Product Features

The larger Imperial Berkey is ideal for medium to large families (4-8 people) who use a lot of water, and for medium sized groups, restaurants, cafes, medium-sized offices, fitness and yoga centers, clinics, and for use during unexpected emergencies.  The Imperial Berkey is also ideally suited for use at the cottage to provide clean, safe water for drinking, cooking, washing vegetables or for personal hygiene when potable water is not available.  

Constructed of highly polished AISI 304 stainless steel, this system has a storage capacity of 4.5 gallons (17 litres) and when in use, it stands 26” (66 cm) in height with a diameter of 10” (25.4 cm).  The upper chamber nests within the lower chamber for transport and stands only 17” (43.2 cm) in height.

NOTE: Stainless steel systems must be placed on the edge of a counter, or on a stool or stand, in order to fit a glass or other container under the spigot.  You may also choose to add the optional stainless steel base to your order which raises your Berkey 5” (12.7 cm) off the counter.

The Imperial Berkey comes in 6 configurations:

•         2 Black Berkey elements

•         2 Black Berkey elements + 2 PF-2 fluoride filters

•         4 Black Berkey elements

•         4 Black Berkey elements + 4 PF-2 fluoride filters

•         6 Black Berkey elements

•         6 Black Berkey elements + 6 PF-2 fluoride filters

NOTE: Increasing the number of Black Berkey elements will not change the quality of your water, it will simply increase the flow rate.  Choose more elements to increase your system’s production capacity (see How to choose my Berkey).
