Thank you for viewing. If you use a 5V1A adapter, it may not provide enough power to the inhaler, and it may not be able to nebulize. Please try using a 5V2A adapter. 【Easy to inhale with fine particles】 turns the medication into a fine mist of 4μm or less. The active ingredients of the medication reach the mucous membranes of the bronchi and lungs directly just by breathing naturally. Inhaled medication has a greater effect with a smaller amount than oral medication. Nebulization particle size: Approximately MMD4μm Nebulization capacity ≥0.2ml/min A compressor nebulizer compresses air that has passed through an air filter using a compressor, aerosolizes the medication, and nebulizes the medication into a fine mist. It is also highly compatible with viscous medications, so it nebulizes most medications. It can also be used with suspensions such as Pulmicort (budesonide inhalation solution, BIS) and Aleve, which tend to clog in mesh-type nebulizers! After use, simply remove the medication cup and mouthpiece or mask from the air tube and wash them with clean water. The simple structure makes it easy to clean and maintain. You'll be free from the worries of frequent clogging with mesh-type nebulizers, making cleaning a breeze!! And, the medication cup replacement is less frequent than with mesh-type nebulizers. Four anti-vibration rubbers are used at the bottom, effectively reducing the vibration and noise produced during the operation of the compressor. In addition to the quiet design so that children are not afraid, we have focused on ease of use for novice moms and dads. 【Please note】 Continuous use is possible for a maximum of 30 minutes each time. It is recommended to take a break of 30 minutes or more between uses.
