According to information published by the TSA on their website, you are allowed to bring up to a quart-sized bag of liquids in your carry-on bag. The individual items must be in small containers that are 3.4 ounces or less each. According to the TSA, "Placing these items in a small bag and separating them from your carry-on baggage facilitates the screening process. Pack items that are in containers larger than 3.4 ounces or 100 milliliters in checked baggage."
The good news is that each Naväge SaltPod contains one-quarter of an ounce (0.25 oz.) of saline concentrate liquid, so you can carry on as many SaltPods as can be fitted in a quart-sized Ziploc bag. You can easily pack up to a dozen SaltPods and still have room for other liquids.
Even better, have you considered the Naväge Travel Bag? It’s designed to hold the Nose Cleaner and up to 14 SaltPods! It’s a super-convenient way to organize Naväge while traveling, and it’s 100% TSA compliant!
