Form
A simple cylindrical body gives the product a planter silhouette and makes placement less awkward.
An air purifier concept built around a small annoyance: most air purifiers look like appliances first and part of a home second.

Can clean-air hardware stay visible and useful without making the room feel more mechanical?
Hide the purifier inside the familiar visual language of a terracotta planter. The object reads as part of the room first, then reveals the function through airflow, controls and maintenance access.
A simple cylindrical body gives the product a planter silhouette and makes placement less awkward.
The concept uses replaceable HEPA + activated carbon filtration instead of inventing a proprietary consumable for no good reason.
Terracotta-coloured ABS keeps the material practical while borrowing the warmth of a real planter rather than copying literal clay.
Airflow and acoustics before aesthetics. I’d test intake area, exhaust direction, fan noise, filter access and whether the plant element hurts performance or just looks nice in renders.
Disguising the product too well. If maintenance, controls or airflow become worse because the purifier is trying too hard to look like decor, the concept fails its actual job.
Whether people genuinely dislike the look of existing purifiers enough for this form factor to matter. Then whether they still trust an air purifier that does not visually announce “I am a machine”.
It is a reminder that product design is not always about adding a feature. Sometimes the useful move is changing how an object belongs in a space.
