Air Purifier cost vs U.S. average
At the state average rate, an air purifier in West Virginia costs $0.39 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. West Virginia prices that energy at 16.06 ¢/kWh, against a 19.32 ¢/kWh national average.
Air Purifier operating cost estimate in West Virginia
| Time period | Energy use | Cost |
|---|---|---|
| Per hour | 0.05 kWh | $0.01 |
| Per day | 0.40 kWh | $0.06 |
| Per month | 12.0 kWh | $1.93 |
| Per year | 146.0 kWh | $23.45 |
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.
