Secondary Filters

F7, F8, and F9 Filters for Enhanced Indoor Air Quality


Our F7-F9 secondary filters trap the finer, more hazardous particles that escape primary filtration. These filters significantly improve indoor air quality by capturing elements like fine dust, microorganisms, and other airborne pollutants, helping to maintain product integrity and a safe, contaminant-free environment.
