What size
Berkey system would be best for my needs? After years of customer-feedback and field testing, we found that if you take the flow rate of the
system and multiply that by the holding capacity, this number is a good indicator of the maximum number of people that each system would support under normal conditions. Use this chart as a guide line.
Please note that the # of times to refill can become an Inconvenient Truth. |
