How To Use your Emergency Water Filter
Filtering your drinking water could not be simpler. You can drink directly from puddles or streams, or you may find it easier to scoop water with your wide-mouthed water bottle and drink from it using the device.
When new, the filter membrane is very dry and must be primed before use. Uncap the top and bottom caps and insert the base of the straw into the contaminated water, being careful to keep the mouthpiece dry. Let it sit for 30 seconds to allow water to creep up the membrane, then take 5 quick sucks to get the water flowing. It takes roughly 3-5 seconds of sucking to start the flow of water through the filter when the membrane is dry.
When finished drinking, blow a breath of air back down into the device to purge the remaining water out, shake, and recap. If you drink from murky water and the water flow stops, blow back into it to purge the water and mud from the filter. When you return home from a hiking trip, drink some tap water with the filter, purge the filter by blowing back into it, and leave it to dry with the caps off.
The water filter will not desalinate salt water, remove dissolved chemicals or minerals, nor remove viruses. If drinking from water which may have viruses in it (e.g. contaminated by human sewage), pre-treat with water treatment tablets. See the included instruction manual for more information.
