Graphene:Ultra

Graphene:Ultra Portable Water Purification

Extra protection when you need it most

For the first time you can now benefit from state-of-the-art filtration technology while out and about, with Lifesaver's new, exclusive Graphene:Ultra water purifiers. Designed to reduce or remove PFAS/PFOA (forever chemicals), heavy metals, antibiotics and chemical contamination to leave nothing but safe, clean, great-tasting drinking water - wherever you are.

No need to replace your existing LifeSaver Jerrycan

Developed after eight years of extensive R&D, LifeSaver's new Graphene:Ultra Filter Cartridge is exactly the same size and shape as our standard ultrafiltration cartridges, so can be retrofitted to all existing LifeSaver Jerrycans. Or you can choose a new LifeSaver Graphene:Ultra Jerrycan or one of our money-saving packs with a Graphene:Ultra Filter Cartridge already installed.

What difference does Graphene make?

Our filter cartridges already remove 99.99% microbiological contaminants and sediment; the addition of Graphene enables them to remove or reduce chemical contaminants from your water. These include:

  • PFAS/PFOA - forever chemicals
  • Heavy metals
  • Antibiotics and pharmaceuticals

When will I need a Graphene:Ultra water purifier?

If you live or are travelling in the UK, unless you have a particular concern about the extra contaminants the graphene removes, you probably won't need one. However, there are parts of the world where the groundwater is heavily contaminated naturally - or from mining and industrial activity; places where the local legislation isn't yet able to monitor or control what is released into the groundwater system.

If you are travelling through - or working in - one of those places, then you could benefit from the additional protection graphene technology will offer. Check before you travel and take a Graphene:Ultra Filter Cartridge with you and swap it out when you need it. 

How does it work?

Providing a whole new level of filtration, the new graphene-enhanced filter features our existing ultrafiltration membrane - with an average pore size of just 15 nanometres - and an additional Graphene composite element, to add three new chemical adsorption mechanisms:

  • Conjugated molecules stacking
  • Electrostatic interaction and surface complexation
  • Hydrophobic interactions

How much water does a Graphene:Ultra Cartridge Filter?

It's important to note that, unlike the Ultrafiltration Membrane, these new filtration mechanisms don't prevent water flow when they've reached their limit; they simply stop removing contaminants. The UF element will continue to remove microbiological content until the FailSafe kicks in but, if you are having to source water in a particularly toxic environment, you'll need to keep track of how much water you've filtered, and replace the cartridge when necessary.

The Graphene:Ultra Filter Cartridge removes or reduces:

 Contamination

Effectiveness

Capacity
Bacteria Removes 99.9999% Up to 20,000 litres*
Viruses Removes 99.99% Up to 20,000 litres*
Parasites Removes 99.99% Up to 20,000 litres*
Microplastics Removes 99.99% Up to 20,000 litres*
PFAS/PFOA Reduces to safe levels Up to 1,000 litres
Lead Reduces to safe levels Up to 1,000 litres
Vanadium Reduces by over 30% Up to 700 litres
Copper Reduces by over 30% Up to 700 litres
Chromium Reduces by over 30% Up to 700 litres
Antibiotics Removes 99.9999% Up to 1,200 litres
Sediment/particulates Removes 99.99% Up to 20,000 litres

The amount of water the Graphene:Ultra cartridge will purify depends on the level of contaminant, so our figures show worst-case scenario. For example, our tests indicate that the filter is effective at removing PFAS/PFAO for up to 1000 litres; in reality, if the PFAS contamination is low, the filter will work for longer. However, unless you have access to accurate information about the level of contaminant present, the safest option is to work with the volumes we have provided.

Has the new Graphene technology been tested?

So far our new filters have been independently tested and proven to meet NSF/ANSI 42 – 2022 Version: Drinking Water Treatment Units, Aesthetic Effects, Section 4 – Material Safety, NSF/ANSI/CAN 372 – 2020 Version: Drinking Water System Components – Lead Content and NSF P231 – 2003 version: Microbiological Water Purifiers for Virus, Bacteria and Cyst. However we are still running tests to see exactly what and how much the filters will remove and for how long.

How does a Graphene Filter work?

Unlike the ultrafiltration membrane, that behaves like a sieve, the graphene element acts more like a carbon filter – like a sponge. Once a sieve’s holes are blocked, water stops passing through; once a sponge is saturated, water simply passes through. This means the graphene element can’t offer a FailSafe mechanism; once it’s removed everything it can, chemical contaminants will start to pass through the membrane to the drinking water.
