The BOROUX Foundation\u2122 Black filter element fits most popular gravity water filter systems, including Berkey, British Berkefeld, ProOne, Phoenix, Aqua Logic, Monderma, Pure Filters and Newton, among others. The filter element lasts for years and features Stem Saver technology for extra durability during use and cleaning.<\/p>\n

This BOROUX filters out over 99% of chlorine, heavy metals, pharmaceutical contaminants (drug residues), pesticides, herbicides, insecticides, plastic & industrial contaminants (PFAS), volatile organic compounds (VOCs), microplastics and disinfection contaminants, among others. The essential minerals your body needs are retained in the process.
\n <\/p>\n

Advanced filtration for healthier living<\/h4>\n

The advanced filter technology not only filters the water, it transforms it. By removing more than 99% of harmful contaminants, the BOROUX Foundation\u2122 Black filter ensures that your water is as pure and refreshing as nature intended. Every reduction of a contaminant contributes to improving your health and well-being!<\/p>\n

The filter includes a special blend of activated carbon. The BOROUX Foundation\u2122 Black filter element contains silver, an antimicrobial agent, to prevent micro-organisms from affecting the product itself. This filter is not intended to filter micro-organisms.
\nIn addition, it is so powerful that it can remove red dyes from water without removing the beneficial minerals your body needs.
\n <\/p>\n

Test reports and certification<\/h4>\n

The BOROUX Foundation\u2122 Black filter has been tested by an independent laboratory (IAPMO R&T Lab NJ, ISO\/IEC 17025) according to NSF\/ANSI standards 42, 53 and 401. See all test reports<\/a> for more details and in doing so, clarity and transparency are paramount.<\/p>\n

BOROUX is NSF\/ANSI\/CAN certified by the Water Quality Association (WQA). This significant achievement underlines their commitment to providing safe, high-quality and effective water filtration solutions. This certification is not just a seal of approval: it indicates that their products meet the rigorous standards of NSF International (NSF) and the American National Standards Institute (ANSI), globally recognised organisations that ensure the public health and safety of consumer products.
\n <\/p>\n

Compatible with other brands<\/h4>\n

The BOROUX Foundation\u2122 Black filter has been carefully designed to integrate seamlessly with most gravity water filtration systems, including Berkey, British Berkefeld, ProOne, Phoenix, Aqua Logic, Monderma, Pure Filters, Newton and more. Whether renewing filters in your existing system or starting a new journey in water wellness, the filters are designed for wide compatibility in gravity water filters.<\/p>\n

A BOROUX water filter (BOROUX Legacy\u2122 or BOROUX Legacy\u2122 Compact) comes standard with 2 original BOROUX Foundation\u2122 Black filter elements. You can optionally expand the BOROUX Legacy\u2122 water filter to 4 filter elements.
\nYou can use the elements order per 2<\/a>But with us, you can also order a separate filter element. Very handy if only one filter element in a water filter needs to be replaced (e.g. in case of damage or loss) or if you want to replace the element in, for instance, the Go Berkey (as it only has one).
\n <\/p>\n

The box of the BOROUX Foundation\u2122 Black filter element contains the following parts:<\/h4>\n

\u25cf 1x BOROUX Foundation\u2122 Black filter element
\n\u25cf 1x Black rubber ring<\/a>: for between the filter element and the stainless steel container
\n\u25cf 1x Wing nut<\/a>: for tightening the filter element
\n\u25cf 1x Priming Button<\/a>: brown rubber ring for priming the filter element with the tap
\n\u25cf 1x PrimeRite Universal Primer<\/a>: blue rubber tap attachment for priming the filter element
\n\u25cf 1x Bottle of red dye to do the red dye test
\n\u25cf 1x English-language manual (a Dutch-language manual can be downloaded in our library<\/a> and is also sent via e-mail after ordering)
\n 
\nPreparing for use<\/b><\/u>
\nThe first step is priming the filter element. It is important that this is done properly, otherwise purifying the water will take a very long time. For all information on BOROUX water filters, please refer to our library<\/a>, which includes manuals, instructional videos and answers to frequently asked questions. Should priming with the tap fail, a automatic primer pump<\/a> or manual primer pump<\/a> order from us.
\n <\/p>\n

Maintenance of the BOROUX Foundation\u2122 Black filter element<\/h4>\n

Scrub the BOROUX Foundation\u2122 Black filter every 3-6 months. Gently scrub the surface of the filter for a few minutes with an abrasive sponge. DO NOT use soap or detergents on the filter. Prime the filter again, install it and perform the red dye test to ensure correct installation of the filter.
\n <\/p>\n

When to replace?<\/h4>\n

The BOROUX Foundation\u2122 Black filter is designed to last for many years. However, we live in different times now than we did a few years ago. The number of contaminants has only increased and have become increasingly severe (think, for example, of PFAS or the hefty increase in medicine residues, pesticides, etc.). This has a huge effect on the filter, making it better to replace it a bit earlier. We therefore recommend replacing the BOROUX Foundation\u2122 Black filter every 3 years maximum when using tap water. If you use water from another source, we recommend replacing earlier.<\/p>","protected":false},"excerpt":{"rendered":"
