Neither the Transportation Security Administration (TSA) nor the airlines impose limitations on traveling with the Naväge Nose Cleaner. It can be packed in your carry-on or checked baggage.
The situation with SaltPod capsules is a little different. According to the TSA website, passengers may bring up to a quart-sized bag of liquids in a carry-on. The individual items must be in small containers that are each 3.4 ounces or less. According to 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, so you can carry on as many SaltPods as can be placed in a quart-sized Ziploc bag (it's a lot!). You can easily pack up to a dozen SaltPods and still have room for other liquids.
Even better, have you considered the Naväge Travel Case or Travel Bag? They are designed to conveniently hold the Nose Cleaner and SaltPods, and to protect them from being damaged. These are a great way to travel with Naväge, and they are 100% TSA compliant for carry-on and checked baggage!
