BLACK BERKEYS CURRENTLY UNAVAILABLE

The Black Berkeys are currently unavailable as we await resolution in our lawsuit against the EPA. We're working hard to resolve this issue and will provide updates as soon as we can.

In the meantime, we recommend these highly effective ceramic filter options:

• Ultra Sterasyl Ceramic Filters: ideal if fluoride removal is not required.

• All-in-One Ultra Fluoride Filters: offers the same filtration quality as the Ultra Sterasyl but includes fluoride removal capabilities (works as a replacement for Black Berkeys and PF-2 filters combo).

They are a brand new and improved version of the original Super Sterasyl Ceramic filters that Berkey used to offer.

The Best Direct Replacement for Black Berkey Filters

Designed for the upper chamber of Berkey Water Filter Systems, they serve as a great replacement water filters when Black Berkeys are unavailable. 

They work with Berkey systems of all sizes, from the mobile Go Berkey up to countertop Crown Berkey, with difference only in the number of filters needed for the optimal flow rate. 

Ceramic filters are upper chamber elements. They do not work simultaneously with upper chamber Black Berkey purifying elements, nor do they work with the PF-2 fluoride filters. Only one technology is designed to operate in the upper chamber at a time.

Are they as good as Black Berkey filters? Of course not. But they are pretty close and can be considered the next best thing. Here's the comparison between the Black Berkeys and Ultra Sterasyl filters:

Advanced Technology Behind Ceramic Filter Candles

The Ultra Sterasyl Ceramic Filters shell in the form of a ceramic candle exhibits a strictly controlled pore structure, so as to provide efficient sub-micron filtration. It's a proven defense against hard shelled parasites, as well as other less harmful, but equally unpleasant debris, such as rust and dirt.

The bore of the filter contains granular activated carbon that aids in the reduction of chlorine and reduces organic chemicals along with improving the color, taste, and odor of the source water.

Durability, Savings and Convenience

Each ceramic filter lasts approximately 800 gallons or 6–12 months, depending on usage and maintenance. The re-cleanable design allows you to extend its lifespan, making it an economical and eco-conscious choice.

Installation is simple and can be done without technical knowledge. They are installed in the upper chamber of your Berkey system (but remember that, despite this, they don’t work with PF-2 arsenic and fluoride filters – instead, you need to use All-in-One Ultra Ceramic Candle Filters).

Cleaning is intuitive, and filter maintenance takes just minutes. 

Each element has a unique domed ceiling assuring that leakage cannot occur, which may happen with capped filters.

Priming is not required.

Pro tip: The filter needs to be kept in a place where the temperature is between 40 – 100 F for proper filtration.

How to Properly Condition for Ultra Starasyl Filters Prior to Use

Additional Notes About Ceramic Filters

Your first use of the Ultra Sterasyl Filter will be slow. No worries - this is normal. After a few cycles (after the internal carbon block is thoroughly flushed), the speed will improve. The pores on the ceramic filter element are smaller than other filters on the market (100 times thinner than a follicle of hair). This not only filters the suspended solids out of your drinking water properly, but it also allows extra exposure time to the carbon and media. The more filter elements you use, the quicker the flow rate.
