Boiling is useful for killing many microorganisms, but it isn’t always practical—especially when you’re away from home or dealing with an outage.

No electricity or fuel needed: PureFlow™ works without batteries, power, fire, or a stove. Just use it with a suitable freshwater source.

Ready when you need it: There’s no waiting for water to boil and cool before drinking.

Portable by design: Keep one in your emergency kit, backpack, vehicle, or travel gear without taking up much space.

Helps improve taste: The activated carbon filtration stage helps reduce unpleasant tastes and odors that boiling alone may leave behind.

PureFlow™ isn’t meant to replace every water-treatment method. It gives you a compact filtration option for situations where boiling may not be convenient.

PureFlow™ is designed around one simple idea: reliable filtration that’s easy to keep with you.

0.01-micron filtration: The hollow-fiber membrane is designed to help filter bacteria, parasites, microplastics, sediment, and other particles from suitable freshwater sources.

Multi-stage design: Multiple filtration layers work together rather than relying on a single filter medium.

Activated carbon: Helps improve taste and reduce unpleasant odors.

No batteries or electricity: There’s nothing to charge before you leave.

Compact and lightweight: Small enough for backpacks, emergency kits, vehicles, luggage, and camping gear.

Long-lasting: Designed to filter up to 1,800 gallons with proper use, cleaning, maintenance, and suitable source-water conditions.

Whether you're preparing for an emergency or heading outdoors, PureFlow™ gives you a filtration backup without adding bulky equipment to your gear.

PureFlow™ uses a multi-stage filtration system designed to help address common contaminants and impurities found in freshwater.

Hollow Fiber Membrane: Helps filter bacteria, parasites, microplastics, sediment, and fine particles.

Activated Carbon: Helps reduce unpleasant tastes, odors, and certain chlorine-related compounds.

PP Cotton Layer: Helps capture dirt, rust, sediment, and other suspended particles.

Protective Mesh: Adds another physical barrier while supporting consistent filtration and durability.

Important: PureFlow™ should be used only with appropriate freshwater sources. It is not designed to desalinate seawater or make every contaminated water source safe. Chemical, viral, heavy-metal, and other specific reduction claims should only be made where supported by testing for the exact PureFlow™ model.

PureFlow™ is designed for long-term preparedness rather than single use.

Filtration Capacity: Up to 1,800 gallons under appropriate conditions with proper use and maintenance.

Actual filter life can vary depending on the quality of the source water. Water containing large amounts of sediment or debris can reduce filter life and flow more quickly.

Storage: Keep PureFlow™ clean, dry, and stored according to the included care instructions when not in use.

Regular cleaning and proper storage will help maintain performance.

PureFlow™ is designed to be straightforward.

Remove the protective cap, place the intake end into a suitable freshwater source, and drink through the mouthpiece.

For best performance, avoid extremely muddy water whenever a clearer source is available. If necessary, allow heavy sediment to settle before filtering.

After use, follow the included cleaning and storage instructions before putting PureFlow™ away.

No batteries. No electricity. No complicated setup.

PureFlow™ is compact enough to keep wherever access to normal drinking water could become limited.

It's ideal for emergency preparedness, hiking and camping, road trips, travel, vehicle emergency kits, bug-out bags, fishing, hunting, and other outdoor activities.

The goal is simple: have a filtration option nearby before you actually need one.

That depends on how you're preparing.

For individual use, one PureFlow™ gives you a compact personal backup. For broader preparedness, keeping filters in multiple locations means you're less dependent on remembering to carry the same one everywhere.

A practical setup is:

1-Pack — Personal Backup

Keep one ready for yourself.

3-Pack — Preparedness Pack

One for home. One for the car. One for your bag.

5-Pack — Family Pack

A simple way to keep multiple household members and locations covered.

Rather than thinking about how many filters you need, think about where you'd want access to one if normal drinking water wasn't readily available.

No. PureFlow™ is not a desalination device and should not be used to make seawater drinkable.

It is designed for suitable freshwater sources. Always choose the cleanest available freshwater source whenever possible.

PureFlow™ requires no batteries, charging, or electricity, which is exactly why it works well as part of an emergency kit or outdoor setup.

Keep it stored properly and it's ready without having to remember to charge another device.
