No. AquaZipo is designed for freshwater sources like lakes, rivers, and streams. It does not remove dissolved salts or chemicals found in seawater.

The filter will become difficult to draw water through as it reaches its capacity. Once the flow stops despite backwashing, it is time for a new AquaZipo.

This is the standard size for most plastic soda and water bottles. It allows you to screw the filter directly onto the bottle for a secure, leak-proof connection.

Our 0.01 micron membrane removes 99.9999% of bacteria and protozoa. While it removes most larger virus strains, for absolute viral protection in high-risk areas, we recommend additional treatment.

Yes. It works just like a standard drinking straw. It requires very little suction or squeezing pressure, making it safe and easy for the whole family.

Simply blow a few breaths of air back through the mouthpiece after drinking. This 'backwashing' clears out any sediment or particles trapped in the fibers.

Like all hollow-fiber filters, you should prevent it from freezing once used, as ice crystals can damage the membrane. Keep it in an inside pocket in sub-zero temps.
