Replacement JonEvac® charcoal filter cartridge.
JonEvac® charcoal filter cartridge is a patented component of the JonEvac® ventilated toilet seat system. It removes the nasty odor that is extracted from the toilet bowl and kills the unhealthy fecal bacteria. Fresh clean air is released into the restroom for the health and comfort of everyone. The charcoal filter is located inside the JonEvac® filter fan housing unit and should be replaced after 1 year or 2,400 hours of use, whichever comes first.
