D6 SERIES MOUNT Bipolar Ionization (BPI) technology from Eagle X Pro. This BPI technology is designed for installation in HVAC systems for commercial and residential applications and was tested and found effective in neutralizing pathogens such as viruses, bacteria, mold, fungi, and smoke by generating positive and negative Oxygen ions into the HVAC system airflow. This technology generates these same positive and negative Oxygen ions just like those found in nature- that purify and refresh indoor air by neutralizing the harmful pathogens. This unit is intended to bring the health and quality of nature’s air to indoor environments. These units are installed in-line to the ductwork of an HVAC system.
