😷 Nebulizer

A nebulizer being flagged is not a cause for concern — screeners are familiar with medical devices and will simply inspect it visually or swab it for trace detection. It may not fit the typical bag profile on the X-ray, which can trigger a secondary check, but it will not be confiscated. Telling the officer upfront that you have a medical device can speed things along.

Nebulizers are permitted in carry-on baggage in the US, UK, EU, Canada, Australia, and virtually every other aviation system — they are a recognized medical device and receive consistent treatment globally. There are no regions where a nebulizer is routinely prohibited from the cabin.

A doctor's letter is not required to carry a nebulizer through TSA or most equivalent agencies, but having a prescription label on your medications or a brief note from your doctor can be useful if officers have questions. Nebulizer medications are exempt from the 100ml liquid rule, so you can carry the full prescribed amount in carry-on without fitting it into your quart-sized bag.

Keep your nebulizer in an easily accessible part of your carry-on bag so you can remove it quickly if asked. Inform the security officer before your bag goes through the X-ray that you have a medical device — this sets expectations and usually leads to a faster, more courteous inspection. Store medication in its original labeled containers to avoid any questions about the liquids exemption.
