Royal Berkey® Gravity-Fed Water Filter - 3.25 Gallons
Royal Berkey® Water Filter System – Built for Higher Daily Water Use
The Royal Berkey® Water Filter System was designed for households that use more water.
Some families don’t just drink filtered water — they cook with it, brew coffee with it, fill sports bottles, hydrate pets, and keep extra on hand. If you find yourself refilling smaller systems too often, the Royal Berkey® offers the added capacity and output to keep up.
With a 3.25-gallon storage capacity, it reduces refill frequency while maintaining the same trusted gravity-fed performance Berkey® systems are known for.
*Due to state regulations, this product is not available for sale in California or Iowa.
Designed Around Real Household Demand
The Royal Berkey® comfortably serves 2–4 people for everyday use, but its real strength lies in its efficiency.
Compared to smaller models:
-
Fewer refills throughout the day
-
Greater water availability during gatherings
-
More practical for active families
-
Better suited for higher hydration needs
If the Big Berkey® feels slightly undersized for your lifestyle, the Royal often becomes the natural upgrade.
Capacity & Output
Storage Capacity: 3.25 gallons (12.3 liters)
Diameter: 9.5"
Height (in use): Approximately 23–24"
Height (nested for storage): 15.25"
Weight: 8 lbs empty
Flow Rate
-
With 2 Black Berkey® Elements: up to 4 gallons per hour
-
With 4 Elements installed: up to 8 gallons per hour
This makes it one of the highest-output gravity systems available for home use.
Flow rate is calculated with a full upper chamber and naturally slows as the water level drops.
Expandable Filtration Power
The Royal Berkey comes standard with:
-
Expandable to 4 Black Berkey® Elements
Each element is rated for approximately 3,000 gallons, meaning a standard 2-element configuration provides about 6,000 gallons before replacement is recommended.
Optional PF-2™ Fluoride & Arsenic Reduction Filters (up to 4) may be installed in the lower chamber to reduce fluoride.
What Makes the Royal Berkey® Different?
All stainless steel Berkey® systems use the same filtration elements. The difference is in capacity and efficiency.
The Royal Berkey® is ideal for:
-
Families that cook frequently
-
Athletes or high-hydration households
-
Homes with pets
-
Entertaining guests
-
Shared housing or small offices
It’s the “middle ground” system — larger than the Big Berkey®, but not as tall or commercial-sized as the Imperial or Crown.
Built for Long-Term Use
Constructed from highly polished AISI 304 stainless steel, the Royal Berkey® is designed to withstand years of daily use.
It operates without:
-
Electricity
-
Plumbing
-
Complex installation
Just pour water into the upper chamber and let gravity do the work.
