Our large soft silicone mouthpiece enables better control during suction and is very efficient which means you will take half the time to clear your baby's nasal passage. We also use medical-grade, BPA-free and Phthalate-free silicone instead of plastic because of its antimicrobial properties so it is safe for babies as well as parents! Don't forget, we put this in our mouth day in and day out so hygiene is key!
