Replacement JonEvac® charcoal filter cartridge.

This JonEvac® charcoal filter cartridge is a patented component of the JonEvac® toilet seat ventilation system. It removes the unpleasant odor that was extracted from the toilet bowl, and kills the odor causing fecal bacteria. Fresh clean air is released into the restroom. The special charcoal filter is located inside the JonEvac® filter fan housing unit, and should be replaced every 1-2 years depending on the frequency of usage. It is made of durable, long lasting material for reliable performance.
