The travel size are good for the plane, and TSA compliant. The mist is very fine - which I love. It is great for rehydrating on longer flights. It’s non-scented so others around me don’t complain about any scents.
Great for travel, especially on planes. Blocks out most noise, unless it's directly next to you. IF you're in a quieter area, you will hear white noise. If you switch the noise cancelling off, you will notice a decrease in quality of sound.
This stuff works. It gets rid of smells and doesn't irritate my allergies. I'm not sure how 'antimicrobial' it is, but it makes me feel better using it than not using it. Great on couches and curtains that can't be washed all the time.
