Key challenge

Keep it simple, efficient and budget friendly

The goal was to improve the health of families in poverty. They don’t have money nor space to spare. The need for a simple, compact and robust product was real.

01

Good things come in small packages

PureAura offers a straightforward solution that's both efficient and budget-friendly. Priced at less than 15 USD, it operates for 40 hours on a 10,000 mAh USB power bank. Its flat-pack design ensures easy storage and distribution. With the power bank fitting neatly in the back, it's compact and perfect for SDUs. To make it even handier, it's got a handle with a mounting hole and an elastic hanging loop.

02

Easy does it

This air purifier is straightforward to use. Just plug it in, and it runs quietly in the background. The housing is easy to assemble and secured by a simple elastic cord. We intentionally kept it low-tech, so anyone can see and understand how it all fits together, making filter replacements a breeze.

03

Point proven

Lingnan University has proven that the PureAura reduces indoor fine particulate matter (PM 2.5) by a remarkable 80%, achieving levels below the World Health Organization's air quality guidelines at less than 5 µg/m3.

^{"Made from recycled materials, PureAura is compact, energy-efficient, easy to maintain, and highly effective. A strong example of humanitarian technology."} _{A statement by the iF award jury}
