Specific NSF-Listed ConfigurationsCertification is tied to named Berkey® systems featuring Phoenix. Is Phoenix Gravity the Replacement for Black Berkey® Elements? Yes—as a current compatible replacement option. Phoenix Gravity New Millennium Edition™ Filter Elements are designed to fit Berkey® gravity-fed systems and are currently the primary replacement option available through normal authorized U.S. distribution for customers who previously relied on Black Berkey® Elements. However, Phoenix Gravity elements should not be described as simply renamed Black Berkey® Elements. The media formulation, designed gallon capacity, flow characteristics, laboratory documentation, and certification status differ.

Premium CTC-60 coconut-shell activated-carbon-based media Approximately 2,750 gallons of designed capacity per element Approximately 5,500 gallons of designed capacity per set of two Up to approximately 4.2 gallons per hour per pair with a full upper chamber Independent laboratory testing for multiple drinking-water substances Compatible with Berkey PF-2™ Fluoride & Arsenic Reduction Elements Designed to retain ordinary dissolved minerals such as calcium and magnesium Not designed to significantly lower TDS Re-cleanable during useful filter life One-year limited warranty NSF Certification: Exactly What Is Certified? Current NSF-listed Berkey® configurations: Travel Berkey®, Big Berkey®, and Royal Berkey® systems featuring Phoenix Gravity New Millennium Edition™ Filter Elements are currently listed to NSF/ANSI Standard 42 and NSF/ANSI/CAN Standard 372. NSF/ANSI Standard 42 For the currently listed Travel, Big, and Royal Berkey® configurations featuring Phoenix Gravity elements, the certified Standard 42 claims include: Chlorine reduction Taste-and-odor reduction Standard 42 addresses aesthetic effects. It should not be interpreted as certification for every substance evaluated in separate Phoenix laboratory reports. NSF/ANSI/CAN Standard 372 Standard 372 addresses lead-content requirements for drinking-water system components and materials that contact water. Standard 372 is not a lead-reduction performance certification. Lead-reduction testing, where discussed, comes from separate laboratory documentation and should be evaluated on its own test conditions. Certification scope matters: Do not assume that every Berkey® system fitted with Phoenix automatically carries the same system-level certification. The current NSF listings specifically identify Travel Berkey®, Big Berkey®, and Royal Berkey® systems featuring Phoenix Gravity New Millennium Edition™ Filter Elements. Phoenix Gravity Laboratory Reports Yes—laboratory documentation belongs on this page because test evidence is one of the most important questions customers have when comparing Phoenix Gravity with Black Berkey® Elements and other replacement filters. Rather than reproducing every report in the product description, this page summarizes selected results and links to our dedicated test-results library where customers can review the available documentation in greater detail. Review the supporting documentation: Visit our Phoenix Gravity Test Results & Laboratory Reports page for available independent laboratory reports, contaminant-specific results, and additional testing information. When reviewing a laboratory result, pay attention to the substance tested, starting concentration, reported result or detection limit, test conditions, and the number of gallons processed. Results from different laboratories or protocols should not be treated as directly interchangeable. See the Phoenix Gravity Laboratory Reports Review the available test documentation and contaminant-specific results behind the performance information summarized on this product page. View Laboratory Reports & Test Results Independent Testing: Separate From NSF Certification Phoenix Gravity elements have also been evaluated in separate independent laboratory testing for substances outside the limited scope of the current NSF-listed claims. Those results should be described as independent laboratory results under the documented test conditions, not as additional NSF-certified claims. Selected independent test examples: Results vary by protocol, challenge concentration, water chemistry, flow conditions, and reporting limits. Review the full reports before comparing contaminant-specific performance. Substance Challenge Reported Result Calculated Reduction Chloramines 3.02 mg/L 96.69% Free chlorine 2.0 mg/L 95% Nitrate 42 mg/L 0.3 mg/L 99.29% Nitrite 3.8 mg/L 97.37% Fluoride 8.0 mg/L 1.96 mg/L 75.5% These examples are not presented as universal performance guarantees. Test conditions and reporting limits matter, and performance can vary as elements accumulate gallons and encounter different source-water conditions. Review the Phoenix Gravity Test Results See the available laboratory reports and contaminant-specific documentation before comparing performance claims. View Phoenix Test Results What Can Phoenix Gravity Filters Help Reduce? Independent laboratory testing has evaluated Phoenix Gravity New Millennium Edition™ Filter Elements across several drinking-water categories. Results differ by substance and test condition. Category Examples Evaluated Taste & odor concerns Chlorine and other compounds associated with taste or odor Chloramines Evaluated in separate independent laboratory testing PFAS compounds PFOA, PFOS, and