• Ultralight & Compact: The filter weighs just 2.2 oz (63 g) and packs small for easy access anywhere on or in your packing system.

• Build Your Own System: The I/O dual-thread design allows the filter cartridge to natively attach to the QuickDraw Reservoir, smartwater® bottles, the Platy Hoser, most Platy bottles and certain common 28mm PET soda/water bottles.

• Ultrafast Flow Rates: Hollow fiber cartridge filters up to 3L per minute with normal squeeze pressure.

• Easy, Effective Cleaning: Shake-to-clean or tool-free backflush methods make for quick and easy cleaning of the filter, so you can have fast filtration for your entire trip.

• Thoughtfully Rugged Design: Attached clean side cap flips open and creates a secure seal when closed, while the soft-touch filter housing is grippy even when wet and won’t pick up dirt from the ground.

• Hollow Fiber Advantage: Hundreds of tiny hollow fibers enable the microfilter to filter water faster than traditional filter media.

• Effective: Each microfilter is individually tested to ensure it meets all EPA & NSF guidelines for the removal of 99.9999% of bacteria and 99.9% of protozoa*.
