I came here to say exactly this. I'm in Toronto Canada and just renovated a duplex, i was required to install ERV's to exchange the air. VOC's from off-gassing is unavoidable with present building materials, so the best we can do is replace the air as often as possible to minimize the impact. They're not expensive, and the impact to air quality is massive.
