A graphene adsorbing material, a preparation method therefor and application thereof, and a cigarette filter tip and a cigarette are provided. The graphene adsorbing material comprises a fiber carrier, graphene and doped elements wherein the graphene and the doped elements are loaded on the fiber carrier and the doped elements comprise at least one of Al, Si and Fe. The graphene adsorbing material is obtained by contacting the fibers with the graphene material to load the graphene material on the fibers. By introducing the graphene and the doped elements in the fiber carrier, harmful substances with a type of fused aromatic hydrocarbons such as benzopyrene in smoke can be specifically adsorbed, filtered and removed; while nicotine and the other harmless substances are retained, and thus the smoking taste of a cigarette is not affected. The cigarette filter tip can effectively adsorb cancerogenic substances with a type of fused aromatic hydrocarbons such as benzopyrene in smoke to reduce harm of smoking; meanwhile, the pleasure of smoking and the mellow taste of the smoke are not affected. Besides, the graphene adsorbing material can also prevent the phenomenon that a cigarette holder gets mildewed due to humid environment and the other factors.

The smokers module comprises a smoking space and an air handling system. The air handling system processes the air within the smoking space. The air handling system further comprises a filter chain, an air exhaust, an air intake, and a plurality of fans. The plurality of fans recirculate the air contained within the smoking space for processing. Specifically, the plurality of fans: 1) pump air through the filter chain; 2) draws fresh air into the smoking space through the air intake; and, 3) discharges air from the smoking space into the atmosphere. The filter chain removes organic compounds, inorganic compounds, and radicals from air drawn from the smoking space. The air intake draws fresh air into the smokers module and the air exhaust discharges air from the smokers module into the atmosphere.

A cascadable air purifier is provided. The cascadable air purifier has a housing unit, a connecting unit, a purifying unit, and a control unit, wherein the connecting unit has at least one male coupling portion and at least one female coupling portion. The cascadable air purifier can be combined with another cascadable air purifier by the male coupling portion and the female coupling portion.

An air purifier capable of reducing time required for purification of a room without giving a feeling of discomfort to a human in the room is provided. During operation of an air purifier 1, air drawn from an inlet 3 into a casing 2 is purified by a purification device 7 and the air is blown to the outside from an outlet 4. If a user of the air purifier 1 selects a particular operation mode in which the user designates an air volume, a control device 12 performs air volume maintaining control. In the air volume maintaining control, with a volume of air blown out from the outlet 4 by the air blowing device 5 maintained constant, a speed of the air is varied by an air guiding device 8 based on a status of pollutant detection. Alternatively, the speed of the air is varied by the air guiding device 8 and the volume of the air is varied by the air blowing device 5. Consequently, a dust removal efficiency can be enhanced without giving a feeling of being blown by air to a human in a room, enabling reduction of time required for purification of the room while maintaining user comfort.
