New Murata MHM320

Murata Manufacturing Co., Ltd. has developed the MHM320 ionizer, a new product in the MHM3 DC input series. Mass production began in February 2022. Samples are also available.


The demand for air purifiers has increased in recent years, due to a heightened focus on maintaining health and hygiene. This has resulted in calls to enhance air purifier functionality and to add air improvement functionality to home appliances. In response, Murata has developed a product capable of high-efficient ion generation at low voltage.

This highly reliable and highly safe ionizer module uses Murata’s exclusive high-voltage circuit, insulation technology and generator structure design to efficiently generate ions at lower voltages. The module structure featuring the drive power supply wired to the ion generator provides a high degree of design freedom when incorporating the module into the finished product.

In addition, you can select the model that best matches your application, controlling the amount of ozone generated without changing the volume of ions.
