Outdoor water filtration designed to strip bacteria, parasites and heavy metals for safer drinking on the move. Lightweight, bottle-compatible construction makes packing easier for campers, backpackers and emergency kits. Is the Purewell Outdoor Water Filter the survival tool worth carrying on every trip?
⚡ At a Glance
- • Filtration Accuracy: 0.01-micron hollow-fibre membrane blocks bacteria, parasites and microplastics while reducing odours and residual chlorine
- • Best for: Backpackers, campers and emergency-preparedness kits needing lightweight, bottle-compatible purification
- • Not ideal for: Users seeking TDS reduction or large-scale household water treatment
Five-stage filtration combines hollow-fibre ultrafiltration with activated carbon and medical-grade PP cotton. Lightweight, certified construction supports fast flow and broad outdoor compatibility.
Fast hydration on the go – with a 0.01-micron hollow-fibre membrane
Hollow-fibre ultrafiltration uses microscopic pores to physically trap bacteria and parasites while allowing water to pass; the design sustains a flow rate around 550 mL/min. The membrane is paired with mesh plugs to maintain steady throughput during use.
Quick sipping from streams or bottles during short breaks keeps energy levels up without lengthy filtering pauses.
Cleaner taste while keeping minerals – thanks to coconut shell activated carbon and no TDS reduction
Coconut shell activated carbon adsorbs odours, residual chlorine and many organic compounds, while the filtration chain does not lower TDS values, so dissolved minerals remain in the water.
Water tastes fresher and retains beneficial minerals, helping maintain balanced hydration on multi-day trips.
Built for outdoor use and reliability – with food-grade materials and independent certification
BPA-free food-grade plastic, double-layer medical-grade PP cotton and robust connection modes make the unit durable and lightweight (under 100 grams). Performance has been tested and approved by SGS and TÜV (Report No. ASH15-005515-01).
Easy to attach, pack and trust in emergencies, offering confidence for wilderness adventures and survival kits.
