Mesh nebulizer is the new generation of nebulizer mainly composed of piezoelectric component. To be specific, through piezoelectric component, electric energy is converted into mechanical energy and ultrasonic vibration is generated. Vibration wave will press liquid in medication cup, so as to atomize liquid through micro spray orifice of spray sheet. What is the mesh in the nebulizer made of? The mesh affected by a vibrating membrane and is made of stainless steel. We kindly inform you that mesh/membrane nebulizers are devices sensitive to the use of certain medicines in nebulization. MEDICINES CANNOT BE USED IN THESE: CONTAINING HYALURONIC ACID HYPERTONIC SALT (0.9% Nacl solution is acceptable) BRINE ESSENTIAL OILS OILY SUBSTANCES FOR PROPER OPERATION, YOU MUST ALSO RINSE THE CONTAINER WITH SLIGHTLY WARM, BOILED WATER - AFTER EACH USE. THEN LEAVE IT TO DRY. DO NOT TOUCH OR WIPE THE MEMBRANE.
