HydraPak 28 mm PNP inline-filter - hollevezel-waterfilter voor flessen en drinkbladders

Safe drinking water is the single most important thing you carry on any adventure, yet untreated streams and lakes can hide harmful bacteria and protozoa. The HydraPak 28 mm PNP Inline Filter turns suspect water into clean, drinkable hydration without waiting, pumping, or chemical aftertaste. Screw it onto any 28 mm threaded bottle or HydraPak reservoir, fill from a stream, and drink directly through the filter. The hollow fiber membrane removes 99.9999% of bacteria and 99.9% of protozoa, including E. coli, Giardia, and Cryptosporidium, while allowing a fast 1.5 L/min flow. Backflushable and built for the trail, it delivers up to 1,500 liters of filtered water in a compact, BPA-free package.

Who is it for

Backpackers, hikers, trail runners, and campers who need lightweight, on-the-go water treatment. It’s also ideal for international travel and emergency preparedness, where tap water may be unsafe. If you already use a HydraPak reservoir or a standard 28 mm bottle, this filter drops straight into your existing setup.

Tips

Before first use, rinse the filter by backflushing with clean water. After each trip, backflush until water runs clear, then allow to air dry. Do not allow the filter to freeze when wet, as ice can damage the hollow fibers. Replace after 1,500 liters or when flow rate becomes too slow even after backflushing.
