It's smart, It's Swedish, It's maybe a little strange. It's the doctor-invented nasal aspirator what actually works! To Use: Place large tube agaist child's nostril (not inside), creating a seal. Use red mouthpiece to snuck out snot. Tips: (1) Spraying saline solution in each nostril will help loosen thick mucus before using NoseFrida. (2) Move tube in a circular motion against nostril. You will hear and see mucus coming out of nose. (3) Change filter after each use to maintain suction.
