Personal Water Filter Straw: Survival & Camping

Ultralight Personal Water Filtration Straw

Pure Hydration. Anywhere. Anytime.

Never worry about your water source again. Whether you’re deep in the backcountry or prepping an emergency kit for your home, this palm-sized filter ensures you have access to clean, safe drinking water without the need for pumps, batteries, or chemicals.

Why Choose This Filter?

• Nano-Level Protection: Utilizes an advanced 0.02-micron hollow fiber membrane to remove 99.9999% of contaminants and micro-plastics.
• Featherlight Design: At just 30g (barely an ounce) and 4 inches long, it’s small enough to fit in a pocket or the smallest corner of your survival bag.
• High-Speed Flow: No more struggling to suck water through a straw. Our design allows for a 550ml/min flow rate, so you can hydrate instantly.
• Universal Compatibility: Features a standard 28mm thread that screws directly onto most common disposable water bottles.

How to Use & Install

• Direct Siphon: Place the bottom of the straw directly into a freshwater source (stream, lake, or glass) and drink.
• Bottle Attachment: Screw the filter onto a standard 28mm threaded plastic bottle. Squeeze the bottle to force water through the filter into a clean container, or drink directly from the straw.
• Extension Mode: Attach the included extension pipe to the bottom to reach water in tight spots or deep crevices.

Care & Maintenance

• Backwashing: After use, blow air through the mouthpiece to clear out excess water and debris.
• Storage: Always allow the filter to air dry completely before long-term storage to maintain the membrane's integrity.
• Lifespan: Replace your straw after 1,200 Liters (317 Gallons) of use to ensure maximum safety.
