PUT THE CONE INSIDE The Keystone Funnel

The Keystone Funnel is an original filter holder that connects two bottles together. The Folia Filters fit directly into the Keystone Funnel.



FOLD THE PAGE INTO a cone

Fold the filter in half, twice, and pop out one side; making a cone.



ATTACH THE KEYSTONE FUNNEL™ TO THE FULL (TOP) BOTTLE

Turn the empty bottle and Keystone Funnel over and screw the Keystone Funnel's lid onto the bottle of dirty water


 

 


ATTACH THE KEYSTONE FUNNEL™ TO THE EMPTY (BOTTOM) BOTTLE

Put on the Keystone Funnel's plastic cap, and screw the bottom (thinner end) of the Keystone Funnel onto a clean, empty bottle or onto a jerry can.



DO "THE FLIP"

Flip the whole system over to initiate gravity-based filtration. It will take around 15-20 minutes to filter 2 liters of water. When filtration is complete, remove the Keystone Funnel and drink safe water.
