2.PORTABLE: This straw filtration at only 6.7” long and 1.1” in diameter fits any bottle, cup, or glass. It weighs just 5 ounces and fits in the palm of your hand,pocket, gym Bag, backpacks, survival packs and Purses. You can take it anywhere you want conviniently.

3.OPTIMUM PORE SIZE: Our pore size is 0.1 micron. We all know that the smaller pore size, the higher the filtering accuracy, but the lower flow rate. Also we know that a 0.2 micron aperture is enough to filter out 99.99999% of the tiny material. Compared to the 0.1 micron filter straw on the market, our 0.1 μm pore size filter straw maintains the optimum flow rate while maintaining the same filtration accuracy.

4.VARIOUS APPLICATION: Mini and lightweight filtering system is ideal for recreation, hiking, camping, scouting, domestic and international travel, and emergency preparedness.

DIRECTIONS: use the filter just like a straw. The first sucked water should be spat out. Please shake out excess water after use. Snap both end caps closed. Store in a cool, dry place.
