Key Features

• 【5-Stage Filtration】：The Survimate water filter bottle adopts a composite filter technology, can reduce most contaminants. The filter element uses a coarse filter screen, a 0.01μm hollow fiber UF membrane, a sediment PP membrane, purification beads, and an activated carbon fiber to reduce chlorine, bad odor and intercept heavy metals, sediment, soil, organic matter and other impurities, etc.
• 【Smaller Filter Pore Size】：The filter pore size of the hollow fiber UF membrane is 0.01 microns so that it can filter out 99.99% harmful materials from the water while other brands' filter pore size is only 0.2 microns. The smaller filter pore size, the higher filtering accuracy.
• 【Ultimate Wilderness Survival Assistant】：This versatile water bottle not only helps providing healthy, drinkable water in harsh outdoor conditions, but will help you to find direction using the built-in compass on the top.
• 【Instant Fresh Water】：Just fill up the bottle and drink. Nothing could be simpler - no pumps or hoses, no squeezing, no batteries or bulbs! Only sip 5 to 8 times to get clean water.
• 【Long Lifespan & Replaceable 】：No need to worry about replacing filters for up to 1500L/year of continuous usage. Replaceable filters save you money as the water bottles themselves have a very long life. (According to different water quality, the lifespan of the filter would be a little different.)
