Chemical tablets that kill bacteria, viruses, and parasites in water. Lightweight backup to mechanical filtration.
Purification tablets are the ultimate backup water treatment. They weigh almost nothing, last for years, and can treat water even when your filter breaks or freezes. Unlike filters, tablets also kill viruses — making them essential for comprehensive water safety.
Chlorine dioxide is most effective and leaves least taste. Iodine works but has a stronger flavour.
Most tablets need 30 minutes for bacteria. Cryptosporidium may need 4 hours.
Unopened tablets last 4–5 years. Check expiry dates regularly.
Drinking before the treatment time is up means you’re drinking unsafe water.
Chemical reactions slow in cold water. Double the treatment time below 5°C.
Chlorine dioxide tablets that treat questionable water to make it safer to drink. A tiny, long-life backup for when filtering or boiling isn't possible.
A leak-proof 2-litre reservoir with a bite-valve hose that fits inside most packs, so you drink steadily on the move.
A pocket-sized straw filter that lets you drink directly from streams, rivers and lakes. No batteries, no chemicals and no moving parts — one of the simplest ways to make untreated water safe when the tap stops running.
An ultralight flexible bottle that rolls up flat when empty and holds two litres when full. A space-saving way to carry and store water in a grab bag.
A versatile squeeze filter you can use with its pouches, a water bottle or inline on a hydration pack. A refillable workhorse for treating larger volumes than a personal straw.
A large BPA-free water container with a built-in tap that stores and dispenses a family's emergency water supply, then packs away when empty.
An all-in-one filter bottle you fill from a tap, river or lake and drink straight from. The simplest option for everyday carry and travel.
