New Berkey systems still ship with Black Berkey elements included. For existing system owners who need replacement filters, the Berkey Phoenix New Millennium Edition is the current in-stock filter element, made by the same manufacturer, NMCL, and is a direct drop-in replacement for any existing Berkey system. PF-2 fluoride filters remain in stock and are compatible with both element types. Shop Phoenix Elements or view the full Phoenix contaminant list. The In-Stock Replacement is Phoenix While Black Berkey elements are unavailable, the Berkey Phoenix New Millennium Edition is the officially endorsed in-stock replacement, made by NMCL, and is a direct drop-in replacement for any existing Berkey system. Phoenix elements work with the same PF-2 fluoride filters. ✓ NSF/ANSI 42 and 372 Certified ✓ Independently Lab-Tested ✓ PF-2 Compatible Shop Phoenix Elements Phoenix + PF-2 Combo Black Berkey® Filter Replacement Elements The gold standard in gravity water filtration. Tested by independent EPA-accredited laboratories, Black Berkey elements reduce over 200 contaminants while lasting up to 6,000 gallons per pair, delivering filtered water for years at just pennies per gallon. 6,000 Gallons Per Set of 2 8+ Years Lifespan (2 gal/day) 200+ Contaminants Tested 99.9%+ PFAS, Heavy Metals & Pharmaceuticals Reduction What Black Berkey Elements Reduce Tested by independent EPA-accredited and NSF-accredited third-party laboratories to NSF/ANSI standards. Black Berkey elements address the broadest range of drinking water contaminants of any gravity filter on the market, including PFAS, for which the Environmental Working Group rated the Travel Berkey "Best Overall" in independent testing. 💊 Pharmaceuticals Reduced >99.9% Acetaminophen Bisphenol-A (BPA) Caffeine Ibuprofen Naproxen 🧪 PFAS / Forever Chemicals 99.9%+ Reduction PFOA: directly tested at 99.9%+ reduction (below 2 ppt, below EPA's 4 ppt MCL) PFOS, PFNA, PFBS, PFHxS + 4 additional compounds via surrogate testing, all at 99.9%+ Tested by independent EPA-accredited third-party labs Downloadable PDF lab reports publicly available EPA finalized a 4 ppt MCL for PFOA and PFOS in April 2024. Black Berkey PFOA reduction was confirmed below 2 ppt, well within compliance. ⭐ Environmental Working Group (EWG) rated the Travel Berkey "Best Overall" for PFAS reduction in independent head-to-head testing of 10 gravity and pitcher filters. ⚠️ Heavy Metals Reduced >99% Lead Mercury Aluminum Arsenic Chromium Copper 🌾 Herbicides & Pesticides Reduced >99.9% Glyphosate (Roundup) Atrazine 2,4-D DDT Lindane ☢️ Radiologicals Reduced >99.8% Uranium Plutonium Strontium-90 Cesium-137 Radon-222 🧪 VOCs & Chemicals Reduced >99.9% Benzene Chloroform Carbon Tetrachloride Gasoline Diesel Crude Oil 💧 Chlorine & Disinfectants Below Detectable Limits Chlorine Chloramines Trihalomethanes (THMs) Foul tastes and odors Cloudiness and sediment 🔬 Full Lab Documentation For the complete breakdown of all contaminants tested with specific reduction percentages, see the Black Berkey Complete Contaminant List, the most comprehensive public reference for Black Berkey lab-verified performance data.

