Either that or I'm going to trash my new CPAP machine!
You could always start with your Nalgene plumbed into your reservoir. Set the Nalgene next to, and at the same level as your reservoir and fill it up to exactly the same level as your reservoir and see what happens. Worst case, the nalgene empties into your reservoir, but not enough to damage anything. Probably, it would just act as a larger reservoir and work? In the end, maybe a low, wide, air-tight bottle filled up to the same level as the reservoir would be the best option - like a sealed hard plastic sandwich container?
The whole idea behind the collapsible
Nalgene bottle is that it is much more travel friendly than a hard container. (see a previous post) I'm also not too sure I would want water that I'll be inhaling coming into contact with a sandwich container almost for certain made in China - from polypropylene - although it is supposed
to be safe and BPA free.
Nalgene bottles are made from 100% virgin resin polyethylene, fabricated in the USA and certified BPA free. That works for me. A few drops of Betadyne, plain old tap water and some vigorous shaking for a few seconds should be more than adequate to sanitize it - the same solution I'm currently using on the CPAP reservoir.
I don't believe a sealed container would work since it would create a vacuum and possibly restrict flow, especially since I'm going to be using very small id tubing. Once again I'm not an engineer and just guessing here. To me it makes sense to have the atmospheric pressure in both chambers the same - since the CPAP reservoir is
pressurized I intuitively think the aux reservoir should be too.
My biggest concern is making the compressor work any harder than it is now. There will be a little extra stress on it since it's going to be asked to fill TWO chambers with air, but as I mentioned I'm only using a 9 setting currently so should have some wiggle room there. It's entirely possible that someone who is using near the highest setting may prematurely burn out their compressor. Caveat emptor! ...and no, I do NOT intend to sell this, but if successful will let the community have access to how I did it. This won't be rocket science.
The only way to know for sure if it will work the way I think
it will is to actually build it - which I intend to do next week.
