Find out the power consumption of such a unit.
For example, a 100 watt light bulb turned on takes 10 hours to use 1 kilowatt of electricity.
So if a kilowatt of electricity costs say .15c where you live and say this purifier uses 100 watts of power while in use, say 10 hours in a 24 hour period, then it will cost you .15c a day to operate…make sense??
50 watts would take 20 hours of constant "ON" to use 1 kilowatt of power, etc. Do the simple math…..

Air purifiers use almost no electricity. You’ll see no difference whatsoever. Running a single light bulb will use more power in an hour than an air purifier will in a month.
