Nosefrida Aspirator Hygiene Filters Nose Frida is clinically proven to help improve your child's breathing, feeding & sleeping by safely relieving congestion. The Nosefrida Nasal Aspirator comes packaged in its own protective case together with 3 replacement filters. The Nose Frida nasal aspirator is an effective aid against nasal congestion for small children aged 0-3. Small children cannot blow their noses & this disturbs their sleep, food intake & the general well-being of both the child & the whole family. Nose Frida has been developed & produced by an ear, nose & throat doctor. It meets all the demands for safety & hygiene both for the child & the user. The nasal aspirator does not irritate the sensitive mucous membrane in your child's nose. So why is Nosefrida better than other aspirators? Nosefrida is non-invasive-instead of going inside the nose like the bulb, it forms a seal with the outside of the baby's nostril (creating a vacuum) Parent powered (mouth) suction is much stronger & effective than the static suction of the bulb or battery powered aspirators. Nose Frida is also easy to clean, dishwasher safe, & BPA & Phthalate free.
