IIT-Madras gives India its first home-grown, remote-controlled 'affordable' air-purifier

IIT Madras' startup develops 'affordable' air purifier

To tackle indoor air pollution, AirOK Technologies, a startup incubated by IIT Madras, has developed 'Vistar', a 'smart' air-purifier, which can be remotely monitored through a mobile phone.

Vistar will have futuristic features like Wi-Fi and touch interface.

It would cost Rs. 20,000 and last for a year, which is twice the longevity of the air purifiers currently available in the market, said researchers.

The device having metallic silver body and cylindrical shape comes in two models: Vistar 450 and Vistar 550, depending on the coverage area measured in square feet.

While the smaller model weighs 8kgs, the other one will be of 9.5kgs.

Both the air purifiers will measure 300mm in diameter and 520mm in height, said Deekshith Vara Prasad, Founder and CEO, AirOK.

Function

Has the ability to filter particulates up to 0.3 microns

Vistar has the ability to filter particulates up to 0.3 microns, including volatile organic compounds (which contributes to ozone formation), acidic and basic pollutants (such as sulfur dioxide and nitrogen oxides), airborne bacteria and pet dander (very tiny particles of skin that are shed by animals with fur or feathers).

It would run on AirOK's patented filter technology, Efficient Granular Absorbent Particulate Arrester (EGAPA).
