Dirty in.
Drinkable out.
Short clips from kitchens, creeks and power outages, filmed by the families who keep one in the drawer.
Your tap runs on things you don't control
It takes electricity to push water to your house. When the power, the plant or the pipes fail, the tap fails with them.
-
Power outage
A storm takes the power
Hurricanes, ice storms and floods cut the electricity, and the pumps stop with it.
-
Boil notice
A notice lands on the door
One do-not-drink advisory can leave a whole town boiling every drop for days.
-
Burst main
A main bursts overnight
No warning, no water. Everyone drives to the same store at the same time.

Questions? Straight answers.
Still unsure about something? Ask our support team.
What does the Shield straw filter out?
It removes 99.9999% of bacteria, including E. coli and salmonella, and 99.9% of protozoa, including giardia and cryptosporidium. It also traps dirt and sediment, and the carbon stage reduces chlorine, odors and bad taste.
It is made for fresh water that is dirty but not chemically contaminated: creeks, lakes, rain barrels, and tap water during a boil notice.
What does it not filter out?
Better you hear it from us. The straw is not rated for viruses, salt (it will not make seawater drinkable), heavy metals such as lead, fuel, oil or industrial chemicals, nitrates, fluoride, or radioactive contamination.
If you suspect any of these, don't drink the water, filtered or not.
Why not just boil the water?
Boiling works, but it takes fuel, a pot and time, and it leaves the dirt in. In an outage you may not have a working stove. The straw needs nothing but water.
Where viruses are a risk, such as floodwater, filter first and then boil or use a tablet.
Which water sources can I use it with?
Yes: rivers, creeks, lakes and ponds, rain barrels, melted snow, and tap water during a boil notice.
Filter, then boil or treat: floodwater.
No: seawater, pool water, and water near fuel spills, farm run-off or industrial sites.
How long does one straw last?
One straw filters up to 4,000 liters, approximately 1,050 US gallons. This is filtering capacity, not water stored inside the product.
How long can it sit on the shelf unused?
More than 10 years, unused and sealed. Shelf life and filtering capacity are separate: shelf life is how long it keeps in storage; capacity is up to 4,000 liters, approximately 1,050 US gallons.
What comes in the box?
The straw, a 1 liter squeeze pouch, a backflush syringe, a clear tube for gravity mode, a lanyard and a carabiner.
Can kids and older adults use it?
Yes. Anyone who can drink through a straw or squeeze a bottle can use it, and because it threads onto a bottle, nobody has to kneel at the water's edge.
Most families choose the 5-Pack
One straw per person. One for the car. Done.
