’s, and Ceramics only match up with PF-4’s. This is because the PF-2’s are designed to complement the improved filtering abilities of the Black Berkey elements. Similarly, PF-4 filter technology is designed to complement and fit with the Ceramic filtration elements. So, if you buy 4 BB’s up top, you’ll need 2 sets of PF-2’s down below…not a PF-4 set.
5. The amount of lower chamber elements in any given system must match the amount of upper chamber elements. i.e. 2 BB’s up top must equal 1 set of PF-2’s down below, 4 Ceramic’s up top must equal a set of PF-4’s below…etc. Keep in mind, lower chamber(pf) filters are not required. A system can function with only upper chamber elements, like 2 BB’s, but not the other way around.
6. You cannot combine different types of filtration elements in one chamber. In other words, if you have 2 Black Berkey purification filters in the upper chamber and you’d like to expand to 4, you cannot add two Ceramic filters to the mix. You would need to add 2 addt’l Black Berkey filters.
7. More Filters = Faster filtration; not better filtering. If you’re buying a larger system, you most likely have a requirement for water to be available quicker and in larger volumes. In this case, you would want to opt for 4, 6, or 8 upper chamber filter elements.

Hope this gives everyone a good foundation. Couple this information with your filtering intentions and you’ll be able to select the right system and elements combination that will meet your health needs.
