マスクが厚く息が吐き辛い。 故に酸素チューブ、呼吸チューブを使える様にし、通常のマスクに替えて使用してます。

I turned this on when I stepped out of the car at the airport. I took off the device for security and put it in a zip-lok that I brought just for this purpose. To do that, I disconnected the air tube at the device and tucked the end of the tube inside my mask which stayed on my face. Got through security, stopped and immediately put the device back on, left it on for the entire flight until I was inside my rental car at the other end. When I moved my mask aside to have a cup of coffee and a bite on the plane, I left the mask hanging on one ear so that clean air was still blowing. Do try it on at home and get your setup for how you are going to wear the device. I initially had it slung across my chest, fixed near the top. Once I was on the plane, I found that I was a lot more comfortable with the stretchy belt I'd chosen just wrapped around my middle, up high, like a high-waisted belt. That was super comfortable. Also, this will only run on high for 4-5 hours I believe it is, so I also bought a power brick, brought proper cable, and ran it off the power brick when its own power ran out. The seller has stated in Questions/Answers that it is ok to run it off a power brick. But, there is a limit on the size of a power brick you can bring on an airplane. Check on that limit to make sure they will allow yours in your carry-on. I had way more power than required. I also hung a negative-ion generator from that same belt, next to the device. So I felt very protected. And as I have asthma and can get a bit panicky wearing a mask, this device allowed me to be 100% comfortable and happy with my mask setup. Amazing comfort with cool breeze inside my mask. Last, what convinced me to try this were the videos from the surgical nurse and the dentist (his video is on the original, aluminum version-- but buy this plastic one, it's an improvement). They were 100% right on about the benefits of this device.

I simply can't wear a mask. I just panic. However, a friend told me about this one so I bought it to give it a try. It's the best. The Pump is NOT loud as I read in some reviews. The hose it NOT flimsy as I read in another review. There ARE more than one grommet in the package, as a matter of fact there are 4. and there are plenty of masks too. I'm very happy with this purchase and am so pleased I can wear it without panicking and feeling I have to GET IT OFF ME. I played around with the different levels of air flow and really, level one is enough for me so the battery charge will last lots longer. A big than you to Aurora and a big than you to my friend for suggesting this. It's a game changer for me.

Está muy padre este cubrebocas, si funciona y el ruido que hace el filtro no es tan fuerte aunque tiene 3 velocidades, estaría mas padre si la manguerita pudiera estar mas en medio porque cuando sale el aire lo sientes de un solo lado.

cumple con su objetivo, deberia e traer mas repuestos de cubrebocas, aun que cueste mas.
