They’re more expensive, but are they worth it?
It’s helpful to know why the differences between pure sine wave inverters andmodified sine wave invertersmight matter.
The two main concerns are efficiency and unwanted interference from the extra harmonics in a modified sine wave.

Do You Need a Pure Sine Wave Inverter?
If you answered yes to either of the second questions, then you may be fine without one.
Always check the manufacturer’s recommendations, but most CPAP manufacturers suggest using a pure sine wave inverter.
Don’t be mistaken, it will still work just fine with these devices.
It will work well even in situations where you don’t need one.
However, most electronic devices run well on a modified sine wave.
