As the country is reeling under the horrific second wave of pandemic and acute oxygen shortage, a start-up in Hyderabad came up with an invention to address the crisis. 'The Phi Factory' has created a portable oxygenator, which works on Hydrogen Peroxide, under the name 'Project Vayuputra'. Vayuputra has been developed with an objective to support COVID-19 patients who are under home isolation. The price of this oxygenator would be around Rs. 2,500 to Rs. 2,600 that includes the oxygenator along with 10x2 liter bottles of Hydrogen Peroxide.
