Air Purifier cost vs U.S. average
At the state average rate, an air purifier in South Carolina costs $0.27 less a month than it would at the U.S. average rate.
How much electricity does an air purifier use?
An air purifier draws roughly 25-100 W; we use 50 watts running 8 hours/day. That comes to 0.40 kWh a day — 12.0 kWh a month, or 146.0 kWh over a year — using kWh = watts × hours ÷ 1000.
Air purifiers run continuously when in use, so daily cost scales with hours of operation. Many models have multiple fan speeds that affect power draw. South Carolina prices that energy at 17.06 ¢/kWh, against a 19.32 ¢/kWh national average.
Air Purifier operating cost estimate in South Carolina
| Time period | Energy use | Cost |
|---|---|---|
| Per hour | 0.05 kWh | $0.01 |
| Per day | 0.40 kWh | $0.07 |
| Per month | 12.0 kWh | $2.05 |
| Per year | 146.0 kWh | $24.91 |
These figures use the all-in average rate. Your actual bill can run higher when separately billed taxes, seasonal pricing, and fixed monthly fees apply.
What changes the cost the most?
Two things move this number: your state's rate, which you can't change, and how hard the appliance works, which you often can. For an air purifier, that mostly comes down to fan speed setting, room size, filter condition.

Source & Method
Source: U.S. Energy Information Administration (EIA) Retail Sales of Electricity. Updated: April 2026. Estimates use the EIA all-in average residential rate — energy, delivery, fixed charges, and utility fees together, not just the electricity itself. Fees are inside the rate, not an extra on top; how your own bill splits fixed versus per-kWh charges varies by utility. For what's inside the all-in rate, see hidden electricity fees; for how rates and estimates are defined, see the methodology hub.
