Ultrasonic Humidifiers Vs. Electric Humidifiers

There are many types of humidifiers on the market and each has its pros and cons depending on the application. Ultrasonic and electric type humidifers are no exception and it is important to know the distinctions between the two to ensure maximum performance of the installation. Here is a table showcasing a brief overview of the main differences between those two types and the advantages of electric over ultrasonic humidifiers.

Ultrasonic versus SK300 Neptronic electric steam humidifiers

Items Ultrasonic Neptronic
Operation Adiabatic humidification systems use mechanical energy to generate water particles. (Ultrasonic – piezoelectric transducer) Isothermal humidification systems use electricity as an external heat source to change water to steam. (Electric resistance)
Generated Steam The ultrasonic generates a cold mist which is the reason why the power consumption is low. Neptronic humidifiers boil the water inside an evaporation chamber to generate clean steam.
Water Types This type of humidifier requires a RO water filtration system to supply clean water to the humidifier.
It cannot be supplied with tap water.
The minerals from the water will be carried into the airstream and will appear as dust.
It can be used with tap, RO or DI water.
Neptronic humidifiers have a stainless steel cleanable evaporation chamber which can be easily be removed for maintenance.
Winter Season Operation If humidification is required during the winter seasons then the cooling of the air temperature must be considered in the heating load calculation as ultrasonic humidifiers provide a cooling effect. Neptronic humidifiers provided hot clean steam which could add a small heat gain during heating season
Output capacityFor large output, it will require multiple unitsNeptronic humidifiers have a wide range of models from 6 to 270 lb/hr with a single unit.
Hygienic Operation Since the water is not boiled to produce a mist, there is a risk of bacteria present in the mist and being discharged into the room. Disinfecting the humidifier becomes even more important than with a humidifier that boils the water.Neptronic electric humidifiers generate clean hot steam because they boil the water inside the evaporation chamber.
