— The Problem

When the grid goes down, the essentials go with it.

Clean water is the first thing you lose, and the hardest to store.

 

The power follows.

 

Your furnace probably needs electricity too, even if it burns gas. 

 

So in a winter outage, the heat goes with it.

 

Then the phone dies, and you can't hear what's happening or where it's safe.

 

Most gear on the shelf was built for a weekend outdoors.

 

PureFlow is built for the day the tap stops and stays off.

— From Our Customers

What our customers say.

Real people who got ready before they needed to,across the straw, the kit, and the radio.

Robert T

Verified Customer

Water straws were exactly as advertised. So very easy to use. Feel well prepared now in the event of an emergency, knowing I can drink clean water. Thank you!!

Natasha J

Verified Customer

"When the storm took our power, the TV and wifi went with it. I turned on the weather channels and we just listened. Knowing what was headed our way, and when, kept everybody calm. My husband kept asking me for the updates. For once I was the one who knew."

Max S

Verified Customer

"I stopped pretending things were going to go back to normal. Between the war, the gas prices, the grid stuff... I just decided I'm done hoping for the best and not doing anything about it. Got one for every person in my house. If nothing ever happens, great, they sit in a closet. If something does, my kids are covered. That's all I needed to know."

— Tested & Verified

You don't have to take our word for it.

The filter is the core of what we make. It's in the straw, and it's inside the 14-Day Kit. So we test it independently and tell you exactly what it does, and what it doesn't.

Third-party tested for what matters

Independently tested for bacteria and protozoa removal. Filters 99.99%, and we're clear that it doesn't remove viruses or chemicals.
Title

Pressure-tested build

Checked for membrane integrity and leak resistance, so it holds up when you finally need it.
Title

Real filtration science

Built on a 0.01-micron hollow-fiber membrane, finer than common hiking straws.

— Why PureFlow

Built for grid-down. 
Honest about the rest.

Everything we make is built for the day the grid actually goes down, not for a weekend outdoors.

Built for real emergencies

The straw filters for a long emergency, not an afternoon hike. The radio powers itself four ways, so a dead outlet won't stop it. The kit packs two weeks of readiness into one bag. The sleeping bag packs small enough for a glovebox, so every car gets one.

Premium build, no knockoff feel

Cheap gear fails the day you need it. Our filter is third-party tested and pressure-tested. The radio is water-resistant. The kit ships complete and ready to grab.

We tell you the limits

We're clear about what our gear does and doesn't do. The straw filters bacteria and protozoa, not viruses. The radio receives broadcasts; it doesn't replace a warning siren. The sleeping bag holds your heat, but it isn't a rated bag, so put something between you and cold ground.

— Straight Answers

The questions worth asking.

Does PureFlow remove viruses?

No. PureFlow filters remove 99.99% of bacteria and protozoa. They don't remove viruses, chemicals, or heavy metals. For viruses, pair the straw with purification tablets or UV. That layered approach is how serious preparedness works.

How long does the filter last?

Up to 1,800 gallons per straw. It has no expiration date when stored dry. Don't let it freeze, and dry it before you store it. Once it's been used, plan on about six months of life.

Will the sleeping bag keep me warm on its own?

It helps you hold your heat. It reflects your radiant body heat and blocks wind and rain. But it's not a rated sleeping bag, and it does almost nothing against cold ground. Put a pad, cardboard, or a car seat under you and it works a lot better.

Does the radio alert me during a storm?

It receives NOAA weather, AM, and FM broadcasts, so you can tune in and hear what's happening. It doesn't auto-alert or sound its own warning. You turn it on and listen. It also charges your phone for essential calls and texts.

Is the 14-Day Kit two weeks of food?

No. It's built to keep one person covered through the first two weeks: water, warmth, shelter, first aid, tools, light, and signaling. It includes a short-term food ration and a fishing kit, not two weeks of stored meals.

Is the sleeping bag waterproof?

It's water-resistant. The shell sheds rain and splashes, but the opening isn't sealed, so don't count on it in standing water. Store it cool and dry, and repack it gently. The film can tear once it's punctured.
