The BOROUX Foundation Black filter cartridge fits most popular gravity-fed water filter systems, such as Berkey, British Berkefeld, ProOne, Phoenix Gravity, Aqua Logic, Monderma, Pure Filters and Newton, amongst others. The filter cartridge is designed for long-term use and features Stem Saver technology for added durability during use and cleaning.
This BOROUX filter reduces, amongst other things, more than 99% of chlorine, heavy metals, pharmaceutical contaminants (medicine residues), pesticides, herbicides, insecticides, plastic and industrial contaminants (PFAS), volatile organic compounds (VOCs), microplastics and disinfection by-products. The essential minerals that your body needs are retained in the process.
The advanced filter technology not only filters the water, but also transforms it. By removing more than 99% of harmful contaminants, the BOROUX Foundation Black filter ensures that your water is as pure and refreshing as nature intended. Every reduction in a contaminant contributes to an improvement in your health and wellbeing!
The filter consists, amongst other things, of a special blend of activated carbon. The BOROUX Foundation Black filter element contains silver, an antimicrobial agent, to prevent micro-organisms from damaging the product itself. This filter is not designed to filter out micro-organisms.
It is also so powerful that it can remove red colourings from water without stripping away the beneficial minerals your body needs.
The BOROUX Foundation Black filter has been tested by an independent laboratory (IAPMO R&T Lab NJ, ISO/IEC 17025) in accordance with NSF/ANSI standards 42, 53 and 401. See all test reports For further details; clarity and transparency are our top priorities.
BOROUX’s water filtration systems and filters are Gold Seal-certified by the Water Quality Association (WQA), the oldest independent certification body in the water filtration industry. Products must meet stringent testing requirements to be certified: industry standards (NSF/ANSI/CAN), annual audits of the production facility and compliance with the WQA’s certification schemes. Verification and validation through an independent testing process provide the assurance that consumers deserve.
They are certified for:
✔ NSF/ANSI 42: Appearance, taste, odour and nominal particle class I (view the certification)
✔ NSF/ANSI 372: Lead-free materials (view the certification)
✔ NSF/ANSI/CAN 401: Microplastics ranging in size from ≥ 0.5 µm to < 1 µm (view the certification)
These significant achievements underscore their commitment to providing safe, high-quality and effective water filtration solutions. This certification is not just any quality mark: it indicates that their products meet the stringent standards of NSF International (NSF) and the American National Standards Institute (ANSI), globally recognised organisations that safeguard public health and the safety of consumer products.
The BOROUX Foundation Black filter has been carefully designed to integrate seamlessly with most gravity-fed water filtration systems, including Berkey, British Berkefeld, ProOne, Phoenix Gravity, Aqua Logic, Monderma, Pure Filters, Newton and more. Whether you’re replacing filters in your existing system or embarking on a new journey in water wellbeing, these filters are designed for broad compatibility with gravity-fed water filtration systems.
A BOROUX water filter (BOROUX Legacy or BOROUX Legacy Compact) comes as standard with two original BOROUX Foundation Black filter cartridges. You can, if you wish, upgrade the BOROUX Legacy water filter to four filter cartridges.
You can select the elements order in sets of 2, but you can also order a replacement filter cartridge from us. This is particularly handy if only one filter cartridge in a water filter needs replacing (for example, if it’s damaged or lost) or if you want to replace the cartridge in, say, the Go Berkey (as this model only has one).

Preparing for use
The first step is to prime the filter element. It is important that this is done correctly, otherwise it will take a very long time to purify the water. For full details about BOROUX water filters, please refer to our library, which includes user guides, instructional videos and answers to frequently asked questions. If you’re unable to prime the system using the tap, then a automatic primer pump or manual primer pump order from us.
Scrub the BOROUX Foundation Black filter every 3–6 months. Gently scrub the surface of the filter for a few minutes using a scouring pad. Do NOT use soap or cleaning products on the filter. Re-prime the filters and reinstall them according to the instructions.
The BOROUX Foundation Black filter is designed for long-term use. However, the actual service life of the filter depends on various factors, such as:
● water quality;
● the contaminants present and their concentrations;
● daily water consumption;
● the substances you specifically want to filter out.
BOROUX provides a general replacement recommendation, based on a broad range of users and water qualities. In practice, the optimal replacement interval may vary from user to user.
Based on our experience with Dutch tap water, we recommend replacing the filter after, assuming average usage and the use of tap water, maximum three years. This is a practical guideline and not a fixed replacement period.
If you use water with higher concentrations of certain contaminants (for example, water from other sources), if your water consumption is high, or if you wish to ensure maximum protection against specific substances, it is advisable to replace the filters sooner.
If you want to determine exactly when replacement is needed, only regular analysis of the filtered water will provide a definitive answer.
Please note: Test results and maximum capacities vary depending on the type of contamination. Always refer to the most up-to-date information and BOROUX test results.
