|1. RADIAL INLET & OUTLET
The unique curved form of the air inlet and outlet provides greater open area than any other V-shaped filter, resulting in less resistance to air flow, 30% more open area on the filter inlet and 60% more open area on the outlet than traditional V-style filters - a key component in achieving the highest airflow.
The PathogenBarrier Filter is rated as a 5-Star filter through the Energy Cost Index (ECI) program. Based upon a five-star scale, the Energy Cost Index is an indicator of how a filter will perform over time. The best rating, 5-Stars, maintains its efficiency over its life and uses less energy to move air through the filter and is the most energy-efficient, longest lasting filter available.
