Water Purification Tablets

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.

• Treats water without any equipment
• Compact and light with a long shelf life
• Ideal backup to a filter or stove

Fifty compact tablets that make questionable water safe to drink when you can't boil or filter it. Each treats around a litre, so a single pack covers weeks of emergency use and weighs almost nothing in a grab bag. A cheap, long-life backup to keep alongside a proper filter, not instead of one.

• 50 tablets, roughly one litre treated per tablet
• Tiny and light for a grab bag or glovebox
• Long shelf life for a set-and-forget backup

A refillable bottle with a built-in filter that reduces chlorine taste and fine particles as you drink. It's aimed at everyday tap top-ups and day walks rather than treating dubious wild water, so pair it with purification tablets for genuine emergencies. A recognisable brand and an easy, low-effort way to keep drinking water palatable on the move.

• Filters as you sip, so no waiting or separate treatment step
• Cuts chlorine taste and fine sediment from tap and standpipe water
• Reusable filter discs are cheap and widely stocked in the UK

A leak-proof 2-litre reservoir with a bite-valve hose that fits inside most packs, so you drink steadily on the move.

• Carry 2L hands-free in your pack
• Bite-valve hose for sipping on the move
• Leak-proof seal keeps kit dry

A BPA-free 8-litre water carrier that folds flat when empty, so it takes up almost no room until you actually need to store or move water. Handy to keep in a cupboard for a supply interruption, or in the car for camping and days out. The carry handle and tap make pouring and hand-washing straightforward.

• Folds flat when empty to save storage space
• 8-litre capacity with a carry handle and tap
• BPA-free food-grade material

A rugged 18.5-litre jerrycan with a built-in ultrafiltration cartridge that removes viruses, bacteria and cysts as you pour. Fill it from a rain butt, stream or standpipe and it delivers clean drinking water for a household — up to 20,000 litres per cartridge, with no power or chemicals.

• Removes viruses, bacteria and cysts — not just chemicals
• Carries and stores 18.5L: days of water for a family
• Up to 20,000L per cartridge, no power or chemicals needed

LifeStraw's Peak Series straw is a rugged update to the classic personal filter: sip straight from a stream, puddle or water butt, or thread it onto a standard bottle or an inline hydration line. It removes bacteria, parasites and microplastics down to 0.2 microns with no batteries, chemicals or waiting. A sensible last-line backup to keep in a grab bag or the car for when the taps or your main filter let you down.

• Filters to 0.2 microns — removes bacteria, parasites and microplastics
• Threads onto standard bottles and inline hydration setups, not just direct sipping
• No batteries or chemicals — works cold, straight out of the packet

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.

• Drink straight from natural water sources with no setup
• No batteries or chemicals to run out
• Light and compact enough for any bug-out bag or car kit
