The Pure Filters Family 3.2 Gallons
Equipped with Coldstream FTO+ cartridges, selected for their performance and reliability.
This gravity system combines a high-density ceramic shell with an activated carbon core. It reduces bacteria, cysts and viruses (tested to NSF/ANSI P231), as well as heavy metals, chemical and pharmaceutical residues, nitrates and fluoride, while retaining essential minerals.
A stainless steel tap gives simple, direct access to filtered water. With a nominal 3.2-gallon (12 L) lower tank, it suits families of 3 to 5 people, a second home, a motorhome, or use on your own.
What's in the box
- 2 Coldstream FTO+ ceramic and activated carbon cartridges. (Can be equipped with 2 additional cartridges. Recommended for heavy water users)
- 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.
- 2 caps for high tank
The advantages of gravity water purifier Pure Filters Family (3.2 Gal)
- Water free of bad tastes and smells
- Easy to transport, no priming, no electricity needed
- Reduces bacteria and cysts by physical filtration through a high-density ceramic shell. Tested for rotavirus reduction: >99.99% at 3,000 L (see datasheet)
- Reduces nitrates and fluoride with a single cartridge model (figures in the datasheet, within the recommended replacement window)
- Documented reduction of heavy metals, including lead, arsenic and mercury
- Filters tap water. Surface water (lake, river, stream, rainwater) is possible under the conditions below. Not suitable for salt water
- Can be cleaned with an abrasive sponge and cold water
- Made in the UK
- Tested according to NSF/ANSI 42, 53 and P231 by an independent laboratory
About the ceramic and the silver
In addition, the ceramic is impregnated with ionic silver, a bacteriostatic agent that protects the filter itself by inhibiting the growth of micro-organisms on its surface between uses.
Drinking water autonomy
With your Pure Filters system, you gain autonomy in everyday life and on the move. Gravity filtration with Coldstream FTO+ cartridges provides microbiological reduction tested to NSF/ANSI P231, and documented reduction of a range of chemical contaminants tested to NSF/ANSI 42, 53 and 401, including heavy metals, chlorine and chloramines, HAA5, pesticides, VOCs/SOCs and some pharmaceutical residues. Whether hiking, camping or during a supply cut, you have a documented filtration solution when you follow the conditions of use and hygiene described in the instructions.
Our tanks Pure Filters stainless steel
Tanks and lid are made of food-grade AISI 304 stainless steel, with a 2-year warranty. The stainless steel sheet was tested by SGS (2024) for metal migration according to the Council of Europe/EDQM technical guide on metals and alloys, and for odor and taste (DIN 10955): no metals detected, odor and taste tests passed. Reports available on request.
Consult our FTO+ CF163W filter datasheet
Do FTO+ filters reduce nitrates and fluoride?
Within the recommended replacement window (6 months of standard household use), FTO+ cartridges reduce nitrates and fluoride. The datasheet gives the exact figures, with the test volume and the concentrations of the test water. If your water has a known high nitrate or fluoride level, check your own water analysis against those figures.
Evidence
- Protocols: NSF/ANSI P231 (microbiology); NSF/ANSI 42, 53 and 401 (chemistry)
- Laboratory: independent laboratory (IAPMO R&T), dated reports
- Volume: FTO+ tested up to 3,000 L (see datasheet)
- Documented contaminants: see the datasheet for the full list and the reduction figures
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 lower tank and the tap. Handle the filters with clean hands.
- Surface water: only under the conditions in the section below and in our Product Use and Water Quality Disclaimer.
- Temperature: use only cold or room-temperature water. Do not use hot water.
- Replacement: for standard household use, replace the pair of Coldstream FTO+ approximately every 6 months.
Flow and capacity
Nominal capacity: 3.2 gallons (12 L) in the lower tank. To keep a good flow rate, refill the upper tank when the lower tank reaches about a quarter. Flow varies with water level, temperature and filter condition, and is slightly lower at start-up before stabilizing.
Can surface water be filtered?
It can be, under conditions. FTO+ is tested to NSF/ANSI P231 for microbiological reduction (bacteria, viruses and cysts), but this does not make water of unknown origin safe from chemical pollution. Pre-filter highly turbid water, avoid water suspected of industrial, agricultural or chemical contamination, keep the lower tank and tap scrupulously clean, and follow the instructions for use.
