Nebulizers are used for respiratory conditions like cystic fibrosis, asthma and COPD to administer medication in the form of a mist into the lungs. There are various types and the ultrasonic nebulizer is known for offering small, quiet and quick administration of a selective list of suitable medications. The Excelvan portable ultrasonic nebulizer is a small portable version with a built in rechargeable battery.

Ultrasonic Nebulizer

There are three main types of nebulizers: conventional, ultrasonic and vibrating mesh technology (VMT). Conventional nebulizers use an air compressor to create a mist and they are usually bulky and loud, reliable but slow.

An ultrasonic nebulizer vibrates liquid medication at a high frequency to change it into a mist. The heat generated by the vibration makes some nebulized medications unsuitable for use by breaking down the molecules. It is important to check with your care provider whether an ultrasonic nebulizer can be used with your medications before purchasing one. The main advantages of an ultrasonic nebulizer are that it is smaller, lighter and dispenses medication faster and quieter than standard nebulizers as well as being cheaper than a VMT nebulizer.

Vibrating Mesh Technology (VMT) nebulizer systems vibrate medication through a wire mesh, which breaks the molecules into the same size and disperses them as a mist. It has the same advantages, it is portable, lightweight, efficient and quiet and in addition a wider range of medications can be used, but they do cost more.


The Excelvan ultrasonic nebulizer is lightweight, weighing less than 500 grams, battery operated and highly portable.

It is highly accessible to anyone with a visual impairment, including blind users. The components have grooves and ridges that make it possible to feel how they slot in, the water reservoir has a palpable line when full and the button is raised and a highly visible dark blue against a white background. The text is small, but not required for use.

There are two small lights on the base unit, one lights up green on activation and the other red when charging is needed. Neither is particularly bright or flashy and should not present any issues for someone with photophobia. Colour is not the only indicator and anyone with colour blindness should not have any issue.


One on the biggest selling points of an ultrasonic nebulizer is how quiet it is when in use. I measured it at about 35 dB. Standard nebulizers are notoriously noisy and in comparison, an ultrasonic nebulizer is whisper quiet. There is no requirement for sound, the unit will turn off automatically. It is highly accessible for anyone with a hearing impairment, hyperacusis (sound sensitivity) or deaf users.

Input and touch

The nebulizer is reasonably accessible, but does require some precision to assemble for use. It has multiple small components to line up and fit, however they slot in easily with no force or rotation needed. Once assembled, it is turned on by holding the single button on the device for a couple of seconds. Due to the mechanism involved it can’t be tilted or shaken. I would highly recommend placing it on a flat surface whilst in use and extending the mask with the included tubing to fit comfortably in that position.

Ease of Use

Set-up and use is relatively easy with instructions provided. The instructions are written in very bad english, but they are simple enough and accompanied by illustrations. It boils down to sterilize parts prior to use, add water to the water vessel, add medication liquid in the medicine cup, place cup into/over the water vessel, cover with lid, attach mask to lid, hold button to turn on and use.

Maintenance is easy. Pour the remaining water out, wipe the container, sterilise the cup, mask and mouthpiece, dry all parts and story in a dry and ventilated place after use. Don’t forget to keep the batteries charged.

The Excelvan ultrasonic nebulizer is portable, quiet and efficient. It took about 5 minutes to dispense a full dose of medication. My standard nebulizer takes 20 minutes. It is very light, packs away easily for travel and as long as I carry my medication and a small bottle of water, I can use it anywhere. It is also affordably priced and one of the cheapest battery operated portable nebulizers on the market.

The main disadvantages are obvious. It is a usable piece of equipment that has worked fine, but as it is a generic model and not manufactured by one of the top brands in the industry and as it does not come with a warranty, I personally would feel safer having a back-up in place, which I do. Ultrasonic nebulizers generate heat of up to 30 degrees, making it unsuitable for a range of nebulized medications. It also has to remain in an upright position whilst in use.

The Excelvan ultrasonic nebulizer has worked well for me, but I would pay more for a VMT nebulizer made by a top brand if I required a nebulizer for daily use. I would recommend the Excelvan ultrasonic portable nebulizer for occasional to regular use if your care provider endorses it for your particular case and medication(s). It is great value for money, simplistic and does exactly what it is supposed to do.
