I personally didn't use automated air vents. You can also use heat recovery ventilator (Air ex-changer). It's safe and didn't required much efforts to install. There are different types of air ex-changer are available in market but I suggest to use Fantech AEV 1000. Fantech AEV 1000 air ex-changer provides proper ventilation in the home or places like garage, your workshop etc,. Benefit of Air ex-changer is that, it's a best buy for summer and winter both the season. It helps you to warm up place in cold as well as dehumidifying the air in summer. You can easily install air ex-changer by yourself or you can also ask professional to install air ex-changer.
