Does the MQ5900 run on batteries?

No. It is an AC-powered compressor, so you need a wall outlet. For cordless use, look at battery-powered portable nebulizers.

Is it suitable for children?

Drive Medical lists it for both children and adults. For young children, follow the instructions that come with the medicine and the device.

What comes in the box?

The unit ships with a reusable nebulizer cup. Check the package contents for masks, mouthpiece and tubing, since these vary by kit.

How does it compare with larger tabletop nebulizers?

It is smaller and easier to move, but larger compressors usually finish a treatment faster and hold more. Choose this one if portability matters more than speed.

The reusable cup and mouthpiece are designed to be washed after each use, following the cleaning steps in the manual. Let the parts air-dry fully before the next treatment.

It is described as quiet for a compressor nebulizer, so it is not disruptive at home. It is not silent, and you will hear the compressor while it runs.
