PureAura Air Purifier is a humanitarian technology designed to improve indoor air quality and safeguard residents’ health in sub-divided units (SDU), a penurious housing option common to lower income families in Hong Kong.

The most distinctive features of the SDU Air Purifier are affordability, portability, high efficiency, compact and easy to assemble, and low power consumption.

The Air Purifier costs less than $15 USD and can operate for 40 hours on a small 10000mAh USB power bank.

The Air Purifier is proven to be effective in reducing the indoor concentration of fine particulate matter (PM 2.5) by 80% to less than 5ug/m3, meeting the recommendation under the World Health Organization Global Air Quality Guidelines.