other evaluated PFAS compounds Volatile organic compounds Selected industrial, solvent, and fuel-related compounds Heavy metals Selected metals evaluated in third-party laboratory reports Pharmaceutical residues Selected medications and related compounds evaluated in testing Disinfection byproducts Selected compounds associated with municipal water disinfection Sediment & particulates Rust, silt, sediment, cloudiness, and suspended material For broader educational information, visit our Drinking Water Contaminants Reference Guide. How Phoenix Gravity Filter Elements Work CTC-60 Coconut-Shell Activated Carbon Phoenix Gravity elements use premium CTC-60 coconut-shell activated-carbon-based media. Activated carbon contains an extensive network of microscopic pores that creates a large internal surface area for adsorption. Adsorption Selected chemical compounds are attracted to and retained on internal carbon surfaces. Activated carbon is especially useful for many compounds associated with taste, odor, chlorine-related concerns, and selected organic chemicals. Particulate Reduction The dense media structure also helps reduce suspended material such as rust, silt, sediment, cloudiness, and other particulates. Gravity-Fed Contact Time Water moves through the elements without electricity or household water pressure. Gravity-fed operation provides contact time between the water and filtration media as water moves into the lower chamber. Mineral Retention & TDS Phoenix Gravity elements are not designed for reverse osmosis or demineralization. Ordinary dissolved minerals such as calcium and magnesium generally remain, so a TDS meter may show little or no change after filtration. Compatible Berkey® Gravity-Fed Systems Phoenix Gravity New Millennium Edition™ Filter Elements are designed to fit compatible Berkey® gravity-fed systems, including: Go Berkey® Kit Travel Berkey® Water Filter Big Berkey® Water Filter Royal Berkey® Water Filter Imperial Berkey® Water Filter Crown Berkey™ Water Filter Berkey Light® Water Filter Compatibility is not the same as certification: Phoenix may physically fit additional Berkey® models, but the current system-level NSF listings specifically identify Travel Berkey®, Big Berkey®, and Royal Berkey® systems featuring Phoenix. The elements may also fit some gravity-fed systems from other manufacturers. For non-Berkey systems, compare element dimensions, stem configuration, mounting-hole size, and available chamber clearance before ordering. PF-2™ Compatibility & Fluoride Guidance Phoenix Gravity elements are compatible with Berkey PF-2™ Fluoride & Arsenic Reduction Elements. Install one PF-2™ for each compatible primary Phoenix element. 2 Phoenix Gravity elements → 2 PF-2™ Elements 4 Phoenix Gravity elements → 4 PF-2™ Elements Independent April 2026 testing reported a reduction in fluoride from 8.0 mg/L to 1.96 mg/L, equivalent to approximately 75.5% under that specific test condition. This result should not be interpreted as a sustained fluoride service-life rating. Customers specifically targeting ongoing fluoride reduction should consider compatible PF-2™ Elements and review the applicable PF-2™ testing and replacement guidance. PFAS Testing Independent third-party laboratory testing has evaluated Phoenix Gravity elements for their ability to reduce PFAS compounds, including PFOA and PFOS. PFAS is a broad class of chemicals, and reduction performance can vary significantly among compounds and with challenge concentration, water chemistry, flow, and total gallons processed. Customers concerned about PFAS should review the available Phoenix laboratory data alongside local water-quality information. For additional context, see our PFAS in Drinking Water Guide. TDS, Minerals, Hardness & Limescale Does Phoenix Gravity Lower TDS? No significant TDS reduction is normally expected because the elements are not designed to remove all dissolved minerals and salts. A TDS meter measures electrical conductivity associated with dissolved ions; it does not directly measure chlorine, PFAS, VOCs, pharmaceuticals, or many other compounds that may be addressed through adsorption. Does It Remove Beneficial Minerals? The elements are designed to retain ordinary naturally occurring dissolved minerals such as calcium and magnesium. Does It Soften Hard Water? No. Phoenix Gravity elements are not water softeners and are not designed to remove calcium and magnesium, which cause hardness and limescale. See our guide to what causes hard water and why most water filters do not remove it. Phoenix Gravity Filter Specifications Product Phoenix Gravity New Millennium Edition™ Filter Elements SKU PGF9-2 Quantity Set of 2 elements Primary media Premium CTC-60 coconut-shell activated-carbon-based media Designed capacity Approximately 2,750 gallons per element Designed pair capacity Approximately 5,500 gallons per set of 2 Maximum stated flow Up to approximately 4.2 gallons per hour per pair with a full upper chamber Element size Approximately 9.5 inches tall including stem × 2.5 inches diameter PF-2™ compatibility Yes Re-cleanable Yes, during useful filter life Warranty One-year limited warranty Electricity required No Plumbing required No Flow decreases as the water level in the upper chamber falls and can also vary with priming, source-water quality, sediment loading, element condition, and maintenance. Priming & Initial Installation Proper