HydraPak 28mm Inline Filter Kit

Versatile Water Filtration for Backcountry Adventures

Best For: Hiking, backpacking, fastpacking and paddling when you need a versatile way to filter fresh water from compatible bottles, flasks and reservoirs.

Filter on the move. The HydraPak 28mm Inline Filter Kit makes it easy to filter fresh water without carrying a separate pump or bulky filtration system. Its 28 mm threaded connection fits compatible bottles and flasks, including HydraPak Stow bottles and 1 L Smartwater bottles.
