Sauna Season Coming!! Few years back I learned how to properly ventilate the sauna. Anyone remember this? hahah This was a whole debacle. First, I didn’t give the sauna a proper run time to burn off the oils from the manufacturer, which led me to think I had an allergic reaction to cedar. That wasn’t the case... That shot me into learning more about sauna ventilation, getting CO2 detectors, and doing testing myself Few years later and countless hours and sessions later, I can say these findings were productive. Some would even say I have the best ventilated sauna on this side of the Mississippi. Here’s how to properly ventilate you electric sauna: Pusher fan a few feet above the sauna stove. Set on the LOWEST setting. Puller fan at feet on the opposite side of the sauna. Set on medium. .....Heat rises...... Pusher fan pushes heat away from the stove. Puller fan at feet pulls hot air down. This creates a more even heat across the whole sauna. And it LOWERED my CO2 readings by a few hundred PPM (though I am skeptical of the overall accuracy of the detector). Directionally, the CO2 levels improved dramatically. You can tell when you’re in it as well. It’s obvious there’s more fresh air and a more even heat across the sauna (floor to ceiling). I got the fans off amazon and used dryer vent for running the air through. (pic below of the style of fan I got)
