LifeVac is a simple, safe, and effective choking rescue device that can help save a life in the event of a choking emergency. Protect your loved ones on the go with the LifeVac Travel Kit. Each kit provides customers with an adult and pediatric mask. The Travel Kit comes in a zip-up yellow bag—perfect for keeping in your car, luggage, or diaper bag. While the LifeVac device itself never expires, our mask manufacturer recommends replacing the masks every two to three years.
