That's because they don't want to get sued if you die.
Your machine doesn't really need a surge protector unless you have bizarrely unstable or unregulated electricity. The power supply is rated for normal operation between about 90 and 250 volts, which should handle most situations. In any case, a surge protector only protects against surges, which aren't really frequent unless your power is weird for some reason (like there's a machine shop in the basement or you run a welder or have frequent nearby lightning).
However if you have frequent brownouts or power failures, your best bet would be a UPS that's "always on" APC makes some models like this. There's no "switching time". They work by continuously charging the battery, and running the inverter.
These will smooth out your power, and handle brownouts and short blackouts, however the trade-off is that the consumer-grade stuff isn't bulletproof.
You would need to weight the probability of a failure of your home power against the probability that a $300 UPS would fail.

I'd be worried about UPS damaging the machines if it doesn't like the waveform or something. Have no idea how resilient the machines are to non-sinusoidal UPS machines.

I use a surge protector on all my electronics other than clocks. Ask your electric company about surge suppressors for medical equipment. They may have specific recommendations. If you had oxygen or a respirator, they may even provide it for free because it usually also includes backup support.
Note: most of my surge suppressors are in the $20-30.
RE: surge protector for cpap?
surge suppressors are only good for 1 or 2 brownouts and after that you may as well have nothing! So if you are serious about wanting surge protection, you will need to replace them regularly.

Tongue Suck Technique for prevention of mouth breathing:
- Place your tongue behind your front teeth on the roof of your mouth
- let your tongue fill the space between the upper molars
- gently suck to form a light vacuum
Practising during the day can help you to keep it at night

RE: surge protector for cpap?
Surge suppressors are not affected by brownouts. They only activate when the voltage spikes upwards, not downwards. They are merely a way to put a clamp on the maximum voltage applied and often sacrifice themselves in the process.

RE: surge protector for cpap?
Most surge protectors don't really do much. They just have some capacitors to ground and maybe a an MOV that shports out voltage spikes. Some other said, the external DC supply probably supplies as much protection as you need.

That's why most of them have the little indicator lights that indicate whether the surge protection is still working. Learn what it means and replace when indicated.
And yes, it's surges, not brownouts that tend to eat surge protectors.

A brownout almost always ends with a voltage spike, though.
The surge suppression you get for twenty or thirty bucks isn't much and it is pretty much done for after it gets hit once.

Not inexpensive but a Sola regulating transformer would be perfect for you.
google Sola-Hevi-Duty 63-13-070-6
The 70 watt one is about $321. No semiconductors in these things. Just a ferro- resonant transformer and a big capacitor.
