This ultralight water purifier from GRAYL combines a water filter and bottle in a single solution that doesn’t require batteries or chemicals to operate.

Using your body weight and GRAYL’s ‘one-press’ process to quickly filter raw water through the system, this water filter produces 16oz (around 500ml) of clean and safe drinking water in around 15 seconds.

Simply fill your bottle at a stream or similar water source, and after 15 seconds you’ll have safe drinking water.

Each GRAYL bottle includes a replaceable purifier cartridge which will cover you around 40 gallons/150 liters of survival water filtration – this is likely to cover you for a period of up to 2-3 months.

The filters used by the GRAYL utilize a variety of purifying mediums including a positive ion ‘mesh’, non-woven ceramic fiber filter, and activated carbon in order to purify raw water, removing bacteria, protozoa, and chemicals as well as residual taste and odor.
