How to lower the cost of running a CPAP machine
- Lower the humidifier temperature if you do not need it high. The heater is most of the draw.
- Turn off the heated tube in summer.
- Use a smart plug to cut standby draw during the day.
In standby it draws about 2 W, which adds roughly 18 kWh ($2.71) per year if it is never unplugged.
