Portable & Long Life-Span - This straw filtration at only 78.5'' long and 1.4" in diameter fits any 28mm threaded bottle, cup, or glass. It weighs just 2 ounces and fits in the palm of your hand, pocket, gym bag, backpack, survival pack or purse.

Smaller Pore Size - We all know that the smaller the pore size, the higher the filtering accuracy, our pore size is 0.1microns. Compared to the 0.2-micron water purifier straw on the market, 0.1 microns pore size water purifier straw maintains the optimum flow rate (16.9 fl oz/min / 500ml/min) and a high filtration accuracy at the same time.

High-Quality Materials & Versatile Filtering Modes - Made of durable food-grade plastics, manufactured with BPA-Free ABS, ensuring quality drinking water. Compared to the big filter straw on the market, water filters have a smaller frame, more convenient to use and more filtered modes, ideal for connecting with a soft water pouch or disposable water bottle, even as a replacement gravity filter to get water for family & group.
