- 1 × Outdoor Water Filter Straw
How fine is the filtration?
The 0.01 micron hollow fiber membrane removes 99.99% of bacteria and parasites from water.
How much water can it filter?
Each filter straw can purify up to 5000 liters of water before needing replacement.
Does it need batteries or chemicals?
No, it uses purely mechanical filtration — no chemicals, batteries, or electricity are required. Just sip and drink.
How much does it weigh?
It weighs only 64.9g and measures 14 × 3.7 cm, making it one of the lightest water purification options available.
Can I use it with any water source?
It works with freshwater sources like streams, rivers, and lakes. Do not use with saltwater, chemically contaminated, or heavily polluted water.
How do I know when to replace it?
Replace after approximately 5000 liters or when the flow rate significantly decreases despite back-flushing.
How do I maintain it?
Blow air back through the straw after each use to clear residual water. Air dry completely before storing and do not freeze with water inside.
Is this good for emergency kits?
Yes, its ultra-lightweight design and chemical-free operation make it ideal for survival kits, bug-out bags, and emergency preparedness.
