The air purifier system launched by State-owned Energy Efficiency Services Limited (EESL), a joint venture of Public Sector Undertakings, improves indoor air quality by up to 95 per cent in centrally air conditioned buildings and eliminate traces of pathogens in the air conditioning system, according to the company.
It has applied for final state approval with the Council of Scientific and Industrial Research (CSIR) for certification.
The air purifier system is based on Retrofit of Air conditioning to improve Indoor air quality for Safety and Efficiency (RAISE), a program launched by the Government of India in July 2020. The main objective of the initiative was to improve indoor air quality and facilitate energy savings.
EESL’s air purifier traps pathogens including the novel coronavirus. Asked how does the air purifier trap viruses which are less than 0.3 micron in size, the company said the virus particles ranged between 0.12 to 0.25 micron do not travel autonomously.
“As per scientific reports and data available from studies by WHO, virus particles bind themselves with other aerosols and droplets and travel in the air (with particle size 2-5 micron) which is the cause of human-to-human contagion,” EESL told ETEnergyworld in an interaction.
