I'm currently 'interviewing' some local HVAC companies for a new furnace/air and possible heat pump. All the previous bids include a standard MERV 10 media filter. The last company I spoke with HIGHLY recommended the Totaline CG 1000 Electronic Air Cleaner. Does anyone know if this is preferable over the standard media style and why? Like I said, out of 5 or 6 bids, they are the only ones recommending it.

Thanks!
