Why choose it

The MicroAIR GO U300 is a true pocket nebuliser. It weighs only a few hundred grams and fits in the palm of your hand, yet it delivers hospital-grade particle sizes. Because it runs on batteries, you’re never tied to a wall socket—use it on a plane, in a car, or during a power cut. The included adult and child masks, mouthpiece, and mask adapter mean the whole family can share one device (with proper cleaning). And with a 3-year warranty, OMRON stands behind its durability.

Ideal use cases

• Daily asthma maintenance at home, especially for children who need quiet treatments
• Travel and commuting—keep it in your handbag or backpack for sudden symptoms
• COPD management where portability and ease of use are essential
• Use in shared spaces like offices or hotel rooms without disturbing others
• Emergency backup when a compressor nebuliser is too bulky or power is unavailable

Good to know

Cleaning is straightforward: rinse the medication cup and mesh cap after each use and air dry. The soft pouch keeps everything together, and the device automatically shuts off when the medication is finished. For faster treatments, use the mouthpiece rather than the mask. If you plan to use it daily for long sessions, consider the optional AC adapter to save on batteries. Always follow your doctor’s instructions for medication dosage and frequency.
