The water filtering system introduced by Bengt Brummer is designed for active users in different environments where the water quality cannot be considered as safe. Dubbed Pop Bottle, the dynamite shaped water bottle has the ability to collapse and expand as required.
To make it a full bottle, pull the knob downwards that will expand the lower half which will give it a parabolic shape full bottle. To enjoy the liquid, push the cap to the side and screw of the filter cap.
The inner construction comprises textile pre-filter, iodine bead to kill bacteria and active carbon that keeps the taste intact and filter out remaining parasites. That's why Pop Bottle can make th inside water 100% safe.
