Our Energy Cost Calculator helps you understand exactly how much your air purifier costs to operate. Get accurate estimates for daily, monthly, and annual electricity expenses based on your specific usage patterns.
Look for the wattage rating on your air purifier's specifications label, user manual, or manufacturer website. This is usually listed as "Power Consumption," "Rated Power," or simply "Watts."
Consider how many hours per day you actually run your air purifier. This varies significantly based on room type, air quality needs, and personal preferences.
Your electricity rate (cost per kilowatt-hour or kWh) is listed on your utility bill. This rate can vary significantly by location and utility company.
National Average: $0.14/kWh
Northeast: $0.16-0.22/kWh
West Coast: $0.15-0.19/kWh
Southeast: $0.11-0.14/kWh
Midwest: $0.12-0.15/kWh
Southwest: $0.10-0.13/kWh
Speed settings dramatically affect power consumption. Choose the setting you use most often, or auto mode if your unit has smart sensors.
Review the calculated costs and efficiency recommendations. Use this information to make informed decisions about usage patterns and potential upgrades.
Our calculator provides detailed cost breakdowns and efficiency analysis to help you understand your air purifier's energy consumption and identify optimization opportunities.
Your air purifier's cost per day of operation.
Typical Range: $0.05 - $0.25/day
Most efficient units: $0.05-0.10/day
Projected monthly electricity expense.
Typical Range: $1.50 - $7.50/month
Compare to: One LED bulb ≈ $1/month
Total yearly electricity expense.
Typical Range: $18 - $90/year
Average air purifier: $40-60/year
Shows actual power consumption based on your speed setting. This is often lower than the maximum rated wattage.
Example: A 60W unit on medium speed typically uses 35-40W effectively.
