AirProject Plus Description Fast and quiet ultrasonic nebulizer. The product provides fast and quiet nebulization, making it suitable for children as well. The AirProjet Plus comes in a convenient travel bag that protects it from bumps and scratches. Included accessories include a connecting tube, mouthpiece, fork and a 2-in-1 soft mask that easily adapts to both adults and children. How to use There is no internal piston: nebulization occurs thanks to high-frequency sound waves that propagate through the water and break down the solution, turning it into a fine mist. Then there is a special pre-filled sealed chamber, into which there is no need to add water: it is immediately ready for use. Once you are done, it is easy to clean. Format 1 piece. Code 0203820410000
