Definitions

  • the present invention relates to improvements in air purification systems, and more particularly to air purification systems that are adapted to provide purified air into an ambient environment.
  • Air pollution is one of the major problems of urban areas. It is essentially caused due to the introduction of particulates, biological molecules, or other harmful materials into the Earth's atmosphere, leading to detrimental effects on human health. In fact, indoor air pollution and urban air quality are listed as two of the world's worst toxic pollution problems in the 2008 Blacksmith Institute World's Worst Polluted Places.
  • Air pollutants includesolid particles, liquid droplets or gases in an amount which is harmful for living organisms.
  • Air pollutants can be of natural origin or man-made. Airpollutants are classified in two categories; primary pollutants are usually produced from a process, such as ash from a volcanic eruption, carbon monoxide gas from motor vehicle exhaust, or sulfur dioxide released from factories. Secondary pollutants form in the air when primary pollutants react or interact. Some pollutants may be both primary and secondary: they are both emitted directly and formed from other primary pollutants.
  • the in-car pollution is a silent and invisible problem. People tend to believe that inside the car air is free from pollutants and is not harmful, but most air-conditioning systems do virtually nothing to keep the harmful pollutants out.
  • an air purifier having an air inlet for drawing polluted air, an air outlet for dispelling purified air, at least one filter placed in between the air inlet and air outlet, the at least one filter contains activated carbon that purifies the polluted air and a cartridge for adding fragrance to the purified air.
  • FIG. 1 shows an enlarged cross-sectional view of the air purifier in accordance with an embodiment of the present invention.
  • FIG. 1 illustrates anelemental structure of an air purifier used to remove pollutants from indoor air.
  • the air purifier 100 includes a front cover 10, a filter 20, a back cover 30, a bottom cover 40, a cartridge50, a mounting means 60 and a back bottom cover 70.
  • Various covers 10, 30, 40 and 70 are made of plastic or polymer material without limitationacrylonitrile butadiene Styrene, Polycarbonate, Polypropylene and or other materials. One or more of these covers may be perforated or contain slots for exchange of air. Essentially, the front cover 10 acts as an outlet and allows purified air from the filter 100 to flow in an ambient environment.
  • the back cover 30 is placed in close contact with an air source to act as an inlet for the polluted air.
  • the back cover 30 may be placed in front of an AC vent.
  • the filter 20 may be an activated carbon filter with or without an antibacterial layer or an anti-allergic layer.
  • the filter 20 may be formed from one or more of an activated carbon filter foam, sheet granules, liquid, gel, cloth honeycomb, etc.
  • the activated carbon content is 60-100 %.
  • the activated carbon content is coconut shell activated carbon powder.
  • the filter 20 may be a stack of filters selected from one or more of a HEPA filter, a pre-filter, etc.
  • the filter 20 can be treated with titanium oxide in order to provide anti allergen property to the filter 20.
  • a pre-filter captures large particles or particles that are stuck to it. It prevents debris from getting into the activated carbon filter, thereby providing additional strength to filtering.
  • the pre-filter acts as a protective layer for the activated carbon filter 20 which are typically deployed for filtering pollutants of smaller sizes.
  • a pre-filter can be vacuumed, washed, or replaced which helps to prolong the life span of filter 20.
  • a pre-filter may be required to be replaced from time to time.
  • a pre-filter may be a polyester filter, a PP based filter or any other type of particulate filter.
  • a pre-filter can be used to prevent PMio particles from entering into filter 20, thereby increasing efficiency of filtration and reducing damage of the filter 20.
  • a HEPA filter may be used with the activated carbon filter 20 to remove pollutants of size 0.3 ⁇ that may not be filtered by the activated carbon filter 20.
  • a known HEPA filter may be stacked with the activated carbon filter 20.
  • the cartridge 50 may be a container having fragrance mediumfor spreading fragrance inside the ambient environment.
  • the cartridge 50 is placed at the bottom of the purifier 100. However, the cartridge 50 may be placed on top or at the sides of the purifier 100.
  • Fragrance mediums may include, but are not limited to scented oil, liquid, an aqueous solution/emulsion, a solid matrix, gel or the like.
  • the mounting means 60 can be a clip, a hook, a tape or any other mechanism that can be used to fix the purifier 100 to a desired location.
  • means 60 is a clip to hold the purifier 100 on an AC grille.
  • the purifier functions as follows:
  • the present invention is a simple to use and energy efficient system as it does not require any external energy source for its operation.
  • the present invention can be a electricity operated air purifier, with sensors, mobile integrated apps, digital panels, or even battery operated.
