11 things to know before buying a nebulizer for home use

3. Ultrasonic nebulizers — speed with caveats

Ultrasonic nebulizers create aerosol by using high-frequency vibrations to agitate the liquid. This method can deliver medication quickly and with a fine particle size, which has appeal when shorter treatment times matter. But there’s a major caveat: ultrasonic devices generate heat during operation, and that can change the properties of some medications, especially suspensions and heat-sensitive formulations. Because of this, ultrasonic nebulizers aren’t the best choice for every prescription. They still have a role for saline-based therapies and some bronchodilators, particularly when quick output and quiet operation are priorities. Maintenance is generally simple, but users must follow cleaning instructions closely to avoid mineral buildup and to protect the vibrating diaphragm. If you’re considering an ultrasonic model, confirm with your prescriber or pharmacist that your medication is safe to use in that technology. For home shoppers who value speed and quiet and who use pharmacist-approved solutions, ultrasonic units can be handy—but they’re not as universally compatible as compressors.
