How can I get BMC masks in the US?

Hi, folks. Some of you might have already seen in the last few days that I've been trying to figure out how to travel with my (Airsense) CPAP machine while being prepared for a possible power outage in Mexico. There are portable battery packs available, but they would only power my machine for about 2.5 hours in its current configuration. The main problem is the humidifier, which is very power intensive.

In a search to reduce reliance on the humidifier in an emergency situation I found that a company called BMC makes masks with an integrated HME (waterless humidifier) for travel (https://www.cpaponline.com.au/shop/cpap ... nv7S1ocu7u). I remember trying a waterless humidifier like this one https://www.cpapstoreusa.com/product/un ... h7Ec&gQT=1 a few years ago, but I combined it with my regular mask so it wasn't really effective. I think for HME to work the device has to be quite close your mouth so the hose has to be short.

I would try to try one of these BMC masks, but I can't figure out how to get them in the US. Does anybody know? Or perhaps you could give me suggestions for other HME masks (but not the Resmed ones that only work with AirSense) or regular masks that work well with HME. I would be grateful for any leads.

Maybe silly question, but have you talked to the company?

I tried emailing them but no response. I think they might be Chinese. Australians seem to be able to get the masks but I'm in the US.
