Coarse filters capture larger particles like dust and sand while ensuring low airflow resistance, quieter operation, and energy efficiency. Ideal for ventilation systems, they extend filter lifespan and protect HVAC components. CleanFilter Coarse filters offer premium materials, high dust-holding capacity, and certified performance for cleaner indoor air.

G4 filters are effective at trapping medium-sized dust particles, sand, insects, lint, and even some larger pollen particles. They provide sufficient filtration to keep ventilation systems running smoothly and cleanly.
