Abstract: An air cleaner and an oil mist filter are disclosed. The air cleaner includes a main body, and a filter device. The filter device includes at least one dust filter configured to filter external air and an oil mist filter configured to filter oil mist. The oil mist filter includes a stationary filter including a plurality of first baffles, and a movable filter including a plurality of second baffles respectively corresponding to the plurality of first baffles. The movable filter is movably disposed on one side of the stationary filter to be moved to first or second position. The oil mist filter is provided with a first air path in the first position, the first and second baffles are positioned closest to each other. The oil mist filter is provided with a second air path in the second position, the first and second baffles are farthest away from each other.

Abstract: Disclosed are an electronic device for food management and a control method thereof. A control method of an electronic device for food management includes measuring intensity of light, which is irradiated with food and reflected, by wavelengths using an infrared sensor; obtaining state information of the food based on the measured light intensity information; and adjusting at least one of temperature and humidity of an area where the food is disposed in the electronic device based on at least one of the obtained state information and preset usage plan information of the food. Accordingly, food which is managed in an optimal sate in consideration of a state of a food stored in an electronic device and a using method (consumption period and consumption method) of the food can be provided to a user.
