Why should I ventilate my attic?
Proper attic ventilation works to decrease heat and moisture within your attic space. Why should you care about heat and moisture? Attic heat and moisture can lead to potential damage to your home and any items that are housed in your attic including mechanical and electrical equipment.
Ventilation is key in reducing your heat and moisture and the potential negative effects it can have on your home. The purpose of attic ventilation is to exchange air in order to prevent heat and moisture buildup. Ventilation is simply bringing in fresh outside air from intake points in your attic space and exhausting out of the highest point of the attic. However, there are a few keys to properly ventilating your attic.
Active vs. Passive Attic Ventilation

Smoke Test Comparison
Sometimes it is difficult to appreciate differences in attic ventilation as you cannot easily see it.
This video demonstrates the comparison of passive ventilation with soffits and ridge vent versus active ventilation with ATMOX controller and fans.
This home has open soffit vents around the perimeter and a ridge vent at the peak. The left side shows passive ventilation using blue smoke. The right side with green smoke is active ventilation using ATMOX fans installed from within the attic underneath the ridge vent.
The difference in the dissipation of the smoke is significant. As you can see, the rate of the turnover of air flow is much higher with ATMOX fans than just passive ventilation.
This simulation demonstrates how buildup of heat or moisture can occur in your attic with only passive ventilation.
Active Ventilation with ATMOX Fans
Regardless of whether you are tackling a heat or moisture issue in your attic, the ATMOX attic fans will get the air moving at the right times to exchange the air and improve conditions. ATMOX attic fans come in a wide variety of styles and mounting options to fit the needs of your attic.
