Context - showing the Refresh Filter in context.
Research - the research which backed up and shaped the final outcome.
How it works - The filter also houses the power input, this means the product can't be switched on without the filter in, so no one can jam a pencil into the spinning fan. The design incorporates a cradle to cradle method of thinking, instead of throwing the filter away with the valuable conductive centre coil, they can be returned to the shop and topped up - similar to an ink cartridge.
Off - The cork trim is meant to symbolise its intentions, natural and pure. whereas the ceramic body is quite sterile and unnatural. The red threaded cable is a personal opinion, why should we hide the life line to our products? why not make them a feature?
good air quality - The product starting to sense the air quality around it, the more its open, the worse the air quality.
bad air quality - The filter also house neutral relaxing scents which are proven to increase productivity in a work space. This shot shows the product working at full speed.
Model - This is a Rapid prototype, the cork trim might be the most awkward thing i've ever done. It does raise questions for manufacture.
