Collection: IAQ (Indoor Air Quality)

Indoor Air Quality (IAQ) affects health and productivity, with pollutants like mold and VOCs causing issues, while good ventilation improves well-being, and sensors help manage these conditions by signaling systems to adjust for cleaner air, reducing headaches and fatigue. E-Controls offers a number of options for IAQ sensing from manufacturers Greystone, Siemens and Senva.
