AquaZipo uses a medical-grade 0.01-micron hollow-fiber ultrafiltration membrane. Water passes through microscopic pores that physically trap bacteria (like E. coli and Salmonella), protozoan parasites (like Giardia and Cryptosporidium), microplastics, and sediment, allowing only clean, pure water molecules through without requiring chemicals or power.

You can filter freshwater sources including streams, rivers, creeks, lakes, ponds, and collected rainwater. AquaZipo is designed for freshwater and will not desalinate seawater or remove dissolved chemical contaminants or heavy industrial runoff.

Maintenance is simple. When the flow rate slows down, simply backflush the unit by pushing clean, filtered water backward through the mouthpiece using a syringe or clean squeeze bottle. This clears trapped particles from the hollow fibers and restores quick water flow.

Yes! AquaZipo features standard 28mm threading on its base, making it directly compatible with common store-bought disposable water bottles, collapsible squeeze pouches, and select hydration bladder setups. You can also use the included extension tube to drink directly from the source.

AquaZipo has an exceptional capacity of up to 4,000 liters (over 1,000 gallons) of filtered water when maintained with regular backflushing. Stored dry in a temperate environment, it features an emergency shelf life of up to 5 years, making it an essential addition to bug-out bags.
