The time-consuming task of changing lungs after every class is a thing of the past. Now, each Little Anne stackable is equipped with a 2-way filtration of 99.9% accuracy. Simply snap into place and save time setting up for each class.
The manikin filter is to be replaced after each class where mouth-to-mouth rescue breaths are practiced. When used and replaced correctly, Little Anne airway lungs do not need to be replaced after every class.
