The BabyComfyNose Nasal Aspirator uses your own suction to remove mucus from your baby’s nose. Before you say ‘Yuck’, the patented design of the aspirator and the tissue filtration system eliminate any possibility of contact with mucus and germs. Household tissue wadded up and inserted into the body of the aspirator functions as a highly effective and super-absorbent filter. Simply throw away the tissue when you are done and toss the entire unit into the dishwasher. Put all the pieces, unassembled, into the nylon mesh bag for drying.
