[0003] Increasing industrialization and construction activities are essential for the economic development of a region. But at the same time, these activities make the environment air polluted. Such polluted air contains a high concentration of very minute particulate matter such as Sculpture, Carbon in very small sizes for example at 2.5 pm. Inhaling such air can cause many respiratory diseases in a healthy person and aggravate the condition of persons already affected by obstructive pulmonary diseases.
[0004] Therefore, air purification devices are becoming increasingly popular and such portable devices are present in the market with different functions for purifying air. These devices are very effective in small and closed rooms for homes and offices. The air purifier cleans contaminated air present in the room or other enclosed environments and dust reduction, haze removal, and removes harmful chemical and particulate residues from the room to improve the living conditions and office conditions that promote the physical and mental health of the user.
[0005] However, the majority of the available air purifiers in the market are static and to be plugged into a socket in the designated room to operate and clean the air. In case, a single device is available in the home/office and the user wants to use it in another room then the device needs to unplug from one room and plug into another room. As there are "n" rooms that must be purified separately, with “n” different purifiers, the cost of air purification for a residence or office also increases significantly..
[0006] There is, therefore, a need to overcome the above drawback, limitations, and shortcomings associated with the existing methods for purifying air using air purifiers and provide simple, fast, and cost-effictive air purification device that can be controlled remotely in a wireless network.

[0047] In an embodiment, processing controls and other operational functions associated with the plurality of sensors 114 are performed by the microprocessors. Memory, such as RAM, Flash programmable read-only memory, and other associated digital functions, the action of starting and stopping, self-diagnostic or pre-set changes for device 100 are also aided with the microcontroller 212.
[0048] In an embodiment, the required communication for the command from the user is activated through Wi-Fi part of the board that provides compatibility with Wi-Fi and Bluetooth connectivity with one or more pairing articles. The pairing articles may be a remote unit or a smart mobile. The Wi-Fi module is a self-contained system-on-chip (SoC) with an integrated TCP/IP protocol that provides access.
[0049] In an embodiment, when gas monitoring sensor 114-A monitors the presence of harmful gases like CO, CO2, SO2 gases, and an optical sensor 114-B that count and monitor particulate matter present in the air using a source of laser light 208 detects the quality of the air present in the room and transmit a signal to control unit 110. The control unit 112 transmits a command to start the operation of air purifying by switching on the blower motor 106. Device 100 starts receiving air from inlet 132 to filter the received air by air filter unit 104. The filtered air is emitted out from outlet 134 which is configured with housing 102 opposite to inlet 132.
[0050] In an embodiment, once the level of the air quality comes down to the pre-determined level, the harmful gases mixed in the air are purified to make it safe for breathing, the device 100 moves from the operating room to the next room as per the programmed path. The speed of blower motor 106 is also changing automatically as per the programming taking into consideration of the air quality index.
