It works on the principle of hollow fibers, so it traps anything larger than 0,1 microns. It meets EPA standards and removes up to 99,9% of bacteria and protozoa (including Giardia, Cryptosporidium). The filter is easy to clean; just pull it out of the bottle and rinse it in clean water. The stated lifespan of the water filter is up to **1000 liters**, and the secondary filter with activated carbon is **200 liters**, depending on water quality. The filter has a hard plastic neck with an integrated sturdy loop for easier carrying or attachment to your backpack. You can drink easily from the soft sports mouthpiece, and thanks to the durable sealing cap, you don’t have to worry about water spilling on your way.
