How this is calculated
- Annual energy use is the figure ENERGY STAR lists for this model under typical test conditions. It is not measured in your home.
- Yearly cost = annual kWh × your rate. Monthly cost is the yearly cost divided by 12, a flat average. Five-year cost keeps the rate constant; prices will change.
- Statewide averages are not your utility’s tariff. Use your bill’s rate for a closer number.
- We do not estimate watts or hourly cost: the source data does not include them.

What room size is it rated for?
ENERGY STAR lists this model for rooms up to 250 sq ft. The figure comes from the clean air delivery rate, so a smaller room cleans the air faster than a room at the limit.
What does the integrated energy factor mean?
It is the clean air delivered per watt of power, in cubic feet per minute per watt. This model is listed at 6.5 CFM/W. A higher number means more clean air for the same electricity.
