1-year subscription of 4 COLDSTREAM FTO+ FILTERS

Replacement subscription: automatic delivery every 6 months / 1 year 

What's in the box

• 4 Coldstream FTO+ Filters
• 8 gaskets (comes with two washers per filter. Use one in the upper chamber between the filter and the steel. Keep the other in reserve)
• 4 wing nuts

Composition of ceramics

Material:Diatomaceous earth, a natural microporous mineral.

Manufacturing:

• Compression under high pressure, increasing the density and strength of the filter.
• Ultra-fine porosity of 0.1 microns, providing an effective barrier against bacteria, viruses and microplastics.

Advantages:

• Denser structure than conventional ceramics, guaranteeing finer and more durable filtration.
• In addition, the ceramic is enriched with ionized silver, abacteriostatic agentThat prevents the growth of microorganisms on the filter surface between uses, without chemical action on the filtered water.
• No loss of mechanical efficiency over time.

Composition of activated carbon

Material:High-quality mixed activated carbon, without animal components.

Manufacturing:

• Activation under high temperature, increasing the adsorption surface.
• Incorporated into the ceramic for stable chemical filtration over the life of the filter.

Advantages:

• Strong effective reduction PFAS *, pesticides, heavy metals and organic solvents.
• Reduction of fluorine and nitrates, a rare element in gravity filtration.
• Maintaining essential minerals in filtered water.
  * New PFAS tests expected in mid-2027

Manufacturing process

• High-pressure compressed ceramics: Ensures increased strength and uniform filtration.
• High-temperature activated carbon: Optimizes the adsorption of chemical contaminants.
• Laboratory tested to strict standards: ensures consistent filtration on1,500 liters or 6 months.

Coldstream FTO+ filters are manufactured in the UK and their components comply with the European REACH regulation (EC No. 1907/2006), ensuring the traceability and compliance of the substances used in their manufacture.

Information

• This filter does not require priming.
• Use at least 2 filters in your upper room.
• For faster filtration speed, use 4 filters in yourPure Filters Home 9 LOr yourPure Filters Family 12 L.We recommend this option for people whose need exceeds 10 liters of water per day (4 filters). 15 liters per day 6 filters.
• The rated capacity is 1500 liters using 2 filters, which is 6 months if you filter about 8 liters per day. We recommend having a replacement pair on hand. When installing them, mark in your calendar 6 months in advance to replace them.
• Preserves the mineral salts your body needs.
• Never use hot water on Coldstream FTO+ filters.
• Coldstream FTO+ filters are compatible with all sizes of water purifiers such as Berkey, Berkefeld, ProOne, weeplow (excluding the 5.6 Litre model), Purewell, Phoenix

The benefits of Coldstream FTO+ filters in the system Pure Filters By Gravity:

• Drinking water, free of bad taste and smell !
• Strong reduction of nitrates and fluoride thanks to the high-quality ingredients that Coldstream has chosen for its ceramics and activated carbon.
• Long-lasting bacteriostatic filter protection
• Does not require an additional filter for fluoride treatment in areas with high fluorine impact.
• Filters tap water, lake water, river, stream, puddle, rainwater but not salt water.
• 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.
• Can be installed in most gravity filtration systemsBerkey, Doulton/British Berkefeld, ProOne
• Made in the UK
• Tested by an independent laboratory certified to standards NSF/ANSI 42, 53 and P231.
• Coldstream has an NSF certification

Sustainability

We recommend replacing them every 6 months. Activated carbon, once the device is put into operation, has an effective duration of 6 months.

Coldstream FTO+ filters can be stored for several years without losing their filtration performance, as long as they have never been in contact with water.

Unlike some products whose properties degrade over time, a new Coldstream filter remains fully effective if stored in the right conditions.

Filter Replacement Frequency

Although Coldstream requires more frequent cartridge replacement (every 6 months), this offers the benefit of ensuring consistently effective filtration and water quality is maintained.

Our advice

For an average consumption of 8 liters per day, we advise you to install 2 Coldstream cartridges in your gravity water purifier and keep the other 2 as replacement cartridges. This way you ensure a year of autonomy in drinking and healthy water.

COLDSTREAM FTO+ Ceramic Gravity Water Filter Tests & Verifications:

The tests were conducted in accordance with NSF/ANSI Standards 42, 53 and P231 by IAPMO R&T (NJ), New Jersey USA, EPA ID #NJ01298 NJ DEP ID #03048 IAPMO ID #102, in compliance with all requirements set forth in the N.J.A.C. 7:9E and the N.J.A.C. 7:18.

Their laboratory is in compliance with all laboratory certification procedures and requirements, quality control set out in the N.J.A.C. 7:18; the NYCRR Subpart 55-2, the National Environmental Laboratory Accreditation Conference (NELAC) standards, and the ISO 17025 standard.

The filter was tested using a Coldstream system to NSF/ANSI Standards 42, 53, and P231 for the reduction of the listed substances. The concentration of substances in the water was reduced to a value less than or equal to the limit for the water leaving the system, as specified in NSF/ANSI Standards 42, 53, and P231.
