Nordspur | Flowden Lightweight Survival Straw Water Filter

Prepare for your next outdoor excursion with this portable water filter straw.

Carrying enough water for a multi-day trek often adds heavy bulk to a rucksack, slowing down your pace. Relying on finding clean taps along remote trails is rarely a practical plan for outdoor hydration.

• Multi-stage internal filtration system
• Direct-sip trail hydration design
• Threaded base for bottle attachment
• Includes pouch and carrying accessories

Advanced four-stage filtration
The interior houses a multi-layer setup including a hollow fibre membrane. This system operates with a fine 0.01 micron rating to process natural water sources.

High-capacity processing
Each straw is constructed to filter up to 1500 L of water before requiring replacement. This 396-gallon volume serves well for extended camping trips or regular hiking seasons.

Best water filter straw for hiking adaptability
The base features a standard 28 mm diameter thread for easy connections. This allows you to attach the unit directly to common disposable or reusable drinks bottles.

Complete hydration kit
The filter arrives as a multi-piece setup including a separate water pouch. A carabiner and lanyard offer flexible attachment options for your rucksack or belt.
