Do I need a pre-filter?
A filter is not required. But we do sometimes suggest a simple filter to extend the life of your fan. Dust, pet hair and other airborne particles mix with the growing humidity and become a wet mess. This mixture can foul fan blades and mechanisms. Using some old panty hose material stretched over the inlet to the exhaust fan and secured with duct tape will help minimize this contamination. This “panty hose” filter is easily replaced when you do your regular garden maintenance
