Nowadays, air purifiers are one of the most energy-efficient home appliances that don’t consume a lot of energy. The rated power of a modern air purifier is 50 watts on average. This means it consumes 18 kWh of electrical energy in a month based on daily 12 hours of usage, which will cost $2.2 at 12 cents/kWh energy rate.
Also, it is not necessary to run the air purifier at the highest fan speed settings all the time, the monthly consumption would be much less than the calculated value.
From our air purifier electricity consumption calculator, you can easily find out your monthly usage. Enter your air purifiers power rating in watt, daily usage in hours, and your local energy rate in USD to find out the monthly kWh usage and the electricity bill of your air purifier.
Air Purifier Electricity Cost Calculator:
Formula: Monthly Electricity Usage = [(Air Purifiers Power Wattage x Daily usage hours)/1000 x 30] kWh month, and
Monthly Electricity Cost = Monthly Electricity Usage x Energy charges per kWh in USD
