HEPA stands for High Efficiency Particulate Air (filter)

  • HEPA was a top-secret technology developed during the 1940s by the United States Atomic Energy Commission to efficiently filter radioactive particulate contaminants.  
  • HEPA is a type of highly efficient filtration media that removes microscopic particles from air that passes through the filter.  There are different efficiency ranges depending on particle size.  
  • The most efficient HEPA filter removes 99.7% of particles with a size of 0.3 microns that enter the filter.  
  • Such particles include tobacco smoke, household dust, and pollen.  
  • HEPA filters are most commonly found in household vacuum cleaners and air filters.  
  • Depending on their usage and indoor air quality factors, it is suggested that HEPA filters be replaced every 12 to 18 months.

National Aerospace Laboratories (NAL)

  • NAL is India’s first largest aerospace firm. 
  • It was established by the Council of Scientific and Industrial Research (CSIR) at Delhi in 1959 and its headquarters was later moved to Bangalore in 1960. 
  • The firm closely operates with HAL, DRDO and ISRO and has the prime responsibility of developing civilian aircraft in India. 
  • The CSIR-NAL mandate is to develop aerospace technologies with strong science content, design and build small and medium-sized civil aircraft, and support all national aerospace programmes.
