Burean - Fan Purifier

At a glance

The challenge
An existing fan-attachable air purifier was hard to install and did not filter air effectively enough.
Who it’s for
College students in residence halls and apartments, in rooms up to 150 sq ft.
What I did
A problem → ideation → conceptualisation process, sketching and rendering how the purifier attaches to the fan and how air moves through it.
Outcome
A 7-part purifier that latches onto an existing fan and uses its oscillation to purify air, trading some manufacturability for a design that suits a student’s room.

Skills used

  • Problem framing
  • Product redesign
  • Sketching
  • CAD & rendering
  • Design for manufacture

The project aims to redesign a fan-attachable air purifier that already exists. The main goal is to fix the installation issue the users are experiencing with the current product and to enhance its performance so that it can filter the air more effectively. The intended market for this product is college students who live in residence halls or apartments. The air purifier is made to fit the needs of spaces up to 150 square feet in size.

Ideation and Initial Concepts

I followed a problem, ideation and conceptualization process, exploring how the purifier could latch onto an existing fan and use the fan’s own oscillation to move air through the filter.

Final Concept

The final concept makes the model harder to manufacture, but the design suits a student’s room and the brief, and consists of 7 parts in total.
