A fresh air intake is an HVAC component that brings outdoor air into a building to improve indoor air quality and maintain healthy ventilation. It helps dilute indoor pollutants, control humidity, and replenish oxygen. Proper placement and filtration ensure incoming air is clean and balanced with exhaust airflow.

Fresh air intakes balance indoor air quality and comfort.
An office building uses a dedicated outdoor air intake to dilute VOCs and CO2 from occupants and equipment while keeping indoor humidity in a comfortable range.
Keep fresh air intakes away from exhaust vents or loading areas, and clean intake grilles and filters to maintain air quality.
