The Imperial Berkey Water Filter is one of Berkey’s bestsellers, and it’s become synonymous with clean drinking water.

The 4.5 gallon water purification system has several features that make it appropriate for use in different situations, so while it’s something you can depend on at home, the Imperial is just as reliable when you’re on the road.


The Imperial Berkey system comes with 2 Black Berkey Purification Elements, and in most cases these will suit users just fine.

The contamination level in water can vary however, so if that’s the case you can add up to 4 or 6 elements. Installing the filters is very easy so addition and removal is straightforward.

Just like the other Berkey systems, the Imperial is built of polished stainless steel and is only 26 inches tall.

With its 4.5 gallon / 17 liter capacity, the Imperial is more than enough to meet the needs of medium to large families. Weighing 10 lbs. when empty, the system can serve 4 to 8 people.

The system includes a rubber gasket, a priming button, 2 wing nuts, 2 washers, a stainless steel lid, and the 2 Black Berkey Elements.

Benefits of the Imperial Berkey Water Filter

The standard Imperial Berkey Water Filter system is capable of producing 5.5 gallons (20.8 L) of filtered water per hour, but if you expand the Elements to six the Imperial will generate up to 16.5 gallons (62.5 L) of pure, clean water per hour.

Furthermore, the Imperial allows you to install PF-2 arsenic and fluoride reduction filters inside the lower chamber.

Because the Imperial is compact (less than 10 inches wide), you can put it on your countertop and it won’t take up too much space.

The fact that it purifies water quickly is a plus especially if there’s an emergency or if you want to purify the water coming out of your well.

Because the system is made from stainless steel, expect the Imperial to service you for years to come, and given the company’s reputation for reliable products, the Imperial should work fine even if you use it on a regular basis.

Finally, Berkey designed the system in such a way that it only removes the pathogens in water without eliminating the nutrients.


Imperial Berkey filter reviews have been mostly positive, with the majority of customers expressing satisfaction with the way it purifies water.

Kim of Ohio posted a review of the Imperial online, saying that water is not just cleaner but tastes better, statements that were echoed by Jodie of Milwaukee and Sara of Detroit among many others.


The Imperial Berkey Water Filter is second only to the Crown in terms of capacity, so if you don’t need a unit the size of the Crown, the Imperial will do. Easy to use and practical, it’s a system you’ll want to have around not just for emergencies but for purifying the water you drink every day.
