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. That 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. Since an air purifier doesn’t operate at maximum power all the time, so the real value would be 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 charge in USD to find out the monthly kWh usage and the electricity bill of your air purifier.
Electricity Consumption Calculator:
The formula of Monthly Electricity Usage = [(Air Purifiers rated Power x Daily usage in hour)/1000 x 30] kWh month
Month Electricity Cost = Monthly Electricity Usage x Energy charges per kWh in USD
