Air purifiers are used to clean air in an enclosed space by continuously passing it through a filter and removing the contaminants present in the air. You can calculate the energy usage of air purifiers here. The power consumption of air purifiers ranges from 17 watts to 100 watts. A typical water heater consumes 30 watts of power.
Enter the wattage, hours of usage, and cost per kWh. The energy usage calculator for air purifiers gives you the total energy consumed by them. Also, you can find how much power your air purifier consumes.

Terms and definitions:
Wattage:
Power usage of the device in watts as mentioned on its label.
Cost per unit:
The average cost per unit charged by the electric utility. Every country has different tariff rates. Visit: Global Electricity prices for details if you don’t know how much the utility company charges you per unit or kWH.
Units per day:
The number of units of electricity consumed by the load every day considering the entered operation hours.
Hours of usage:
The number of hours the load is used per day.
The electricity usage depends on the wattage and the number of hours of usage. The utility company charges you for the total kilowatt-hour of energy you have consumed. Kilowatt-hour is the product of the power consumption of the load and the number of hours of usage.
Power consumption of air purifiers
A typical water heater consumes 0.3kWh of energy per hour of usage. That means an hour of usage can cost you 0.036 cents.
An air purifier sucks the surrounding air and passes it through a series of filters. Some air purifiers have UV filters to kill the microscopic organisms present in the air. The power consumption of air purifiers is very low when compared to that of other home appliances.
