Some say they pull air from inside house, but with such low CFM, and all the soffit vents that’s not a concern. But pulling from the ridge vent in, well that would be counterproductive, possibly harmful. Cost at about $2k for two large ones from Solar Guys installed, I misspoke if I say cost for reverse airflow would not be a problem.