Exceptional Lifespan & Value Unlike disposable filters that require replacement every few months, Black Berkey elements deliver years of reliable filtration with minimal maintenance. 3,000 Gallons Per Element Single filter capacity 6,000 Gallons Per Set of 2 Standard pair capacity 8+ Years Lifespan At 2 gallons per day 4+ Years Lifespan At 4 gallons per day 💰 Just Pennies Per Gallon No expensive disposable filters. No monthly replacements. Black Berkey elements are re-cleanable throughout their 6,000-gallon lifetime, delivering premium filtration for a fraction of the cost of bottled water or other filter systems. Proof of Performance: Red Food Coloring Test Watch: Black Berkey Elements Remove Red Dye Black Berkey elements are so effective they can remove red food coloring from water, a vivid demonstration of their filtration capability. This test confirms your filters are working properly and can be performed at any time. Virtually no other gravity filter can duplicate this performance. How to Prime & Clean Black Berkey Elements Watch: Priming and Maintenance Tutorial Learn how to properly prime new Black Berkey elements and how to clean them when flow rate decreases. Simple maintenance with a ScotchBrite pad under running water restores performance and extends filter life. This quick process takes just minutes and keeps your system operating at peak efficiency. Read the full step-by-step priming guide → Re-Cleanable & Re-Usable 🧽 Simple Cleaning Process When flow rate decreases, simply brush the Black Berkey elements with a ScotchBrite pad under running water, reinstall, and your system is ready to filter again. No tools required Takes just minutes Restores like-new flow rate Can be done multiple times throughout filter life 📏 Filter Lifespan Factors Actual filter lifespan depends on source water quality. Cleaner source water = longer filter life. Municipal/well water: Full 6,000 gallons Rainwater: Extended lifespan possible Turbid/sediment-laden water: May reduce lifespan Red dye test confirms filter effectiveness 🔍 Testing & Verification Perform a red food coloring test at any time to verify your Black Berkey elements are filtering properly. Add red dye to upper chamber Filtered water should be crystal clear If dye passes through, time to replace Test after cleaning to confirm restoration Add Fluoride & Arsenic Reduction 🚰 Optional PF-2 Filter Enhancement Concerned about fluoride and arsenic in your water? Add a set of Berkey PF-2 fluoride and arsenic reduction filters to the lower chamber of your system. The PF-2 filters screw directly into the base of Black Berkey elements and work in tandem to provide comprehensive protection. The PF-2 filters specifically target fluoride and arsenic, two contaminants that are difficult to address with standard carbon filtration alone. Together with Black Berkey elements, you get the most complete water filtration solution available. PF-2 filters are rated for up to 1,000 gallons per set (500 gallons per filter) or one year, whichever comes first. View PF-2 Fluoride & Arsenic Filters → Environmentally Sustainable ♻️ Reduces Waste One set of Black Berkey elements replaces thousands of disposable filter cartridges and plastic water bottles, dramatically reducing landfill waste. 🌱 Re-Cleanable Design Clean and reuse your filters multiple times throughout their lifespan.

Berkey Phoenix Filters have been independently tested for reduction across 200+ contaminants including PFAS, lead, chlorine, pharmaceuticals, heavy metals, VOCs, and pesticides. Phoenix carries NSF/ANSI 42 (aesthetic contaminant reduction) and NSF/ANSI/CAN 372 (lead-free construction) certifications, which Black Berkey does not have. For a side-by-side comparison of contaminant testing data across both elements, see the Black Berkey Complete Contaminant List and the Phoenix Complete Contaminant List. How long do Black Berkey elements last? A pair of Black Berkey elements is rated for up to 6,000 gallons total (3,000 gallons per element). For a typical household using 2 gallons per day, that translates to roughly 8 years of use. At 4 gallons per day, lifespan is approximately 4 years. Actual lifespan depends on source water quality, with cleaner source water yielding longer filter life. Can I clean Black Berkey elements to extend their life? Yes. Black Berkey elements are re-cleanable throughout their 6,000-gallon lifetime. When flow rate decreases, brush each element with a ScotchBrite pad under running water, reinstall, and the system is ready to filter again. The cleaning process restores like-new flow rate and can be performed multiple times throughout the filter's lifespan with no tools required. Are Black Berkey elements compatible with PF-2 fluoride filters? Yes. The PF-2 Fluoride and Arsenic reduction filters screw directly into the base of Black Berkey elements and operate in tandem in the lower chamber. PF-2 filters are also compatible with Berkey Phoenix Elements, so the upgrade path remains intact when switching to Phoenix as a replacement. View PF-2 Fluoride & Arsenic Filters.
