The Haakaa Cap seals your breast pump to keep it clean and sterile until the next time you need it. Simply pop the cap over the flange of your pump and store away. Your pump will remain 100% contamination free.
Wash in warm soapy water or place in your dishwasher.
Do not place in a sterilizer or boil.
Please note: The cap is designed to keep your pump sterile after cleaning, not to keep your milk spill free or secure.
