Improve indoor air ventilation by reducing CO2 levels. The quality of indoor air in homes, offices, schools, and other workplaces is important not only for the occupant’s comfort, but also for their health. Poor indoor air quality (IAQ) has been tied to symptoms like headaches, fatigue, trouble concentrating, and irritation of the eyes, nose, throat, and lungs. Melchers Wall Mounted Energy Recovery Ventilator (ERV) promotes indoor air ventilation. Equipped with a carbon dioxide (CO2) sensor, the speed automatically changes to bring in fresh outdoor air. This dilutes high levels of CO2, formaldehyde, and other harmful gases. HEPA filters inside the unit purify PM2.5 pollutants of up to 99%, giving you cleaner and fresher air. The intelligent heat exchanger inside the unit prevents temperature loss during an air exchange process.
