“After losing water for three days last year, and seeing stores sell out within hours, we didn’t want to be caught unprepared again. We now keep one LifeStraw in each car and a few at home. I hope we never need them, but knowing we can safely filter water if it happens again gives us real peace of mind.”

From Muddy, To Crystal Clear
When your usual water source isn’t available, LifeStraw offers power-free filtration for suitable freshwater. Its lab-tested hollow-fiber membrane has 0.01-micron pores that physically filter bacteria, parasites, microplastics, dirt, and silt without batteries or chemical treatment.
Compact enough to keep close. Ready for power cuts, camping, and travel.
When the Tap Stops Be Ready
A compact water filter for outages, evacuations, and the unexpected.
Keep it close. When your usual water supply is disrupted, filter the water from a any watersource using the LifeStraw.
Built for the Trail and for Emergencies
Keep it in your backpack, car, or emergency kit. Use the extended tube, attach it to a compatible 28 mm bottle, or pair it with the water storage bag.
The cleaning syringe helps keep the filter ready for your next use.
Why Always Have One in Backup?
“After our last outage, I realized we needed a way to filter water if the tap stopped working. I bought this, tested it at home, and now know where it is and how to use it.”
“It barely takes up any space in our emergency kit. I gave it a try when it arrived, so we’ll be ready to use it if we ever need to filter water.”
“I’m not a big prepper, but it makes sense to have a simple way to filter water if an outage affects the tap. It fits in a drawer, and I feel better knowing it’s there.”
“We had a brief outage one evening, and it reminded me to be ready if the water supply is affected. This filter is simple to use and easy to put away. I’m glad to have it on hand as a backup for drinking water.”
LifeStraw FAQs
Why do I need this when I can just boil water?
+
While boiling works, it's not practical in most emergency or outdoor scenarios. Boiling requires fuel, time (minimum 10 minutes), a heat source, and a container - resources you might not have when seconds count. In a wildfire evacuation or hurricane, you won't have time to set up a fire and wait. The LifeStraw provides instant, safe drinking water the moment you need it, with zero setup. Plus, boiling doesn't remove physical contaminants, heavy metals, or microplastics - our advanced filtration does.
How many should I buy for my family?
+
We recommend following the prepper principle "Two is one, one is none" - always have backup systems. For a family of four/five, we suggest:
- Minimum: 5 LifeStraws (one each)
- Recommended: 10 STRAWs (two per person) - ensures everyone can drink simultaneously if you encounter a water source, plus backup
What exactly does the 0.01 micron filtration remove?
+
Our 0.01 micron hollow fiber membrane removes:
- 99.999999% of bacteria (E. coli, Salmonella, Cholera, Typhoid, etc.)
- 99.999% of parasites (Giardia, Cryptosporidium, Amoebas)
- 99.999% of microplastics
- Dirt, sediment, and turbidity
- With our activated carbon stage: chlorine, bad taste/odors
Can my kids use it?
+
The LifeStraw requires moderate suction, so it's perfect for kids ages 5+. For younger children or toddlers, we recommend using the squeeze bag attachment to filter water directly into their bottles. This versatility is why we designed the system to work multiple ways.
Will it expire if I just keep it in my emergency kit?
+
Absolutely no shelf life or expiration date when stored dry. The LifeStraw can sit in your emergency bag, vehicle, or home for 10, 20, even 50 years and work perfectly the moment you need it. This is critical for emergency preparedness - you're not gambling on whether your filter will work when SHTF. Just store it in a cool, dry place and it's ready to save your life whenever disaster strikes. (Note: If you've used it, let it fully air dry before storage to prevent mold growth.)
I live in the city/suburbs - do I really need this?
+
Urban and suburban families are often at HIGHER risk. Why? You have zero alternative water sources and are 100% dependent on infrastructure that can fail instantly. Consider:
- Flint, Michigan water crisis - toxic lead for months
- Texas 2021 winter storm - millions without water for days
- Boil water advisories (2,000+ annually in the US alone)
- Hurricane Harvey - major city completely flooded
- Aging water infrastructure across America failing constantly
Rural folks have wells, streams, rainwater collection. City dwellers have...faucets that only work when the system works. When it fails, you're in the most dangerous position. The LifeStraw Emergency Water Filter Straw transforms you from helpless and dependent to self-sufficient in seconds.
How do I clean and maintain it?
+
- Every 25-50 gallons (or when flow rate slows), backflush the filter using the included syringe
- Fill syringe with clean filtered water, attach to outflow end, and forcefully flush backwards 3-5 times
- This reverses water flow and ejects trapped particles from the membrane
- That's it - flow rate restored to like-new
Between uses: Shake out excess water and air dry completely before storage to prevent mold. We include a protective cap to keep your mouthpiece sanitary.
What's your return policy?
+
We offer a 60-Day Risk-Free Trial and Lifetime Happiness Guarantee with our lifetime warranty. If you're not completely satisfied with the LifeStraw Emergency Water Filter Straw for any reason within 60 days, return it for a full refund - no questions asked.
Beyond that, we stand behind our product for life. If there's ever a manufacturing defect or issue with your LifeStraw Emergency Water Filter Straw, we'll replace it free of charge.
The only way you "lose" is by not having this when you need it.
