There’s nothing more frustrating than having to throw away a perfectly good water bottle when you hit the security checkpoint at the airport. Especially since when you’re traveling, staying hydrated is usually the last thing on your mind. From getting all your travel documents are in order (thanks iPhone!) to ensuring all your worldly possessions comply with federal travel regulations, airports can be a pretty stressful place. Determining when and where you’ll find your next sip of water more often than not falls to the back burner.

Due to the ban on liquids in containers larger than 3.4 ounces, many opt to simply wait until after they’ve gone through security to worry about purchasing a bottled beverage on the other side of the security checkpoint because for those seeking anything but plain water from a water fountain, the only option is usually to purchase a mainstream beverage from a store, or order something from a restaurant.

But for those of us who enjoy flavored water on the go without the waste or hassle of other beverages, Cirkul has been a lifesaver. Despite the safety regulation, it’s still possible to bring through bottles that are larger than that as long as they are empty--and that’s where Cirkul comes in.

With Cirkul, you get through TSA without a problem, refill bottle on other side of security, plug in your favorite flavored cartridge, save money on overpriced drinks, and most importantly… hydrate your fine self!
