Initial Phase
Draft 1
Our very first prototype was designed for non-smoking neighbours who were heavily disturbed by second-hand smoke which drifted in through windows. It consisted of a small filtration device that will ideally sit on the ledge of a window, as well as a windshield that covers the whole window. Our aim was to purify atmospheric air, before releasing odour-less and toxin-free air into the house. However, upon discussion, several issues were raised.
- Difficulties in attaching our filtration device to all types of windows, and safety concerns that may arise from attachment failures.
- The feasibility of sealing all windows air-tight.
- The efficiency of such a small filtration device
Draft 2
Our next draft looked similar to a standing air purifier, with the addition of a suction pipe that ideally directs all smoke into through the filtration system. We will also consider the type of filters that should be used.
Draft 3
Changes made from the previous draft include
- Fans will be placed as the last unit to direct air flow through the filters.
- 4 small fans will be used in replacement of 1 large fan, due to cost constraints.
- Tubes be printed to connect air flow between the filters and fans.
- Flat filters will be adopted for this project given their versatility.
- A cuboidal body will be used to accommodate to the shape of our filters.
Prototype
Our prototype will consist of 6 fans, 1 HEPA filter, 2 Carbon filters and 1 Zeolite filter.
