The system arrives with the components needed for its standard two-element configuration. The Royal can later accommodate up to four compatible primary elements.
PF-2® post-filters, stands, and upgraded spigots are optional accessories. Check the compatibility of the selected package and model before ordering.
Will the Royal Berkey® Fit on Your Counter?
Allow for a housing approximately 23 inches tall and 9.5 inches in diameter. Leave additional room above the lid for refilling and in front of the spigot for a glass. Include the height of any optional stand when checking cabinet clearance.
Compared with Big Berkey®, Royal adds one inch in diameter and 3.75 inches in assembled height. When empty, its chambers nest to approximately 15.25 inches for storage.
Royal Berkey® vs. Big Berkey®
The Royal and Big use a similar countertop format and can each accommodate up to four primary elements. The major difference is the amount of filtered water the lower chamber can store.
| Feature | Big Berkey® | Royal Berkey® |
|---|---|---|
| Capacity | 2.25 gallons | 3.25 gallons |
| Diameter | 8.5 inches | 9.5 inches |
| Height in use | 19.25 inches | 23 inches |
| Everyday household guidance | 1–4 people | 2–4 people |
| Maximum primary elements | 4 | 4 |
| Best reason to choose | Smaller footprint | About 44% more capacity |
Choose the Big Berkey® when countertop space is the priority. Choose the Royal when having more water available between refills is more important.
Need a larger reserve? The 4.5-gallon Imperial Berkey® is the next size up. Compare its dimensions before choosing a larger system.
Capacity, Dimensions & Flow Rate
| Capacity | 3.25 gallons (12.3 liters) |
|---|---|
| Diameter | 9.5 inches |
| Height in use | 23 inches |
| Height nested for storage | 15.25 inches |
| Empty weight | Approximately 8 lbs |
| Included primary elements | 2 Black Berkey® Elements |
| Maximum primary elements | Up to 4 elements |
| Flow rate with 2 Black Berkey® Elements | Up to 4 gallons per hour |
| Flow rate with 4 Black Berkey® Elements | Up to 7 gallons per hour |
Maximum flow rates are measured with the upper chamber full. Flow naturally decreases as the water level drops.
These flow figures apply to Black Berkey® Elements. Water quality, priming, and maintenance also affect flow; Phoenix replacements have separate specifications. Adding elements increases potential flow, while storage remains 3.25 gallons.
How the Royal Berkey® Works
The Royal Berkey® operates by gravity. Water entering the upper chamber passes through the installed primary filter elements and collects in the lower chamber, where it can be dispensed through the spigot.
No electrical connection, plumbing installation, or pressurized water line is required for normal operation. Fill the upper chamber and allow gravity to move the water through the elements.
Included Black Berkey® Elements
The Royal Berkey® sold on this page currently includes 2 Black Berkey® Elements.
Independent Black Berkey® laboratory documentation reports reduction performance for a range of drinking-water substances, including selected heavy metals, chlorine-related compounds, VOCs, pharmaceuticals, petroleum-related compounds, particulates, and other substances under the documented test conditions.
Because Black Berkey® Elements are not designed as a reverse-osmosis or demineralization system, ordinary dissolved minerals such as calcium and magnesium generally remain in the water.
A pair of Black Berkey® Elements has a manufacturer-recommended replacement interval of up to approximately 6,000 gallons under stated conditions. Actual service life may be shorter depending on source water quality and use.
Use the Berkey® filter test-results library to review evidence for the installed elements. Phoenix laboratory reports describe a different filter product.
Replacement Filters & Compatible Elements
The Royal Berkey® can accommodate up to four compatible primary filter elements.
Phoenix Gravity New Millennium Edition™ Elements
Phoenix Gravity New Millennium Edition™ Filter Elements are compatible with the Royal Berkey® and are currently the primary replacement option available through normal authorized U.S. distribution.

You can also visit our Berkey Replacement Filters Guide for current compatibility information.
Optional PF-2® Elements
Optional PF-2® Fluoride & Arsenic Reduction Elements can be installed in the lower chamber when used with compatible primary elements. Use one PF-2® for each installed compatible primary element, up to four on the Royal Berkey®.
With the included pair of primary filters, use two PF-2® post-filters if adding this option. PF-2® Elements supplement the primary filters and are sold separately.
NSF Certification and Your Filter Configuration
- Phoenix PGF9-2 component listing: NSF/ANSI 42 for chlorine and taste-and-odor reduction, tested to 4,000 liters for these claims.
- Royal Berkey® featuring Phoenix: NSF/ANSI 42 for chlorine and taste-and-odor reduction, with a listed 1,050-gallon service cycle.
- NSF/ANSI/CAN 372 listing: lead-content requirements for the named Phoenix-equipped configuration’s materials; this is not certification for lead removal from drinking water.
Use the Replacement Filters Guide to compare current options and their separate performance evidence.
Setup & Everyday Refilling
- Clean the chambers and applicable components according to the included instructions.
- Prime the Black Berkey® Elements, then install the elements and spigot with the supplied seals and hardware.
- Complete the manufacturer’s flushing and assembly-verification procedure before normal use.
- Place the system on a stable surface and fill with cold or room-temperature water.
Refill frequency depends on how much water you use for drinking, cooking, and beverages. Track actual daily use rather than assuming every refill equals the full 3.25-gallon storage capacity.
Maintenance & Everyday Care
- Prime filter elements according to the current instructions before first use.
- Use cold or room-temperature water only.
- Do not use salt water.
- Clean the stainless steel chambers periodically with mild dish soap and water.
- Do not use soap or detergent on the Black Berkey® filter media.
- If flow slows during the useful service life of compatible cleanable elements, clean them according to their current care instructions.
- Cleaning may help restore flow but does not reset applicable gallon guidance.
- Replace elements according to the applicable gallon guidance, water conditions, usage, and current manufacturer instructions.
The stainless steel Berkey® chambers are assembled in the USA from U.S. and imported parts. Black Berkey® Elements are made and assembled in the USA.
Red Food Coloring Test for Black Berkey® Elements
The Red Food Coloring Test can help verify that Black Berkey® Elements and sealing points are properly installed.
- Remove any PF-2® Elements before performing the test.
- Make sure the Black Berkey® Elements are correctly installed.
- Add the appropriate artificial red food coloring to the water in the upper chamber at a rate of up to 1/8 teaspoon (approximately 10 drops) per gallon.
- Allow the water to filter into the lower chamber.
- If the filtered water remains clear, the installed elements and seals have passed the assembly-verification test.
- If pink or red coloring appears below, inspect the element installation, washers, wing nuts, and openings, correct the issue, and repeat the test.
This is an installation and sealing check; it does not measure reduction of every substance evaluated in laboratory testing.
