HEPA HVAC Power Consumption

    Hello All,

    I was wondering if anybody has noticed a significant increase in power consumption when the "Bioweapon" HEPA filter is turned on vs. when it is not. I was doing a short drive today and turned on the HEPA filter. Efficiency shot up to ~1200Wh/mi in the beginning of the drive and after a mile or two dropped to hover around 500-550Wh/mi. Upon doing the return leg from my destination, I left the HEPA filter off and the efficiency went down to a 290Wh/mi.

    Did anyone else notice this? Or maybe there's something else weird going on with my drive.
