BOROUX Foundation Black filter elements are compatible with most popular gravity-fed water filter systems, including Berkey, British Berkefeld, ProOne, Phoenix Gravity, Aqua Logic, Monderma, Pure Filters and Newton. The filter cartridges are designed for long-term use and feature Stem Saver technology for added durability during use and cleaning.<\/p>\n

These BOROUX filters reduce, 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 your body needs are retained in the process.
\n <\/p>\n

Advanced filtration for a healthier life<\/h4>\n

The advanced filter technology not only filters the water, but also transforms it. By removing more than 99% of harmful contaminants, BOROUX Foundation Black filters ensure 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!<\/p>\n

The filters consist, amongst other things, of a special blend of activated carbon. The BOROUX Foundation Black filter elements contain silver, an antimicrobial agent, to prevent micro-organisms from damaging the product itself. These filters are not designed to filter out micro-organisms.
\nThey are also so powerful that they can remove red colourings from water without stripping away the beneficial minerals your body needs.
\n <\/p>\n

Test reports and certification<\/h4>\n

The BOROUX Foundation Black filters have 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<\/a> For further details; clarity and transparency are our top priorities.<\/p>\n

BOROUX\u2019s 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\u2019s certification schemes. Verification and validation through an independent testing process provide the assurance that consumers deserve.<\/p>\n

They are certified for:
\n\u2714 NSF\/ANSI 42: Appearance, taste, odour and nominal particle class I (view the certification<\/a>)
\n\u2714 NSF\/ANSI 372: Lead-free materials (view the certification<\/a>)
\n\u2714 NSF\/ANSI\/CAN 401: Microplastics ranging in size from \u2265 0.5 \u00b5m to < 1 \u00b5m (view the certification<\/a>)<\/p>\n

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.
\n <\/p>\n

Compatible with other brands<\/h4>\n

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\u2019re 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.<\/p>\n

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.

The box of BOROUX Foundation Black filter elements contains the following items:<\/h4>\n

\u25cf 2x BOROUX Foundation Black filter elements
\n\u25cf 2x Black rubber rings<\/a>: to be fitted between the filter element and the stainless steel housing
\n\u25cf 2x Wing nuts<\/a>: to tighten the filter element
\n\u25cf 1x Priming Button<\/a>: a small brown rubber ring to prime the filter elements with the tap
\n\u25cf 1x PrimeRite Universal Primer<\/a>: blue rubber attachment for the tap to prime the filter elements
\n\u25cf 1x English-language user manual (a Dutch-language user manual is available for download at our library<\/a> and is also sent by email after the order has been placed)<\/p>\n

Preparing for use<\/b><\/u>
\nThe first step is to prime the filter elements. 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<\/a>, which includes user guides, instructional videos and answers to frequently asked questions. If you\u2019re unable to prime the system using the tap, then a automatic primer pump<\/a> or manual primer pump<\/a> order from us.
\n <\/p>\n

Maintenance of the BOROUX Foundation Black filter elements<\/h4>\n

Scrub the BOROUX Foundation Black filters every 3\u20136 months. Gently scrub the surface of the filters for a few minutes using a scouring pad. Do NOT use soap or cleaning products on the filters. Re-prime the filters and reinstall them in accordance with the instructions.
\n <\/p>\n

Service life of the BOROUX Foundation Black filters<\/h4>\n

The BOROUX Foundation Black filters are designed for long-term use. However, the actual service life of the filters depends on various factors, such as:
\n\u25cf water quality;
\n\u25cf the contaminants present and their concentrations;
\n\u25cf daily water consumption;
\n\u25cf the substances you specifically want to filter out.<\/p>\n

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.<\/p>\n

Based on our experience with Dutch tap water, we recommend replacing the filters after, assuming average usage and the use of tap water, maximum<\/b> three years. This is a practical guideline and not a fixed replacement period.<\/p>\n

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.<\/p>\n

If you want to determine exactly when replacement is needed, only regular analysis of the filtered water will provide a definitive answer.<\/p>\n

Please note:<\/b> 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<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"
