Description:BACKGROUND
Field of Invention
[001] Embodiments of the present invention generally relate to an air purifier and particularly to a transparent air-purifying film for application on a window.
Description of Related Art
[002] Air quality concerns have gained significant attention due to rising levels of pollutants in urban and industrial areas. Various sources contribute to indoor and outdoor contamination, including vehicular emissions, industrial discharges, and household activities. Particulate matter, volatile organic compounds, and microbial contaminants present health risks, particularly for vulnerable populations.
[003] Conventional air purification systems employ filtration technologies such as high-efficiency particulate air (HEPA) filters, activated carbon layers, and electrostatic precipitators. While effective in trapping airborne impurities, these solutions involve constraints related to energy consumption, periodic replacement of filter media, and limited adaptability for compact spaces. Additionally, existing filtration mechanisms often function as standalone units that require dedicated installation space.
[004] There are further window glass coatings that have been developed to address certain environmental concerns, particularly in regulating heat and ultraviolet (UV) radiation. These coatings, often made of metal oxides, nanostructured materials, or polymer-based compounds, provide thermal insulation, reduce glare, and enhance energy efficiency by minimizing heat transfer. Low-emissivity (Low-E) coatings, for example, help in controlling infrared radiation, while UV-blocking coatings prevent harmful ultraviolet exposure. Despite these benefits, existing coatings primarily focus on solar control and energy efficiency rather than providing solutions for air pollution.
[005] Continuous efforts have been made to mitigate air pollution-related issues through filtration systems, ventilation improvements, and chemical treatments, but existing solutions often require external power sources along with frequent maintenance. Additionally, a sizing factor prevents installation in smaller living spaces or vehicles.
[006] There is thus a need for an improved solution that can administer the aforementioned limitations in a more efficient manner.

[0029] In an embodiment of the present invention, the film 100 may be adapted to be applied on glass substrates that may be arranged on an opening of the window. In another embodiment of the present invention, the film 100 may be adapted to be applied on non-glass substrates such as, but not limited to, nets, mesh screens, fabrics, curtains, polymer sheets, acrylic panels, polycarbonate sheets, air channels, and so forth. After application, the film 100 may purify an indoor air of an interior space corresponding to the window.

[0034] According to the embodiments of the present invention, the film 100 may incorporate non-limiting hardware components to enhance the processing speed and efficiency such as the film 100 may comprise functional layers such as, an electrostatic nanofiber layer 102, an activated carbon layer 104, a photocatalytic oxidation layer 106, a self-cleaning hydrophobic coating 108, an adhesive layer 110, a sensor unit 112, and a processing unit 114. In an embodiment of the present invention, the hardware components of the film 100 may be integrated with computer-executable instructions for overcoming the challenges and the limitations of the existing transparent air-purifying films.
[0035] In an embodiment of the present invention, the electrostatic nanofiber layer 102 may be adapted to refrain passing of airborne particulate matter of air from an exterior of the window to an interior space.

However, the life span of the electrostatic nanofiber layer 102 may tend to decrease in cases when higher amount of the airborne particulate matter may be blocked by the electrostatic nanofiber layer 102. Furthermore, the electrostatic nanofiber layer 102 may feature a self-clean mechanism. The self-clean mechanism may clean the electrostatic nanofiber layer 102 without any human intervention.
[0037] In an embodiment of the present invention, the activated carbon layer 104 may be adapted to adsorb volatile organic compounds (VOCs), harmful gases, odours, and so forth.

