The Pure Filters Family 6 L is equipped with the following cartridges: Coldstream FTO+, selected for their performance and reliability.
A true reference in gravity filtration, this technology effectively eliminates bacteria, cysts, parasites, heavy metals, chemical and pharmaceutical residues, while greatly reducing the Nitrates and fluoride, without altering Essential minerals.
This top-of-the-range system incorporates a stainless steel tap for simple and direct access to quality filtered water.
With a capacity of 12 litres in the lower tank, it is ideal for families of 3 to 5 people, but also for use as a second home, motorhome or on your own. A reliable solution for drinking, cooking and enjoying healthier water every day.
What's in the box:
- 2 Coldstream FTO+ ceramic and activated carbon cartridges.
- 2 stainless steel tanks. The tall tub is designed with a reinforcement to make it easy to handle when you need to lift it.
- 1 stainless steel faucet.
- 1 lid and its lid knob.
- 1 rubber base.

The advantages of gravity water purifier Pure Filters Voyager (6 liters)
- Drinkable, healthy water free of bad tastes and smells !
- Ideal for a family of 1, easily transportable.
- Ideal for regions with high nitrate and fluorine concentrations: These filters are especially recommended for regions with high nitrate and fluorine presence, providing a reliable solution for these contamination problems.
- Strong nitrate reduction thanks to the high-quality ingredients that Coldstream has chosen for its ceramics and activated carbon.
- Maximum protection against bacteria, cysts and parasites by mechanical filtration at 0.2 μm / Virus: has been tested for Rotavirus removal with >99.99% removal at 3000L*
- Does not require an additional filter for fluoride treatment in areas with high fluorine impact (not compatible with Berkey PF-2s)
- Filter tap water, lake water, river, stream, puddle, rainwater but not salt water.
- Excellent protection against heavy metals.
- Does not require priming.
- Does not require energy to operate.
- Can be cleaned with an abrasive sponge and cold water.
- A lighter budget to ensure your autonomy in drinking and healthy water.
- Made in the UK.
- Tested by an independent laboratory certified to NSF/ANSI Standards 42, 53, and P231.
- Tested and validated to NSF standards and, as illustrated in Our technical data sheets, more contaminants are tested over a longer period of time.
Drinking water autonomy
With your system Pure Filters, you gain autonomy in everyday life and on the move. Gravity filtration equipped with Coldstream FTO+ cartridges provides microbiological reduction tested to NSF/ANSI P231 protocol and documented reduction of a broad spectrum of chemical contaminants to NSF/ANSI 42, 53, and 401, including heavy metals (lead, arsenic, mercury), PFAS, HAA5, pesticides, VOCs/SOCs, and some pharmaceutical residues. Whether hiking, camping or during a supply cut, you have a proven filtration solution when you comply with the conditions of use and hygiene described in the instructions. It's a practical and responsible answer to reduce your reliance on infrastructure, with measured and transparent performance.
Our tanks Pure Filters stainless steel
2-year warranty. Made of AISI 304 food-grade stainless steel, designed to guarantee quality and durability. Each tall bowl is equipped with a reinforcement for easy lifting, combining practicality and robustness. We placed several vats outside and subjected to the bad weather of the Luxembourg countryside during the autumn and winter. We have not noticed any corrosion. In addition, the steel is made of AISI304, specially designed for food use.
Our stainless steel tanks and accessories comply with the EU 1935/2004 framework and GMP (EU) 2023/2006 good practices. The metal migration tests according to the EDQM 2024 guide (metals & alloys) and the DIN 10955 sensory test are conclusive ('Pass') – SGS reports dated 08/10/2024. 304 composition validated according to FDA/GRAS/CBA standards; RoHS/Halogen/Nickel release EN 1811 compliance and REACH SVHC screening ≤0.1% – SMS reports 17/05/2024.

Do FTO+ filters reduce nitrates ?
Yes, FTO+ filters have the unique ability to reduce nitrates, which is rare for a gravity filtration system. Unlike other filters, even under pressure, which often require several specific cartridges to treat nitrates, FTO+ do so with a single cartridge model. This makes it a simple, convenient and effective solution for complete filtration, without additional accessories
Evidence
- Standards and Protocols: Testing to NSF/ANSI P231 (Microbiology), 42, 53, and 401 (Chemistry).
- Laboratory: tests carried out by accredited independent laboratories (IAPMO/ANAB), with dated reports.
- Volumes/Bearings: FTO+ tested up to 3,000 L per pair with intermediate control points (see PDS).
- Spectrum covered documented: PFAS (PFOA/PFOS...), chlorine/chloramines, VOC/VOC/SOC, heavy metals, nitrates/nitrites, HAA5/TTHM, pharmaceutical residues, microplastics, as well as bacteria, viruses and cysts within the framework of the P231 protocol.
Terms of Use
- Initial rinse: carry out the recommended rinsing cycles before first consumption; The flow stabilizes after this phase.
- Hygiene and re-contamination: regularly clean the low tank and the tap; Handle the filters with clean hands.
- Surface water: possible within the framework of protocol P231 and in accordance with the instructions (highly turbid water to be pre-filtered; avoid water suspected of industrial/chemical pollution).
- Temperature: use only cold/room temperature water; Do not use hot water.
- Replacement: For standard household use, replace the pair of Coldstream FTO+ approximately every 6 months.
Throughput and capacity
- Usable capacity: 6 L in the lower tank. To maintain a good flow rate, fill the high bowl when the low tank reaches about 1/4.
- Observed flow rate: variable depending on water level, temperature and filter condition; A slightly lower flow rate is normal at start-up and stabilizes after rinse cycles.
Materials & Compliance
- Tanks, lid and metal accessories made of 304 stainless steel food contact quality.
- Material contact compliance: EU framework 1935/2004 and GMP (EU) 2023/2006 good practices; successful metal migration tests according to the "Metals & Alloys" guide (Council of Europe); Odor/taste sensory test conforms.
