Comparison of Berkey® Systems FAQ’S
We would like to spend the
least amount of money for a system that can meet the needs of a larger
group, what would you recommend?
When determining the best size for your
situation, please consider that the larger the systems capacity, the
less often it will need to be refilled. All of our systems are available
configured with two Black Berkey Purification elements however; the four larger stainless
steel systems are expandable which means that your first consideration
should be to purchase the system, which has the capacity to best meet
your groups needs. If at a later date you determine that you require
more gallons per hour, you will not have to invest in another system,
you can simply order additional purification elements to expand your
current system. Below is a list of our various two element
systems, their capacities and the maximum number of elements each system
What is the filtration rate
per hour for the various Berkey® systems?
The chart below shows the gallons per hour
for each system, when configured with two Black Berkey purification elements and when expanded to
accommodate the maximum number of elements. Flow rates calculated
with upper chamber full to top. Flow rate decreases as water level
We are going to be traveling to a third world country and will require a system for a large group of people. Which system would you recommend?
As a rule of thumb you will need two
gallons per day per person for sustained use and 1/2 to one gallon per
day per person for short-term emergency use. The difference being
that for sustained use more water is required for drinking, cooking,
cleaning, and hygiene whereas for short-term emergency use, drinking
water alone is calculated. Please make a determination as to the number
of people within the group and whether or not the system will be used
for sustained or for emergency use, then review the above FAQ’s to make a determination as to the best system to meet your
groups needs. You might also want to consider taking several Sport Berkey filtration bottles as well. These systems
are very compact personal filtration systems and were developed for
use in third world countries. They often come in very handy when travel
requires that you be away from the location of your larger purification
What are the basic
differences between the in the Berkey Light and the other
stainless steel systems?
The Berkey Light system is designed
for outdoor use therefore it is about three pounds lighter in weight
than the equivalent capacity of our stainless steel system. The Travel Berkey system is also designed for outdoor use and is
the smallest of the stainless steel systems. It is compact enough
to fit within a suitcase because unlike the Berkey Light system,
the upper chamber nests within the lower chamber during travel. This is
the preferred system when mobility is a big issue.
The four-multi use systems are designed for
indoor everyday use so they are of a heavier construction than the above
systems but these systems can also be used outdoors or during unexpected
emergencies when a source of potable water may not be
