I bought these after our boil notice last winter. We had four days of it and I felt helpless. I got the Family Pack, one for each of us and one for the truck. First sip takes a hard pull until it's wet, then it's fine.
I was worried I wouldn't have the lung power. It takes a minute but I can do it. The squeeze pouch would be easier, wish I'd bought that one.
I had 6 cases in the garage and they take up a whole wall. This doesn't replace all of it but it's what I'd grab.

Why the Tap Stops
The tap doesn't need a war to stop. It needs a main break, an ice storm or a dead pump.
On a well, the pump runs on electricity. No power means no water, even though the pipes are fine.
On city water, the water can keep running and still not be safe to drink. That's what a boil notice means.
- Asheville, NC: a 53-day water crisis after Helene, until the boil notice lifted in November 2024 (WUNC).
- Jackson, MS: more than seven weeks under a boil-water notice in 2022 (Fox Weather).
- Texas, 2021: more than 14 million people affected by boil water notices at one point (Fox 5).
How It Works
Water passes through four stages. Nothing to charge. Nothing to plug in.
- Coarse screen. Catches sand, mud and debris.
- Cotton layer. Catches fine silt.
- Flow layer. Evens out the pressure so the draw stays steady.
- Hollow-fiber membrane, 0.01 micron. Blocks 99.99% of bacteria and protozoa.
Before the first drink: draw water through 3 to 5 times to prime it. The first few sips take the most effort. That's normal.
Two ways to use it: sip straight from the water, or squeeze. The threaded cap fits most standard water bottles, so you screw it on and squeeze. That means no pulling, and you can fill a glass or a pot.
What It Removes, and What It Doesn't
It removes 99.99% of bacteria and protozoa. That includes E. coli, Salmonella, Cholera, Giardia, Cryptosporidium and Legionella. You can't see these germs in a glass. The 0.01 micron membrane also blocks microplastics.
It doesn't remove viruses, chemicals, heavy metals or salt. Boil or add tablets when viruses are a concern. Don't drink water you suspect is chemically contaminated.
CDC says filters at 0.3 micron or smaller remove bacteria and parasites. This one is 0.01 micron. CDC also says boiling or disinfecting can't make chemically contaminated water safe.
Storage and Care
It has no expiration date when stored dry. Keep it from freezing, and let it dry before you put it away.
It's rated for 1,800 gallons, which is years of clean water from a single straw. So you buy it once: one per person, plus one for the go-bag. That's a big part of why the pack makes sense.
An unused, dry straw can live in a drawer or glovebox. A used one has to come in from the cold. If you think a used one froze, replace it.
How It's Tested and Stored
Tested. Third-party lab tested for bacteria and protozoa removal. Pressure-tested for membrane integrity, seal strength and leak resistance. It's tested to the rated figures, and it's been drop-tested from about 3 feet. In lab testing, about 210,000 E. coli per milliliter went in, and none were detected coming out.
Built. The materials are BPA-free and FDA food-contact-compliant. Hospital-grade purification and military field systems use the same type of hollow-fiber technology.
Stored. It has no expiration date when stored dry. You can store it 5, 10, even 20 years. Keep it from freezing, and let it dry before you put it away.
Shipping
Standard shipping is $4.95 and Express is $9.95. Delivery times are on our Shipping and Returns page. Every order ships the next business day, tracked and insured.
Neither one beats a storm that's already on the forecast. That's the reason to order before you need it.
What's in the Box
One filter straw per unit. It's 2 oz, about 8 inches long and BPA-free. No batteries, no pump and no moving parts.
There's no pouch, hose or syringe in this box. Those come with the Emergency Water Filter System.

Your water is a countdown
CDC says to store at least 1 gallon per person per day for 3 days, and 2 weeks if you can. A family of four goes through about a case of bottled water a day. Two weeks is about 19 cases, and the aisle empties first. One person's two weeks of water weighs about 117 lb. One straw weighs 2 oz. In July 2026 the FBI and EPA warned of cyberattacks on water utilities in at least seven states. CISA said boil water notices followed, while officials say drinking water was largely unaffected. Your town's notice won't come with a date. You can still choose what's in the drawer before it comes.
2 ounces. 1,800 gallons.
Four stages, in order
Screen, cotton and flow layer take the grit first, so the 0.01 micron membrane does the fine work. Nothing to charge, nothing to break down.
What it does, in plain numbers
Rated 1,800 gallons. Removes 99.99% of bacteria and protozoa. Tested to the rated figures.
One per person
Sharing one mouthpiece is fine for a day. Not for two weeks. So plan one per person, plus one each for the bag, the car and the home.
Kept where you already are
At 2 oz and about 8 inches, an unused straw fits a kitchen drawer, a purse or a glovebox. It waits there, dry, with no expiration date.
One per person. Plus one for the go-bag.
Not every straw is built the same
The first two weeks without water
The tap coughs
Picture a Tuesday in January. A main breaks across town, or the power takes out your well pump. You figure it'll be back by dinner.
The aisle goes first
The word gets around. The store's water aisle is thin by evening and bare soon after.
You start counting
One gallon per person per day is CDC's figure. Four people, four gallons. Cooking and washing up aren't in that number.
The notice goes up
Water's back, but the notice says boil it first. That takes a working stove and fuel, and the pots never stop.
The bottles run low
This is when a straw earns its drawer space. Everyone has their own, and you fill from whatever water you can find.
You still have water
Asheville's notice ran 53 days. Jackson's ran more than seven weeks. A plan has to last longer than a case of water.
Stored water runs out. A filter keeps going.
What buyers say
My daughter thinks I worry too much. Maybe so. But it's a small thing in a drawer and I sleep better knowing it's there.
I'm no prepper. I just did the math on how much water I could actually store in this house. It wasn't much. This made more sense.
Sent one to each of my kids. Nobody rolled their eyes, which surprised me. My son put his right in the glovebox.
Tried it on creek water at the lake house. It takes some suction but the water came through clear and tasted fine.

