Before first use, Remove the Ion Exchange Filter and rinse under clean tap water for 60 seconds. Reinstall the Ion Exchange Filter, reassemble your Filter to Cap, fill your bottle with water, screw the cap on, and allow a few seconds to pass while the filter is primed. After a few quick, strong sips, it should be easier to draw water and you can enjoy your new filter!
Note: Before using your LifeStraw® filter for the first time, make sure you have reviewed the instructions on the user manual and rinsed the product and filters.
