Does an ERV/HEV blow cold air in the winter? – GreenBuildingAdvisor

I am planning on installing a Panasonic Intelli-Balance 100 Energy Recovery Ventilator, FV-10VEC2, in my house, and I am wondering which rooms to put the exhaust and supply vents in. I read that exhaust typically goes in a bathroom and supply typically goes in a bedroom. For the latter, does the supply vent blow cold air in the winter? I don’t want to make the bedroom drafty, and it only has a single forced air heating vent that’s not designed for the extra load of a constant cold breeze (mainly, if the door is closed the thermostat on the main floor won’t know that room is getting colder).

The other option I can think of would be to supply air to the hallway outside the bedrooms. That is above a vaulted living room, so it is probably the warmest part of the house and some air mixing would be welcome. Maybe the exhaust could go in the bedroom so there is always some air mixing?

I am located in Denver, CO, where the design temperature is around 0F (although it is the beginning of January and it’s 60 degrees today).

A secondary question, is there any filter I can add that will remove wildfire smoke? I see they have a MERV13 option, but I don’t think that will quite do it. Fantech makes a MERV13 filter box with a larger filter, but that isn’t any better, the filter is only a little cheaper, and it’s not clear if a standard size furnace filter would fit. The Panasonic ERV is only rated for 0.5″ wg, so maybe it’s not possible to add a better filter. There was a Matt Risinger video that showed a MERV17 filter on a Zhender ERV, but that kind of system is not in the budget.
