Replacement cartridge for use with WellisAir Disinfection Purifier system.

At around 90 days of continuous running, WellisAir Customers will begin to see the cartridge warning light coming on. In about a week after that their units will shut down in fail safe mode unless a new cartridge is inserted.
They may notice that there is some oil still remaining inside of their old cartridges. The cartridges expire after about 90 days of continuous running time. In various environments different amount of oil is needed to produce the OH, so all of the cartridges are overfilled.
