One of the key benefits of our product line is that you can use them anywhere you go, especially when you travel including on an airplane. There's no specific regulations regarding the use of air purifiers, in general they are perfectly fine for using on an airplane. However, it is important to note that some of our products have lithium ion batteries and as a result there are specific rules regarding how these devices may be packed in your luggage or used in flight. The Travel Services Authority (TSA) and Federal Aviation Administration (FAA) publish their regulations on their website.
If in doubt, make sure you check with your airline before you travel as they and the TSA have the final say on what is an isn't allowed on an aircraft.
