Pristine Water Purification Drops
Pristine positions itself as a best-in-class drop formulation for campers who prioritize taste and fast, convenient dosing; its liquid chemistry minimizes the chlorine/iodine aftertaste common to many tablet options and allows precise portioning for small group use. Compared with tablet systems on this list, Pristine’s bulk-drop format often yields a lower cost per treated litre for frequent users and eliminates the need to crush or dissolve pills, though it requires careful measurement in cold conditions.

Potable Aqua Chlorine Dioxide Water Purification Tablets
Potable Aqua’s chlorine dioxide tablets are marketed as a market-leading choice for campsite use because chlorine dioxide has broad-spectrum activity — including better performance against protozoa like Giardia and Cryptosporidium — and works reliably in cold or murky water. Financially they sit above basic iodine tablets on price, but their faster contact times and reduced taste issues make them a technically superior option for campers who need compact, high-efficacy treatment in challenging conditions.

Aquatabs Water Purification Tablets
Aquatabs are widely used by aid organizations and campers alike for their low cost, long shelf life, and consistent performance using stable free-chlorine chemistry (NaDCC), making them a budget-friendly baseline option for chemical treatment while camping. They compare favorably on price per litre to liquid drops, but are generally slower or less effective than chlorine dioxide products against certain protozoa, so campers choose Aquatabs when affordability and availability are the primary concerns.

Coghlan's Drinking Water Germicidal Tablets
Coghlan’s germicidal tablets are a pragmatic, entry-level choice for campers who need ultra-lightweight, inexpensive emergency treatment — they are typically iodine-based and widely available at low cost. Compared with the chlorine dioxide and NaDCC options on this list, Coghlan’s tablets sacrifice some spectrum of activity and can impart a stronger taste, but their near-universal availability and minimal upfront cost make them a sensible backup for short trips or emergency use.
