This JonEvac® filter fan housing unit is a patented component of the JonEvac® ventilation system. It includes an exhaust fan that sucks odor and bacteria out of the toilet bowl, and a special charcoal filter cartridge that removes odor and kills the odor causing fecal bacteria before releasing fresh clean air into the restroom. The filter fan housing unit is a component part that connects to the JonEvac® ventilated toilet seat with two vacuum hoses. It is made of durable, long lasting material for years of reliable performance.
