How do I replace the Recharge Cell?Updated a month ago

Replacing the Recharge Cell takes only a few seconds:
Turn and remove the old top cover.
Remove and discard the retention clip on top of the Recharge Cell by squeezing it inward. (Note: some models may not have a retention clip.)
Slide the old Recharge Cell out of the purifier and discard it.
Slide the new Recharge Cell into the unit by aligning the keyholes.
Install the new top cover provided with the Recharge Cell.
You will know it is working when the green light turns on.
