They invented a water filtration device to make life easier while camping, but it's also selling well with other people.
The filtration device has inspired them to create distillers, and open a store carrying anything you might need to survive.
"Surviving is basically have a plan, be prepared, protect your family," explained SHTFandGo.com owner Nicole Gilbreth.
They've seen sales go up with events like the Flint water crisis, since the filtration devices can clear out lead, fluoride, chlorine, and other minerals and chemicals in water.
"We're big on surviving ourselves, so it's nice to be able to have drinkable water, food to eat and other survival stuff," she said.
Gilbreth admits there are other systems available for filtration and distilling, but said many are more expensive. She said people like that the products are made in the United States. In fact, they build them right in their store.
Kara Menzel, who bought one of the counter-top units last year, said she can taste the difference in her water.
"Even out of a water bottle, you're still drinking that stuff. So having the 7-step stage where it's taking out all that stuff, it's like you're drinking crystal clear water," explained Menzel.
