I. Product Introduction
G4 Pleated Air Filters are medium-efficiency filters designed for HVAC systems and industrial ventilation. With their pleated design, they offer extended surface area for improved particle capture while maintaining low airflow resistance. These filters serve as excellent pre-filters for higher efficiency systems (F7-F9, HEPA).
