Review on Enhanced Fluoride Filtration with Black Berkey Replacement Filters by David Garnic

If you plan to use these 8 filters with the Big Berkey: Expect faster filling of the lower chamber but less overall performance per unit time e.g. B. 12 hours. If your Big Berkey has 4 Black Berkey filters in the top chamber instead of 2, the chamber will obviously hold less water; If your Big Berkey has 4 white PF-2 filters in the lower chamber instead of 2, it is obvious that the lower chamber will fill with less water. out of stock), we decided to fill the lower chamber as soon as possible. Berkey claims that Big Berkey produces 2.25 gallons of purified water = 8516 ml. (2.25 x 128oz/gal x 29.57ml/oz = 8516.6). This is without taking into account the preemption caused by filters. Here is our data (water treated with Berkey Biofilm Drops = 3 drops per 3L before addition to upper chamber): Upper chamber capacity: 6000ml. Drainage to lower chamber after 12 hours: 4500ml + 1000ml under a tap = 5500 ml. we need every 24 hours). PS Since Berkey recommends periodically emptying the lower chamber before refilling the upper chamber, the two-gallon Anchor Hocking pitcher shown in the photo provides the NEEDED parking space for your upper chamber while you empty the upper chamber. down cam. This jar is also extremely useful when performing a red dye test as it allows the user to visualize and compare the respective flow rates of each of the four filters simultaneously. The jug can tell users which of the four filters, if any, need to be refilled. As for the three stars for value, Berkey sells these eight filters for $436. The problem is that Berkey regularly sells filters without white filters, in which case some buyers might think paying the $599 premium is acceptable.
