Purifier P1 gives users an air-management option when outdoor ventilation is not practical.
The design challenge was not only the purifier itself, but the maintenance experience
around it: how users understand filter life, replace the cartridge, and trust the system over time.
My role was to make that experience clear, reliable, and visually consistent with the E1 ecosystem.
Form Defined by Performance
The purifier’s final form was the result of nearly a year of testing and system-level trade-offs. Filtration efficiency, filter lifespan, airflow performance,
and overall size were evaluated together to ensure the product matched E1’s actual printing conditions without becoming unnecessarily large.
