Can an ERV reduce indoor CO₂ levels?

views: 30  time: 2026-10-10

An ERV can help reduce indoor carbon dioxide (CO₂) concentrations by replacing CO₂-rich indoor air with outdoor air, provided that the outdoor airflow and air distribution are adequate for the occupancy.

The result depends on occupancy, ventilation rate, room mixing, outdoor CO₂ concentration, and operating conditions. CO₂ monitoring can help assess ventilation performance and support demand-controlled ventilation when the system has compatible sensors and controls.