[0038] In an embodiment of the present invention, the activated carbon layer 104 may have a life span ranging between 3 years to 5 years. However, the life span of the activated carbon layer 104 may tend to decrease in cases when higher amount of the volatile organic compounds (VOCs), the harmful gases, the odours may be absorbed by the activated carbon layer 104. Furthermore, the activated carbon layer 104 may feature a self-clean mechanism. The self-clean mechanism may clean the activated carbon layer 104 without any human intervention.
[0039] In an embodiment of the present invention, the photocatalytic oxidation layer 106 may be adapted to neutralize bacteria, viruses, and organic pollutants under Ultraviolet (UV) light. The photocatalytic oxidation layer 106 may comprise a titanium dioxide (TiO₂) coating. In an embodiment of the present invention, the photocatalytic oxidation layer 106 may have a life span ranging between 3 years to 5 years. However, the life span of the photocatalytic oxidation layer 106 may tend to decrease in cases when higher amount of the bacteria, viruses, and organic pollutants may be neutralized by the photocatalytic oxidation layer 106. Furthermore, the photocatalytic oxidation layer 106 may feature a self-clean mechanism. The self-clean mechanism may clean the photocatalytic oxidation layer 106 without any human intervention.
[0040] In an embodiment of the present invention, the film 100 may be structured with a defined layering sequence of the functional layers. For instance, the self-cleaning hydrophobic coating 108 may be an outermost layer facing the exterior of the window, adapted to repel dust, dirt, and water, thereby preventing surface contamination and minimizing maintenance requirements. Beneath this, the photocatalytic oxidation layer 106 may be positioned to facilitate the decomposition of bacteria, viruses, and organic pollutants under ultraviolet (UV) light. Further inward, the electrostatic nanofiber layer 102 may be arranged to capture the airborne particulate matter. Below the electrostatic nanofiber layer 102, the activated carbon layer 104 may be arranged that may be adapted to function as a gaseous pollutant filter.
[0041] In an embodiment of the present invention, the adhesive layer 110 may be an innermost layer that may be adapted to enable an adhering of the film 100 directly to a surface of the window. The adhesive layer 110 may be configured to securely attach the film 100 to the window without a need for external fasteners, according to an embodiment of the present invention.
[0042] In an embodiment of the present invention, a total thickness of the film 100 may range between 500 micrometers (µm) and 1.5 millimeters (mm) for balancing air purification efficiency with compatibility for different window applications.
[0043] In an embodiment of the present invention, the film 100 may be particularly suited for curtain-type windows, which allow partial air permeability while maintaining visibility. To accommodate airflow, the film may incorporate micro-perforations or breathable sections, enabling passive ventilation while ensuring pollutants are effectively filtered. The electrostatic nanofiber layer 102 and activated carbon layer 104 may be structured to allow controlled air passage, preventing obstruction while enhancing filtration efficiency. This arrangement may ensure that fresh air circulates through the window while reducing the infiltration of harmful contaminants. Additionally, the film 100 may be designed for durability across various environmental conditions, including high humidity and temperature fluctuations, ensuring long-term functionality without degradation.
[0044] In an embodiment of the present invention, the film 100 may be designed to interact with airflow dynamically, ensuring efficient purification upon contact. When air passes over or through the surface of the applied transparent air-purifying film 100, the airborne pollutants such as the particulate matter, the volatile organic compounds (VOCs), and the harmful gases may be captured and neutralized by the functional layers of the film. The electrostatic nanofiber layer 102 may attract and trap fine particles, while the activated carbon layer 104 may adsorb gaseous pollutants and odors. Additionally, the photocatalytic oxidation layer 106, when exposed to ultraviolet (UV) light, may facilitate the breakdown of organic contaminants, bacteria, and viruses for enhancing air purification effectiveness.
[0045] In an embodiment of the present invention, depending on the substrate material and permeability, the film 100 may either allow controlled air passage through micro-perforations or function as a surface-based filtration medium. On solid glass substrates, the film 100 may purify air as the air moves across the surface by neutralizing contaminants upon contact with the film 100. On breathable surfaces, such as the mesh screens, the air channels, or the fabric-based curtains, the film 100 may enable passive airflow while ensuring that the air pollutants are effectively captured before entering the interior space. This adaptive functionality may allow the film 100 to enhance air quality in both enclosed and ventilated environments without obstructing visibility or airflow.
[0046] In an embodiment of the present invention, the sensor unit 112 may be integrated in proximity to the window. In a preferred embodiment of the present invention, the sensor unit 112 may comprise micro-sensing chip that may be arranged onto the film 100. This integration may allow the sensor unit 112 to perform an active monitoring of air quality and pollutant levels while working in conjunction with the functional layers of the film 100.
[0047] The sensor unit 112 may be configured to detect air parameters of the interior space. The sensor unit 112 may comprise sensors such as, but not limited to, a particulate matter sensor, a volatile organic compound (VOC) sensor, a carbon dioxide (CO₂) sensor, a temperature sensor, a humidity sensor, and so forth.

Further, the sensor encapsulated in the sensor unit 112 may be Internet of Things (IoT) enabled.
[0048] In an embodiment of the present invention, the sensor unit 112 may be powered using a power delivery source (not shown). The power delivery source may be, but not limited to, rechargeable batteries, solar power, and so forth. Embodiments of the present invention are intended to include or otherwise cover any type of the power delivery source, including known, related art, and/or later developed technologies, that may power the sensor unit 112.
