FULL CONTROL OVER SUCTION POWER: No need to overexplain. The Nosiboo Eco Nasal Aspirator is powered by your own lung, so you can decide how strong you wish or can perform suctioning. NO FILTER NEEDED: The aspirator works with Nosiboo’s exclusive patented concept which prevents the nasal mucus from getting out of the suctioning head. It doesn't require any filters, so you save your money and time!. BPA-FREE: Nosiboo cares. That is why we exclusively use materials that are absolutely harmless to humans. We made this sure by strict and thorough testing. EASY-TO-CLEAN: Our engineers had been working hard to create a device that makes the life of mothers and their little ones easier. That is how the Colibri head was created. The head is the only part of the device that needs cleaning after a nose cleaning session. It can be taken apart and simply washed under running water. SILENT AND GENTLE: Handy, silent and gentle – an ideal choice for nights. The nose tip is made of soft, BPA-free silicone to make sure that it does not irritate the baby’s nose.
