No need for expensive disposable water filters. Black Berkey purification elements can be cleaned over and over again, making Berkeys the most powerful and cost-effective systems on the market. (see Cost Comparison)

When the flow rate decreases simply brush the Black Berkey purification elements with a nylon scouring pad or nylon brush pad under running water, reinstall and your water purification system is again ready to purify water. (see User Instructions)

Each durable and efficient purification element will last for up to 3,000 gallons (6,000 gallons per set of two) and provide years of efficient water purification.

What's more, the unique Black Berkey water purification elements are self-sterilizing, which means that, unlike many water filters, there is no risk of bacteria growth inside the water filter.

  • Exceptional Performance

The powerful Black Berkey water purification elements remove or reduce pathogenic cysts, parasites, harmful or unwanted chemicals such as herbicides and pesticides, VOCs, detergents, organic solvents, trihalomethanes, cloudiness, silt, sediment, nitrates, heavy metals, foul tastes, and odors, (see Performance Comparison) yet they leave in the healthful and beneficial minerals that your body needs. (see pH Balanced Healthful Water)

  • When do I know that I need to change my water filters?

Unlike most water filters, Black Berkey elements are cleanable and they will never stop producing safe, contaminant-free drinking water.  They will eventually get clogged and flow rate will decline to the point that they must be replaced.  The particulate matter removed from the water can be cleaned on the surface of the filters, time and again, but once the sediments migrate further into the core of the filter, the flow rate cannot be restored and filters need to be changed. 

  • Will Berkey filters discharge contaminants back into the purified water when they become saturated?

The Black Berkey patented technology locks all the heavy metals, chemical compounds, and other contaminants into the filtration media in a one-way bond through two phenomena known as “adsorption” and “absorption” (See How Do Berkey Systems Work?). Water filters will become clogged with sediments well before they could ever be saturated and no longer capable of removing harmful contaminants from water.  As for pathological decontamination, the Black Berkey’s micro-pores are smaller than the smallest bacteria or virus, and as such, if the water purification system is properly installed, you never run the risk of drinking unsafe water with a Berkey system. You will just know it’s time to change your filters when the water no longer flows well through the filters, even after cleaning them.