priming is important because activated-carbon media contain microscopic air pockets that must be displaced with water before normal flow can develop. Wash and dry your hands before handling the elements. Remove the elements from the packaging and inspect the element bodies, stems, washers, and hardware. Prime each element according to the current included instructions. Install the sealing washer in the specified position. Insert the threaded stem through the mounting hole in the upper chamber. Secure the element with the supplied hardware without overtightening. Install blocking plugs in any unused mounting holes. Perform the recommended assembly-verification test after installation. Improper priming can result in unusually slow flow. Improper installation can allow water to bypass the element through an opening or seal. Assembly Verification: Red Food Coloring Test The Red Food Coloring Test helps verify that the elements and blocking points are installed and sealed correctly. Remove PF-2™ Elements before performing the test. Use only the artificial red food coloring specified in the current product instructions. Add the specified amount to water in the upper chamber and allow the system to filter. If the lower-chamber water remains clear, the installed elements and seals have passed the assembly-verification check. If red or pink coloring appears below, inspect the element installation, seals, hardware, and unused openings, correct the issue, and repeat the test. The Red Food Coloring Test is an installation check. It does not measure reduction of every substance evaluated in laboratory testing. Cleaning & Maintenance Phoenix Gravity elements are designed to be re-cleanable during their useful service life. Remove the filter elements from the system. Use cool running water. Clean the exterior according to the current included maintenance instructions using the recommended method. Do not use soap, detergent, bleach, or household cleaners on the filtration media. Rinse thoroughly. Reprime if required. Reinstall with seals and hardware correctly seated. Repeat the assembly-verification test when appropriate. Cleaning can restore flow, not adsorption capacity. Removing surface buildup may improve flow, but cleaning does not reset the element's gallon guidance or restore adsorption sites that have already been used. What Can Affect Filter Life? The designed service life is approximately 2,750 gallons per element, but actual useful life can vary. Source-water quality Chlorine or chloramine concentration PFAS, VOC, or other adsorbable-compound concentration Sediment, rust, and turbidity Water hardness Daily water consumption Cleaning and maintenance Flow conditions Storage practices between uses Water with high sediment levels may require more frequent surface cleaning, while higher concentrations of adsorbable compounds can deplete carbon capacity more quickly. When Should Phoenix Gravity Filters Be Replaced? Replacement is appropriate when one or more of the following applies: The applicable designed gallon capacity has been reached Cleaning no longer restores acceptable flow The element body, base, or threaded stem is physically damaged The element has been exposed to inappropriate cleaning chemicals There is concern about contamination during storage or handling Tracking approximate household filtered water usage can make replacement planning easier, but source water conditions and actual use should also be considered. Softened Water & Salt Water Important: Manufacturer guidance warns against using salt water and indicates that salt-based softened water can prematurely clog compatible gravity-filter media and may affect applicable warranty coverage. If a salt-based softener is installed, review our softened-water FAQ before use. Why Buy Phoenix Gravity Filters From The Berkey? The Berkey has been an authorized Berkey® dealer since 2016. As replacement options evolve, our goal is to provide customers with clear information on compatibility, current availability, test documentation, and the differences between Black Berkey® and Phoenix Gravity elements. Authorized Berkey® dealer since 2016 Current compatibility guidance for Berkey® systems Direct access to Phoenix laboratory results Clear distinction between NSF-listed claims and separate independent testing Guidance for PF-2™, system compatibility, and replacement timing Frequently Asked Questions Are Phoenix Gravity filters a replacement for Black Berkey® Elements? They are a current compatible replacement option for Berkey® gravity-fed systems and are presently the primary replacement option available through normal authorized U.S. distribution. Phoenix and Black Berkey® Elements are not identical products; compare their media, capacity, testing, and certification information separately. Are Phoenix Gravity New Millennium Edition™ Filter Elements NSF certified? Current NSF listings identify the Travel Berkey®, Big Berkey®, and Royal Berkey® systems featuring Phoenix Gravity New Millennium Edition™ Filter Elements as meeting NSF/ANSI Standard 42 and NSF/ANSI/CAN Standard 372. Certification should be described by the listed system configuration rather than as a blanket claim covering every system in which a Phoenix element may physically fit. What NSF/ANSI Standard 42 claims are currently listed? The current listed claims for the applicable Travel, Big, and Royal Berkey® configurations