Behind the design

Why was the battery-free aroma diffuser created?

A story born from a single flame.
Design statement A story born from a single flame. The most poetic aroma diffuser in the world—powered by nothing.
A story born from a single flame.

“The flickering of a single candle carries a scent by its breeze” Lei is the world's most poetic aroma diffuser, powered simply by the heat of a candle. Like a fire in ancient times, this home appliance feels indispensable to any social situation—whether to entertain or calm. Made from recyclable materials, Lei generates electricity from the heat of a candle, which in turn creates a gentle breeze that allows volatilized aroma to permeate a space. While sustainable, its minimalist design—featuring cordless mobility and low-maintenance usability—also has great emotional appeal. An entirely self-sufficient product that redefines home appliances.

Works anywhere. Scent, quietly.
Function Works anywhere. Scent, quietly. No cords. Easy care. Anywhere you go.
Works anywhere. Scent, quietly.

Lei’s real advantage is in being a cordless product with minimal maintenance required from the user. It can be transported and used anywhere—by a bedside or bathtub, even outdoors. The essential oils are dropped straight into a tray, making it easy to replenish or clean. The product is also designed to allow users to enjoy the aroma with minimal consumption. While other products tend to overheat oils, Lei uses gentle heat to gradually volatilize the aroma, preserving quality while minimising wastage. It also guarantees safe usage. A sturdy steel platform prevents tipping, and a glass dome protects users from a direct flame.

Three materials. Designed to return to the earth.
Impact Three materials. Designed to return to the earth. Aluminum, rare earths, and glass—entirely recyclable.
Three materials. Designed to return to the earth.

In consideration of the environment, the materials used are limited to three types: aluminum, rare earths, and glass. —all recyclable materials—we ensure that even after the product's life is over, everything, even packaging, can be recycled. Lei embodies the soon-to-be standard values of our post-materialist future, going beyond mere functionality, the user is not just using the product but also enjoying the poetic experience of time and space. Rather than pursuing immediate functionality and convenience, this product embodies the sensitivity to find space in the unseen.
