Nebulizer ideal for situations with severe nasal congestion caused by colds or allergies. It is not diluted, so all the minerals and trace elements from the sea (including potassium, calcium, magnesium and sulfate), which are so beneficial for the proper functioning of the nose, are preserved. The seawater emerges at medium strength, allowing for effective rinsing and extraction. No propellant gas and no preservatives. Can be used as often as desired and for as long as necessary.
