How to Use This Calculator

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.

1

Find Your Air Purifier's Power Consumption

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."

Where to Find Wattage Information:
  • • Product label on the back or bottom of the unit
  • • User manual specifications section
  • • Manufacturer's website product page
  • • Energy Star database (for certified models)
  • • Amazon or retailer product specifications
2

Determine Your Daily Usage Pattern

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.

Continuous Operation (16-24 hrs):
  • • Bedrooms during sleep + work
  • • High-pollution areas
  • • Allergy sufferers
  • • Pet owners
Scheduled Operation (8-16 hrs):
  • • Home offices during work hours
  • • Living rooms during active use
  • • Occasional-use guest rooms
  • • Energy-conscious operation
3

Find Your Local Electricity Rate

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.

Average US Electricity Rates by Region (2024):

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

Select Your Typical Speed Setting

Speed settings dramatically affect power consumption. Choose the setting you use most often, or auto mode if your unit has smart sensors.

Power Consumption by Speed:
  • • Low: 30-40% of max power
  • • Medium: 60-70% of max power
  • • High: 90-100% of max power
  • • Auto: 40-60% average power
Best Speed for Different Needs:
  • • Sleep: Low or sleep mode
  • • Daily use: Auto or medium
  • • Allergies: Medium to high
  • • Emergency: High speed

Frequently Asked Questions

How accurate is this energy cost calculation?
The calculator provides very accurate estimates based on the specifications you enter. Actual costs may vary slightly due to voltage fluctuations, filter condition, and environmental factors.
Should I run my air purifier 24/7?
For most homes, running an air purifier continuously on low or auto mode provides the best air quality. The energy cost is usually minimal compared to the health benefits.
How can I reduce my air purifier's energy costs?
Use auto mode, keep filters clean, choose Energy Star certified models, optimize placement for better airflow, and consider using timers for rooms that aren't always occupied.
Are air purifiers expensive to run compared to other appliances?
Most air purifiers cost less than $50 per year to operate, which is comparable to a few LED light bulbs. They're much more efficient than heating/cooling systems.
