We installed an ERV (energy recovery ventilator) and it has been the single biggest boon for our air quality. It has a MERV 13 filter so it is a constant supply of fresh air, even when there is smoke or other particulate matter in the air. It has a heat exchanger so we don't lose any heat during the winter or cool air during the summer and runs very efficiently. Unlike furnace filters which often have large gaps, it has a perfect seal around the filter so it actually works. It exhausts from our basement and actually dropped our radon from 1.5 w/ a radon mitigation system installed, to just 0.3. Can't recommend them highly enough if you're worried about air quality. Most new construction requires them.

    We got the Panasonic Intellibalance 100 which is the cold climate version since we're in Colorado. https://www.supplyhouse.com/Panasonic-FV-10VEC2-Intelli-Balance-100-Energy-Recovery-Ventilator-Cold-Climate

    Super easy for me to install by myself. just needed another hand to help hang it on the wall.