featuring Phoenix include chlorine reduction and taste-and-odor reduction. Does NSF/ANSI/CAN Standard 372 mean Phoenix is certified for lead reduction? No. Standard 372 addresses lead-content/material requirements. Lead-reduction performance, where discussed, is supported by separate laboratory testing rather than Standard 372. Are all Phoenix contaminant claims NSF certified? No. NSF certification applies only to the specific standards, systems, and claims shown in the official listings. Other contaminant-reduction information comes from separate independent laboratory testing. Which Berkey® systems fit Phoenix Gravity elements? Phoenix Gravity elements are designed to fit compatible Berkey® gravity-fed systems including Go Berkey®, Travel Berkey®, Big Berkey®, Royal Berkey®, Imperial Berkey®, Crown Berkey™, and Berkey Light®. Physical compatibility does not mean every configuration carries the same certification. Will Phoenix filters fit another brand's gravity system? They may fit some similar gravity systems, but compatibility should be confirmed by comparing element dimensions, stem configuration, mounting-hole size, and available chamber clearance. How long do Phoenix Gravity filters last? Each element has a designed capacity of approximately 2,750 gallons, or approximately 5,500 gallons per set of two. Actual useful life can vary with source-water quality, contaminant concentrations, maintenance, and use. What is the Phoenix Gravity flow rate? A pair has a stated maximum flow of approximately 4.2 gallons per hour when the upper chamber is full. Flow declines as the water level falls and may also vary with priming, source-water conditions, sediment buildup, and element condition. Can Phoenix Gravity elements be cleaned? Yes. They are designed to be re-cleanable during their useful service life, in accordance with the current maintenance instructions. Cleaning may restore flow but does not reset gallon guidance or replenish used adsorption capacity. Do Phoenix Gravity filters reduce PFAS? Independent third-party laboratory testing has evaluated Phoenix Gravity elements for reduction of PFAS compounds including PFOA and PFOS. Results vary by compound and test conditions, so customers should review the applicable laboratory reports. Do Phoenix Gravity filters reduce fluoride? Independent testing has shown some fluoride reduction under a specific test condition, including a reported result of 8.0 mg/L to 1.96 mg/L, or approximately 75.5%. This should not be interpreted as a sustained fluoride service-life rating. PF-2™ Elements are the more appropriate supplemental option for customers specifically targeting ongoing fluoride reduction. Can Phoenix Gravity filters be used with PF-2™ Elements? Yes. Install one PF-2™ Element for each compatible Phoenix Gravity element in the system. Do Phoenix Gravity filters lower TDS? No significant TDS reduction is normally expected. Phoenix Gravity elements are not designed as reverse-osmosis or demineralization filters, and ordinary dissolved minerals generally remain. Do Phoenix Gravity filters remove beneficial minerals? They are designed to retain ordinary naturally occurring dissolved minerals such as calcium and magnesium. Do Phoenix Gravity filters soften hard water? No. They are not water softeners and are not designed to remove the calcium and magnesium responsible for hardness and limescale. Do Phoenix Gravity filters require electricity or plumbing? No. They operate in compatible gravity-fed systems without electricity, batteries, household water pressure, or a plumbing connection. Do Phoenix Gravity filters need to be primed? Yes. Proper priming helps displace trapped air from the media so water can flow through the element normally. Can I perform a Red Food Coloring Test? Yes. Follow the current included instructions and use only the specified artificial red food coloring. The test is an installation and sealing check, not a measurement of every contaminant-reduction claim. Can Phoenix filters be used with private well water? Private well-water chemistry varies substantially. Have the water periodically tested by an appropriate laboratory and select treatment based on the actual substances and conditions identified rather than assuming one filter addresses every possible well-water issue. Can Phoenix Gravity filters be used with salt-based softened water? Manufacturer guidance warns that salt-based softened water can prematurely clog compatible gravity-filter media and may affect applicable warranty coverage. Review the softened-water guidance before use. What warranty is included? Phoenix Gravity New Millennium Edition™ Filter Elements include a one-year limited warranty. Review the current warranty terms for conditions and exclusions. Can Phoenix Gravity filters be shipped to California or Iowa? No. Due to current state-specific regulatory requirements, the product is not available for sale to addresses in California or Iowa. Where can I review Phoenix Gravity test results? Visit our Phoenix Gravity Test Results page for available laboratory reports and contaminant-specific documentation. A Current Replacement Option for Berkey® Gravity Systems Phoenix Gravity New Millennium Edition™ Filter Elements provide Berkey® owners with a current replacement path, including clearly documented media, capacity, compatibility, independent testing, and specific NSF-listed system configurations.
