How Much Does It Cost to Run a CPAP Machine in Manitoba? (2026)
A CPAP without a humidifier draws 10 to 30 watts. With a heated humidifier and heated hose it can reach 60 to 90 watts. Either way, a full night costs a few cents.
A typical CPAP machine (30 W) costs C$0.003 per hour, or about C$0.79 per month at 8 hours a day in Manitoba. Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (10 W) | C$0.001 | C$0.009 | C$0.26 | C$3.21 |
| Typical (30 W) | C$0.003 | C$0.026 | C$0.79 | C$9.64 |
| High (90 W) | C$0.010 | C$0.079 | C$2.38 | C$28.91 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 8 h/day ≈ 88 kWh per year.
One day of a CPAP machine (0.72 kWh) is the same electricity as
- 4.0km in an electric car
- 7.2hours of TV
- 16hours of a laptop
- 80hours of an LED bulb
In Manitoba, with electricity at C$0.11 per kWh (source: Hydro-Québec 2025 comparison, 2025-04), a typical cpap machine costs C$0.003 per hour and about C$9.64 per year at 8 hours a day. That is about 21% less than the national average for Canada (C$1.01 per month), because electricity in Manitoba costs C$0.11 per kWh against C$0.14 nationally. Each C$1.00 of electricity buys roughly 303.0 hours of use.
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 (C$1.93) per year if it is never unplugged.
