LUX is a car air purifier and on-the-go air monitor, that looks to combat in-car air pollution, a growing health concern around the world.
The aim is to provide a cleaner and healthier environment inside the vehicle, whilst educating and informing the user's about their exposure to air pollution whilst on-the-go.
The air filtration technology within LUX is called Photocatalytic Oxidisation (PCO). Photocatalytic Oxidisation is a technique that was originally used in meat processing plants and fruit and vegetables industry to remove bacteria and pesticides. It isn’t implemented into any car purifiers on the market as it has only been recently introduced into consumer products.
LUX neatly fits into the cars cup holder and is powered by the 12V power supply using a USB-C power cables.
The base of LUX is removable which allows the user to access the PCO module located inside the main body. The module needs to be removable as the catalytic mesh has a life of one year. The module is secured into the main body with a 1 pin DC magnetic power connector, which aids in removing and relocating the module after the mesh has been replaced. The base utilises a 3 stop screw thread, resulting in minimal effort to remove it.
The PCO module is made up of 3 main components, a UVC bulb, DC axial fan and a catalytic mesh. The catalytic mesh is coated with titanium dioxide (TiO2). The UVC bulb activates the catalyst on the mesh (TiO2).
This causes it to release free radicals, which attach themselves to the pollutants and break them down into their simplest form, carbon dioxide and water, but at such microscopic levels that they simply evaporate into the air. The outcome of this process is that pollutants within the air are removed, leaving a healthier and cleaner air environment.
what's the point?
Initial sketches were used to explore forms and interactive elements. The design was refined and evaluated with the users to get to the best all-around solution.
Internals components were specified and integrated into a detailed CAD model. Additionally, a functional prototype was created that consisted of a Grove Dust sensor (PM2.5 and PM10), multi-channel gas sensor (Carbon Monoxide and Nitrogen Dioxide) and VOC sensor.
3D prints were created and component were outsourced for machining, with ultimate goal of creating a fully aesthetic prototype for testing.
