Black Berkey® Purification Elements are more powerful than any current gravity filter element. The unique Black Berkey® Elements are made from a proprietary blend of media designed to work synergistically and target specific contaminants that far exceed the reduction capabilities of filters that are solely composed of activated carbon or ceramic materials and are backed by independent third-party testing. 

All Berkey® Water Systems are equipped with the Black Berkey® Elements that dramatically reduce trihalomethanes, inorganic minerals, heavy metals, pharmaceuticals, pesticides, VOCs, petroleum products, perfluorinated chemicals, rust, silt, sediment, radiologicals, and more.

Considered the gold standard in gravity-fed water filtration, the authentic Black Berkey® Elements are capable of greater contaminant reduction and a longer lifespan than virtually any of the other filter elements on the market. The Berkey Filters are truly an economical choice, averaging just pennies per gallon of filtered water.

Berkey Water Filter Extended Lifetime Warranty

Wild Oak Trail offers an exclusive Lifetime warranty for your Big Berkey Water Filter.

This covers your stainless steel chamber and lid, washers, nuts and spigot. This provides coverage over and above the general manufacturers warranty. For the first 6 months to 2 years depending on which product you purchase, the warranty will be handled via NMCL (makers of the Berkey). Once your initial warranty with Berkey ends, your Berkey container and parts excluding filters will be handled via Wild Oak Trail. This warranty is provided free of charge with your system purchase through www.WildOakTrail.com. Proof of purchase through Wild Oak Trail is required. 

This guarantee will be void in circumstances of misuse. It doesn’t cover items that have been damaged due to user abuse, mistreatment, salt water or air, lack of maintenance, lack of routine cleanings, or accidents (dropping etc.).

The customer will be responsible for processing charges and shipping.

The Berkey Earth Ceramic Filters and Black Berkey purification elements have a two year pro-rated manufacturer’s warranty which is calculated in six month intervals. The filters and purification elements are not covered under lifetime warranty.  For example, if you have used the filters for 8 months, 75% of the guarantee still applies so you can get a full replacement set for 25% off of the normal cost.