Questions people ask
How do I know it really works?
It has a 0.01 micron hollow-fiber membrane that removes 99.99% of bacteria and protozoa, including E. coli, Giardia and Cryptosporidium. It's tested to the rated figures. Buyers give it 4.8 stars across 2,318 reviews. And you can judge it yourself. Run water through one at home inside your 30 days.
Does it remove viruses, chemicals or heavy metals?
No. It removes 99.99% of bacteria and protozoa. It doesn't remove viruses, chemicals, heavy metals or salt. Boil or add tablets when viruses are a concern. Don't drink water you suspect is chemically contaminated.
Is it hard to pull on? I'm 70.
The first few sips take the most effort, so prime it with 3 to 5 draws. After that it still pulls harder than a regular straw. If that's hard on you, screw it onto a standard water bottle and squeeze, with no pulling at all. Or look at the System, which lets water run through by gravity.
A boil notice went up. Can I use this instead of boiling?
Follow the notice. If you can boil, boil. CDC calls boiling the best way to deal with germs in water. But boiling takes a stove, fuel, a pot and time, and it leaves the grit in. The straw is for when the stove is out, the fuel is gone or you're away from home. A do-not-drink notice is different. Use stored water.
I already have water stored. Why do I need this?
Keep it. Stored water is the clean water you drink first. But at a gallon each, a family of four uses about a case a day. The straw is what you have when the cases are gone.
Aren't tablets enough?
Tablets are a good backup and we'd keep some, because they cover what the straw doesn't. They're slower, they leave a taste and they don't take out mud. The two work well together.
What about my Brita or pitcher filter?
A pitcher is built to improve water that's already been treated. It's not meant for water from a pond or a rain barrel.
I have a cheap straw from a few years back. Is that okay?
Check it against the table on this page: micron size, gallon rating, what it can't remove and the guarantee. Ask whether it's been used or frozen. Cheap marketplace look-alikes are a real problem. Then decide if it's the one you'd hand your grandchild.
We have a generator. Isn't that enough?
A generator keeps the lights and the fridge on. It doesn't fix a main break or a boil notice, and it runs out of fuel. It's a different job.
Isn't this a little paranoid? I'm not a prepper.
Most people who should own one aren't preppers. You don't need a bunker. A boil notice or a dead well pump is an ordinary bad week. This is a short list you buy once and put in a drawer.
Won't the government handle it?
Help does come. It can also mean standing in line with jugs. CDC and the Red Cross both tell households to keep their own supply, and the Red Cross says 2 weeks at home.
How long does it last, and does it expire?
It's rated for 1,800 gallons, which is years of clean water from a single straw. It has no expiration date when stored dry. Keep it from freezing, and let it dry before you put it away. An unused, dry straw is fine in the car. A used one shouldn't sit in a freezing car, and if you think one froze, replace it.
Is it really worth buying more than one?
Yes, if more than one person drinks. Plan one per person, plus one each for the bag, the car and the home. Five singles cost $149.95. The Family Pack is 5 straws, 1 free included, for $79.99. That's $69.96 less, about $16 a straw. Why now? The aisle empties first, and a package takes days. In October 2026 the Pentagon was aiming to run bases 30, 60 or even 90 days without outside power. That plan covers bases, not households. So how long can your kitchen go?
What if I don't like it?
Try it for 30 days. If you're not happy, email us and we'll refund you. Unused or used. Just email hello@minimls.com.

Tested it on pond water behind the house. Clear, no taste to speak of. You do have to pull harder than you think at first.
Family Pack made the most sense. One for each of us and one for the car.
Shipping was slower than I like but fair enough. Product is solid.
I keep it in my purse now. Honestly forget it's there.
Read the instructions and prime it. I didn't and thought it was broken. After a few squeezes it flows fine.
Gave one to each grandchild going off to college. They laughed. Then one of them had a boil notice at her apartment and called me.
I had 6 cases in the garage and they take up a whole wall. This doesn't replace all of it but it's what I'd grab.
works good. light. kept one in the tackle box
I was worried I wouldn't have the lung power. It takes a minute but I can do it. The squeeze pouch would be easier, wish I'd bought that one.
Took it on a 3 day trip as a test. Worked every time. Rinse it out after and let it dry like they say.
After the ice storm we were without water for two days. Didn't have to use it in the end but I'd never had a plan before and now I do.
Feels sturdier than I figured for the price. Caps fit tight.
Our small group split a 10 pack. Good price per straw and everybody took a couple home.
It's a filter. If you know that going in you'll be happy.
He's the skeptic in the house. He cut the instructions out and taped them inside the cabinet, so that's a yes from him.
Had a question about freezing in the car. Emailed and got a straight answer the next day.
We're on a well. Power goes out, water goes out. This should have been in my house 20 years ago.
One is 30 bucks, five is about 80. Not hard math.
Well packed, all there. Haven't needed it yet, hope I don't.
Tried tap, rain barrel and creek. Rain barrel tasted a little flat but it was clean looking. No plastic taste.
Was afraid it'd be an odd gift. My brother-in-law asked where to get more.
My only gripe is the pull. You earn your water. But that's the filter doing its job I guess.
Keeps in the console. Took me 30 seconds to decide after I got stuck in traffic for 7 hours in that snowstorm a few years back.
Ordered Monday, here the next Monday. Works as described.
The only good time to buy is before.
When the tap stops, the aisle empties first. Put the bare minimum in the drawer now.
