The AquaZipo effectively filters freshwater from streams, rivers, lakes, rainwater, and tap water. It removes bacteria and parasites from any non-chemically polluted freshwater source. Avoid using with seawater or chemically contaminated water.

Reduced flow rate indicates the filter is reaching capacity. After filtering approximately 4000 liters or when suction becomes difficult, it's time to replace. Regular backflushing extends filter life significantly.

Avoid using in freezing conditions as ice can damage the hollow fibers. If the filter freezes, the membrane may crack and lose effectiveness. Store above 32°F and thaw completely before use.

Flow rate depends on suction strength and water clarity. Expect approximately 1 liter per 2-3 minutes with clean water. Murky water reduces flow but the filter still removes contaminants effectively.

The 0.01 micron filter removes bacteria and protozoa but not all viruses, which are smaller. For virus protection in developing countries, combine with purification tablets or use in areas with low viral contamination.

After each use, backflush with clean water to remove trapped particles. Store completely dry to prevent bacterial growth. The included dust cap protects the mouthpiece between adventures, maintaining hygiene.

Yes, the standard 28mm threading connects to most hydration bladders and water bottles. The included extension tube provides additional flexibility for various drinking systems and water collection methods.

Yes, though pre-filtering sediment improves performance. The AquaZipo handles turbid water but visible particles may clog the filter faster. Let sediment settle first or use a coffee filter for optimal longevity.
