The original purifier that put Grayl on the map, this bottle is compact, fits in your backpack bottle pocket, and gives you clean, filtered and purified water anywhere in the world. It protects against pathogens, pesticides, chemicals, heavy metals, and microplastics and improves clarity, odour and taste. 

To use, simply fill, press, and drink. Pressing will take about 15 seconds (we tested it) and is easiest if you put the bottle on the ground and lean your body weight onto the lid, which has comfort pads on it for your hands. This forces the water through the cartridge. The cap will vent air while you do this.

The bottle is rated for about 300 cycles (150 L) and you'll know it's time to replace your cartridge when it takes 25 seconds to press your water. Replacement cartridges will last for 10 years in an airtight package if stored properly.
