Air purifiers getting more and more eco-friendly. Modern air purifiers consume on average 50 watts of electric power per 1 hour if running on a maximum speed, which is mostly used by their fan system and other electronics don’t need that much power anyway. Rates for electricity differ from state to state (scroll down to find link on the government-provided table of Average Price of Electricity to Ultimate Customers by End-Use Sector), but if we assume it is 13.45 cents per kWh (Kilowatt per hour) the total cost would be $4.84.

But this price features an air purifier running at a maximum speed 24 hours per day. And most of the time you won’t need that since EPA recommendations are as follows:

  • An air purifier must be ran at low speeds.
  • 12 hours are the maximum recommended time the unit must work.

Down below we have the air purifier electricity consumption calculator which will help you to calculate your daily, monthly or yearly energy usage in USD and kWh.

Air Purifier Electricity Usage Calculator

To properly calculate electricity usage of your air purifiers, enter power in Watts and how much time are you going to run your air purifier per one single day. Our calculator will estimate how much kWh of power will be used per day, month or year as well as costs of running the unit in USD.

Please note: Manufacturers often specify the maximum power of an air purifier running at a maximum speed. Therefore, if you run an air purifier at a lower speed, energy consumption and your electricity bills will be way lower.

We hope our calculator helped you to figure out how much any of the available air purifiers (whether it’s Nuwave, Dyson, Winix, Levoit, Honeywell, Coway, Blueair etc.) use electricity per day, month or year. And having that information you are going to pick the most energy-efficient and money-saving air purifier out there!
