Unscrew the bottle and fill it with water from rivers, lakes, or taps.Pureflow is built to handle untreated water, even in outdoor conditions.

Close the bottle and drink directly through the nozzle.As you drink, water is pulled through the internal filtration system, no pumping, no waiting.

Inside the bottle, water passes through multiple filtration layers.The fiber membrane helps block bacteria, while the activated carbon improves taste and reduces odors.No chemicals. No electricity. Just physical filtration.

After drinking, unscrew the top and pour out any remaining water. This helps keep the filter clean and ready for the next use.

Blow through the nozzle to remove excess water from the filter.Let the bottle air-dry fully before storing it in your backpack or emergency kit.
