Imperial Berkey Water Filter

Imperial Berkey Water Filter (4.5 Gallon System) – Ideal for 6–8 People

If you need a larger capacity water filtration system without going to the largest size, the Imperial Berkey® is one of the best options available.

This 4.5 gallon gravity-fed system is designed for families, preparedness, and anyone who wants reliable access to clean water without relying on power or plumbing.

Who Should Choose the Imperial Berkey?

• Families of 4–8 people who need more capacity than the Big or Royal Berkey
• Preppers and emergency planners who want a reliable, off-grid water solution
• Homes with higher daily water usage (drinking, cooking, pets)
• Anyone wanting fewer refills compared to smaller systems

👉 Tip: If you want fewer refills and more filtered water ready at all times, sizing up to the Imperial is a smart move.

Benefits of the Imperial Berkey® Water Filter

The Imperial Berkey® can produce up to 5.5 gallons per hour with 2 elements—and up to 16.5 gallons per hour when expanded to 6 elements.

This makes it an excellent choice for both daily use and emergency situations, where access to clean water is critical.

You can also add PF-2 fluoride and arsenic reduction filters for enhanced filtration.

Because the system is compact (under 10 inches wide), it fits easily on most countertops while still offering high capacity.

Built from durable stainless steel, the Imperial Berkey is designed for years of reliable use.

Important Note on Filter Availability

Due to recent regulatory changes, original Black Berkey® filters have become harder to find.

Many users are now transitioning to compatible replacement options like Phoenix filter elements.

These are designed to work with Berkey systems and provide a reliable long-term filtration solution.
