General Aire P188 Retainer Clip
The P188 retainer clip is a small but important component of the humidifier. The purpose of the retainer clip is to hold together the two plastic halves inside the drum assembly, securing them to the metal rod running through the middle of the drum. The drum assembly comes preassembled with a retainer clip already inside, but if the clip becomes damaged or otherwise unusable, these replacements are available to quickly get your humidifier back in proper working condition.
