"Have a plan, be prepared, and make h2o a priority for your emergency kit."

Clean water is a basic need. During an emergency, access to safe drinking water often becomes impossibly scarce. Grayl® purifier bottles empower anyone, anywhere, to quickly make a supply of safe, clean filtered drinking water. Pick up a Grayl and be prepared for natural disasters like floods, wildfires, tornadoes, hurricanes, winter storms, and earthquakes. #purifywateranywhere

No need to boil.


Fill at your sink. That's it. No need to pre-boil your water when using a Grayl Purifier.


Press on a low surface. This could be your wood or carpet floor in your home or a flat surfaced stool. The lower the better. Press using the force of you body weight.


Your water is now free of virus and bacteria and completely safe to drink. You can also use your Grayl multiple times and fill up pitchers or containers for storage.

How it works.

Can Grayl Purifiers be used during 'Boil Water Advisory'?

Yes. A ‘Boil Water Advisory’ comes into effect when municipal water systems that supply a city’s or town’s water supply becomes contaminated with pathogens that could make you sick. Grayl purifiers remove all types of waterborne pathogens.

Do Grayl Purifiers remove Cryptosporidium and Giardia?

Yes. Grayl purifiers remove all types of waterborne pathogens,, including Rotavirus, Hepatitis A, Norovirus, Giardiasis, Cryptosporidium, E. Coli, Cholera, Salmonella, Dysentery, amoebas, and more.

Where Can You Find Water in Emergencies?

If your water supply becomes limited, there are sources of water you can access in your home.

  • Water from your water heater. This is the tank that connects to your tap, faucets and showerheads, not radiant heating.
  • Melted ice in your freezer.
  • Water from the toilet tank (not the bowl), as long as it has not been chemically treated.
  • Pool water, if untreated can be used for washing and running your toilet. In a pinch, you can also use your Grayl to purify pool water. Be sure to strain out debris using a handkerchief or t-shirt before purifying.

Don’t forget sources from outside your home (must all be purified with Grayl before drinking):

  • Collected rainwater.
  • Melted ice in your freezer.
  • Snowmelt.
  • Nearby streams or rivers.
