VIVOSUN 6" Pre-Filter Cloth for Inline Carbon Filter - White

The 1.8mm thick PP cotton creates a protective barrier that captures large particles like hair, dust, lint, and pollen before they reach your carbon filter's charcoal bed. This prevents these contaminants from clogging the porous charcoal surface, maintaining the filter's odor control effectiveness and significantly extending its operational lifespan.
