  "short_description": "The ProOne Big II Water Filter 9.5L with Coldstream FTO PLUS or BOROUX filter elements is lightweight and ideal for the road. Always clean, drinkable water.",
  "description": "Whether you are on the go, preparing for emergencies or using it every day, the ProOne Big II Water Filter gives you clean drinking water wherever you are. It is easy to assemble and you need no electricity or plumbing. You can use water from almost any water source (including water from lakes, rivers, streams, ponds and rainwater), whether at home, in the office, at school, on the campsite or while travelling.\n\nThe ProOne Big II Water Filter has an exclusive design that lets you see how much water is in the lower container simply by looking at it. The ProOne Big II Water Filter is made of heavy-duty BPA-, BPS- and BPF-free plastic for a long service life and has a BPA-free plastic tap. It is supplied including a carry bag.\n\n#### Choice of 2 brands of filter elements for the ProOne Big II Water Filter 9.5L\n\nWith this water filter, choose one of the following brands of filter elements:\n\n**Coldstream FTO PLUS water filter elements**\n\nThe [Coldstream FTO PLUS water filter element](https://www.alternatievemiddelen.nl/producten/coldstream-fto-plus-waterfilter-element/) is NSF certified (NSF/ANSI 42) and has been tested by an [independent laboratory](https://forms.iapmo.org/rtws/listed_labs.asp?labid=0000102) according to NSF/ANSI standards 42, 53 and P231. See the [laboratory report](https://www.alternatievemiddelen.nl/wp-content/uploads/2025/03/Coldstream-FTO-PLUS-filterelementen_testrapport.pdf) for more details, and the website of [NSF](https://info.nsf.org/Certified/DWTU/Listings.asp?Company=C0091750&Standard=042). The Coldstream FTO PLUS filter elements have been proven to reduce/remove more than 200 contaminants, including fluoride, chlorine, chloramines, VOCs, bacteria, pharmaceuticals, lead, nitrate and heavy metals, while beneficial minerals and electrolytes remain in the water.\n\n**BOROUX Foundation™ Black filters**\n\nThe [BOROUX Foundation™ Black filters](https://www.alternatievemiddelen.nl/producten/boroux-foundation-black-filterelementen/) consist of, among other things, a special mix of activated carbon. The BOROUX Foundation™ Black filter elements contain silver, an antimicrobial agent, to prevent micro-organisms from affecting the product itself. These filters are not intended to filter micro-organisms.\n\nThey are also so powerful that they can remove red dyes from water without removing the beneficial minerals your body needs.\n\nThe BOROUX Foundation™ Black filters have 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](https://www.alternatievemiddelen.nl/ufaq/laboratorium-testresultaten-van-de-boroux-waterfilter/) for more details, with clarity and transparency coming first.\n\nBOROUX is NSF/ANSI/CAN certified by the Water Quality Association (WQA). This important achievement underlines their commitment to delivering safe, high-quality and effective water filtration solutions. This certification is not just a quality mark: it shows that their products meet the strict 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\n#### Features of the ProOne Big II Water Filter 9.5L:\n\n- The ideal water filter for on the go.
