Indoor Air Quality: The Ventilation Factor

7 月 28, 2026 · technical-guide

What IAQ really means

Indoor Air Quality covers carbon dioxide, particulates (PM2.5), humidity, and volatile compounds. Poor IAQ causes fatigue, headaches, and lower productivity — a hidden cost in every building.

Ventilation first

Mechanical ventilation with controlled fresh-air rates dilutes contaminants. Demand-controlled ventilation (DCV) adjusts airflow by CO2, saving energy while protecting air quality.

Filter and balance

Proper MERV or F-class filters capture particulates; balanced supply and return keep pressure stable. Pair filtration with humidity control (40 to 60 percent RH) to limit microbes and static.

anRens control modules support CO2-based DCV and can report IAQ trends to the BMS, turning air quality from a guess into a measured metric.
