Compact CR is a structural and functional reimagination of the original Corsi-Rosenthal box purifier — one that asks whether clean air can be made more accessible by making the device that delivers it smaller, cheaper, and easier to build.

The work treats the original design as a starting point, not a ceiling. A MERV-13 filter at the back, a computer fan at the front, and a compressed 15.6 × 15.6 cm frame — airflow passes through the filter and is pushed outward by the fan's pressure, maintaining the original's far-reaching purification capacity at a fraction of its footprint.

The process moved from pattern to prototype. A laser-cut wooden base established the dimensions and tested structural logic before committing to material. Once the geometry held, the model was translated into a durable 3D-printed form — one capable of long-term use and real-world conditions. The shift from concept to physical object was where the design was tested, not just described.

Technical Stack:

• Physical fabrication: Photoshop (pattern mapping), laser cutting, 3D printing (durable filament)

• Dimensional design: Custom frame engineered to MERV-13 filter and computer fan specifications

• Hardware: MERV-13 particulate filter, box fan, compact enclosure
