ERV in New House Yes or No?

Very interested in installing an ERV for our new house (Michigan). Builder quoted a Renewaire EV Premium M installed directly into the return air, which as I understand will have the furnace fan run anytime the ERV is running.

I understand that running it with it's own ducting system is the preference, but it would be a significant effort and cost for the size of house. Will running through the furnace be worthwhile to improve air quality, without adding too much of cost for running the furnace?
