New, unopened product. MEDIKEN Nebulizer Inhaler ME109 【All-around technological innovation - easy to use and convenient】 The "ME109" from MEDIKEN is the latest mesh-type nebulizer that has achieved all-around technological innovation. It employs the latest mesh technology to convert medication into an ultra-fine mist with a particle size of approximately 3.5μm. This allows the active ingredients to smoothly reach the trachea, bronchi, and alveoli with each breath, enhancing the effect on the deep tissues. 【Mesh part replacement】 With the unique mesh part replacement technology, you can replace only the mesh cap without replacing the medication cup. This significantly reduces the cost of consumables and is economical. With one included replacement mesh cap, you can immediately replace it and continue using it even if the mist suddenly stops. It instantly eliminates the anxiety of not being able to produce mist and balances cost reduction and convenience. 【Automatic cleaning function to prevent mesh clogging】 After use, simply add distilled water to the medication cup and long-press the power button to activate the automatic cleaning mode. This effectively washes away the medication remaining in the mesh part and prevents clogging. It can maintain a clean state for a long time and always demonstrates stable atomization performance. 【Digital display & multi-function】 Adopting the latest digital display, improving visibility and operability. Adult mode: Atomization rate of approximately 0.3-0.4 mL/min for efficient inhalation. Child mode: Atomization rate of approximately 0.2-0.3 mL/min for gentle inhalation. Countdown function: Selectable from 30 minutes / 20 minutes / 10 minutes. Battery level indicator: Reduces anxiety about battery depletion. Medication depletion detection function: Automatically detects the anhydrous state in the medication cup. 【Quiet design - comfortable for the whole family】 Unlike compressor types, it uses an ultrasonic mesh method, so the operating noise is very quiet. Babies and young children can use it with peace of mind, and it can be used at night without worrying about the surroundings. It comes with three types of masks: adult mask, child mask, and mouthpiece, to meet the needs of the whole family. 【Lightweight and compact for convenient portability】 Lightweight and compact design, useful for outings, travel, and business trips.
