Excited back up machine arrives tomorrow

Yes you can. However, I would recommend you get a second climateline hose as soon as you can so you con't have to keep swapping it back and forth.

I will get a back up of everything.

Or two, don;t forget Murphy's Friend he uses XPAP too! Jim

Dang that murphy is getting expensive.

I know you are using a heated hose right now....and I know the dog already ate the first heated hose...and heated hoses can be expensive.
There's always a non heated cheap hose that could be a spare for an emergency and wouldn't cost much.

If money is tight...when thinking of spare mask ...think of the part that is most likely to maybe suffer a catastrophic failure...the silicone part. The cushion or nasal pillow. Make sure you have a spare even if maybe not quite the perfect size.
If plastic breaks we can usually do a short term repair with some tape or something...kinda hard to tape a torn silicone cushion/pillow.
Example...I use a nasal pillow mask...I use the size small nasal pillow and my complete package comes with 3 sizes...Until I can afford to get another complete package if something happened to my nasal pillow in the size small I could get by with another size if I had to.

You don't have to get duplicates of everything right this minute. You can take your time and plan and get maybe a low cost alternative like a non heated hose. No, not ideal of course but better than no hose or a hose that the dog ate half of it and zero chance of taping it back together.

I think it was 6 months before I had duplicates of everything with the exception of the water chamber....I didn't get a spare chamber until I got a spare machine about 4 months into therapy.
