Instead of going inside the nose like the bulb, NoseFrida forms a seal with the outside of the baby’s nostril (creating a vacuum). Parent-powered (mouth) suction is much stronger and effective that the static suction of the bulb or battery-powered aspirators. It is also easy to clean and its hygiene filters prevent mucus and bacterial transfer from child to user. NoseFrida is made of non-allergenic, latex-free, BPA-free, and pthalate-free polypropylene. Manufactured in Sweden.
