The power use spec is:
Power: 720 watts @ 80°F and 60% RH
Supply Voltage: 115 volt - 1 phase - 60 Hz
Current Draw: 6.4 Amps
We have 120vac and it's drawing 5.8 Amps. But displaying 620 watts.?.
Since it's lower than spec, maybe I'm using a too cheap filter.?.
I'm just happy it's not using more power than spec..
