The real risk
No power can mean no water.
The tap doesn’t always stop when the lights go out. Sometimes it’s worse: it keeps running, but it isn’t safe.
- On a well? The pump runs on electricity. No power, no water.
- Flood or broken main? The city says “boil your water.” With what stove?
- The bottled water at the store is gone by noon. One gallon weighs over 8 lb.
After Hurricane Helene in 2024, Asheville, NC was told to boil its tap water for weeks.
The backup
A water filter you drink through.
- Removes over 99.99% of waterborne bacteria and parasites*
- 0.1-micron hollow fiber: grit and microplastics stay in the straw*
- Up to 1,800 gallons per straw*. About 2 oz. No batteries, no pump.
- Honest: it’s not made for viruses, chemicals or salt water.
How it works
Sip from the source. Or screw it on a bottle.
No pump, no batteries, no tablets to wait for.
1Drink straight from the source
A creek, a rain barrel, a bucket. Pick the clearest water you can.
2Or screw it onto a bottle
It fits the 28mm thread of most water and soda bottles. Fill, screw, sip.
3Flush it, dry it, store it
Each straw comes with its own syringe: push clean water back through, let it dry, put it away.
Built for a blackout week
Not just a weekend hike.
Small, light, ready
Two ounces. Up to 1,800 gallons.
About 8 inches long and 2 oz: it fits in a kitchen drawer, a glovebox or a jacket pocket. No batteries to die, no cartridge to swap. The maker gives it no expiration date.
- Bacteria & parasites: over 99.99%*
- Grit & microplastics: down to 0.1 micron*
The math
1 gallon a day, per person
That’s the Ready.gov rule. One gallon weighs 8.3 lb, so you can’t carry much. One straw can filter up to 1,800 gallons*: about 5 years of 1 gallon a day for one person.
- Family of 4 = 4 straws
- Less with very muddy water
Two is one
One for the house. One for the car.
Storms don’t wait until you get home. Keep a straw in the glovebox, one in the go-bag and one per person in the kitchen drawer. That’s what the 4 and 6 packs are for.
Honest
What it does, and what it doesn’t
It removes over 99.99% of waterborne bacteria and parasites and stops grit and microplastics down to 0.1 micron*. It is not made for viruses, chemicals, heavy metals or salt water. Keep some bottled water too: the straw is your backup when it runs out.
Who is it for?
Perfect for…
- Storm seasonHurricanes, floods, ice storms.
- Campers & hikersDrink from the trail, carry less.
- Glovebox & go-bagIn case you get stuck.
- Every home kitNext to the flashlight.
- FamiliesOne straw per person.
- A smart giftFor a hiker, a new driver, a college kid.
Good to know: it’s a backup filter, not a cure-all. It isn’t made for viruses, chemicals or salt water. Keep bottled water too, and use the straw when it runs out.

- Verified buyerApril 5, 2025 · United States
Received these yesterday & gotta say, they're bigger than I had expected yet still small enough to stick in a backpack, day bag, fanny pack or wherever. Love the 1,800 gallon capacity/usage lifespan & that they include a syringe with each filter to back flow clean them, to help increase life span. Awesome product & will be buying more soon.
- Verified buyerDecember 26, 2023 · United States
These straws work excellent and are a reassuring item to always keep on hand. Water is so crucial to survival. I bought several to hand out to unprepared family and friends. I like that they are individually shrink wrapped making them easy to store and transport. I always keep one in not only my prep stuff but glovebox, brief case, suitcase etc. Great company too.
- JPB7mmAugust 7, 2024 · United States
I’m very pleased with the size and sturdy design of this product. Very easily stored in a backpack, UTV or a vehicle. I purchased the five (5) Survival Emergency Water Filters for family members as well as myself. At this time in our crazy world, one must be prepared for the unexpected!
- Verified buyerJuly 29, 2023 · United States
This is the best straw because it has a thread on the top where you can screw it on a standard bottle - saves on spillage - so efficient. I have bought some for my sister, my son and his family as well as ourselves!
- LanconleatherAugust 19, 2024 · United States
These are the perfect size for our “grab n go” bag we have ready for emergency. I macrame so I made nice holders for them to hang on the outside of the emergency kit. You never know when you may need to use and the size is convenient and light weight!
- Verified buyerApril 25, 2024 · United States
Purchased these for a big hiking trip. These were easy to carry, light weight, very sturdy, and great to use. I would recommend them to my friends and family that hike or do recreational outdoor stuff.
- SaraJune 5, 2024 · United States
So happy with these! Great for hiking or if you need water and you're on a hike or you're stuck somewhere and you're close to a river. These things are awesome. Highly recommend it
- Joseph BeyerJanuary 9, 2025 · United States
Going right in my bag. I love the fact you can back flush them and make them last longer and use them more. Great addition to any camping of survival kit
- Verified buyerSeptember 7, 2024 · United States
These are perfect for everyday carry. I keep one in my purse, bag, and vehicle. A must have as a survival or emergency when you have to drink unclean water.
- authorMichelleDutchOctober 31, 2025 · United States
Great product for emergency kits. Exactly as described. Lightweight and easy to use.
- Verified buyerJanuary 25, 2024 · United States
I keep one in my truck and several other places. Filters out the bacteria and junk in your water. Great to have just in case.
- Verified buyerNovember 17, 2024 · United States
Excellent product to have on hand in case of emergency. Hurricane Helene took out the power and water over a wide area. Having this tool allowed folks to still have drinkable water when city water stopped flowing.
- Rod FaulknerOctober 8, 2026 · United States
Having access to clean drinking water would be a critical priority in case of an emergency, especially if it requires you to evacuate your home. These emergency water straw filters are fantastic. They are portable, easy to use, and they work!
- MicahMarch 14, 2026 · United States
Using these for camping, I’ve used them before. These are actually really awesome. They work really well at cleaning and filtering the water and they last for the longest time ever. Definitely needed and you should always have some on hand.
- LOLAMay 16, 2024 · United States
This is a must in every household and emergency bin…I have mine in my storm shelter since I live in Tornado Alley
- ByrdsworldOctober 16, 2026 · United States
So glad that I have these in case of the situation where I will need clean drinking water and none is available such a convenient size also
- Verified buyerMay 1, 2025 · United States
Everyone should have one of these straws in their emergence kits. A must have if a disaster happens and your water supply is computerized and if you have no power to your system.
- Verified buyerAugust 23, 2022 · United States
Just knowing I have these water straws in my possession eases my mind!!!!! IF something was to happen with our water supply, 💧 I will be able to supply fresh clean water for my family and they don't expire!! You will have peace of mind knowing you would be able to survive a water contaminated issue or supply issue at that !! 😉
- Retired VetMomAugust 6, 2024 · United States
Was excited to get these in. Have had to use them in the past during emergency situations and they work great.
- Gary DarnellFebruary 5, 2025 · United States
Characteristics: Works great. A must have for any survival kit.

Good sturdy straws with easy to follow instructions. You can never have enough of these, for yourself and for gifting
- Ron.CSeptember 4, 2026 · United States
I have some larger ones but I wanted a few small ones so I can just stick one in my back pocket and off I go. A perfect size for this.
- I_AM_that_I_AM ♾May 2, 2025 · United States
I’m not gonna lie I was scared to use it, but I wanted to test it out just to make sure that it worked and I have to say it was not a disappointment. I’ll be taking this on my next camping trip and I’ll have one in the car for just in case the world hits the fan
