A device includes a housing including an inlet and an outlet, the inlet being configured to intake an infectious agents contaminated air, and the outlet being configured to output a sterilized air. The device also includes a superheating heat exchanger configured to increase a temperature of the infectious agents contaminated air by superheating the contaminated air, the infectious agents contaminated air becoming the sterilized air after being superheated. The device further includes a cooling heat exchanger configured to cool down the sterilized air and direct the sterilized air to the outlet of the housing.

A essential oil diffuser that gasifies a liquid, such as water, which passes through a screen where it picks up essential oil and diffuses it into the ambient air.

The present invention relates to a radiation-resistant microporous membrane having a hydrophobicity gradient, to a method for the preparation thereof, and to the use of the membrane in the sterilizing filtration of gaseous fluids or as a liquid barrier in liquid-containing systems to be vented.

A nasal-plug filter device including a device body, a filter, a first actuator, a second actuator, and a gas sensor is provided. The device body has a ventilating channel, and the ventilating channel has an inlet end and an outlet end. The filter is disposed at the outlet end. The first actuator is disposed at the inlet end for being driven to transmit gas outside the device body into the device body. The second actuator is stacked on and bonded to the first actuator, and the second actuator is driven to transmit the gas transmitted by the first actuator to the filter to be filtered and purified. The gas sensor is disposed at the outlet end. A connection element may be provided for connecting two nasal-plug filter devices with each other.
