Operation
Method 1: Direct Filter Use
Place the straw directly into the water, immersing the
inlet mouthpiece into the water. Draw in and drink the
purified water from the outlet mouthpiece.
Method 2: Filter Extension
This method is best used when the water source is too
far out of reach for direct filter use. For straw extension,
connect the extension tube to the inlet mouthpiece,
making sure the tube is firmly and tightly attached.
Immerse the open end of the extension tube into the
water. Draw in and drink the purified water from the
outlet mouthpiece.
Method 3: Prefilter Application
This method is best used for more turbid water
containing organic and insect contaminants. For extra
filtration, attach the prefilter to the inlet mouthpiece
firmly. Then, place the straw directly into the water,
immersing the inlet end of the straw into the water.
Draw in and drink the purified water from the outlet
mouthpiece.
Method 4: Portable Water Bag
This method is ideal for portable transportation of the
water source. Collect water with the water bag, then
connect the bag to the straw from the inlet end. Place
your lips to the outlet mouthpiece and squeeze the water
bag to direct the water through the filter. Draw in and
drink the purified water from the outlet mouthpiece.
