Toxic Air in India Highlights the Urgent Need for Advanced Air Filtration — How Nanofiltech Helps Protect Indoor Environments
India is once again facing alarming levels of air pollution, with its capital Delhi recording dangerously high concentrations of PM2.5 and a surge in respiratory illnesses. According to a recent BBC report, more than 200,000 acute respiratory illness cases were documented across six major state-run hospitals between 2022 and 2024—evidence of the severe public-health impact of prolonged exposure to toxic air.
In Delhi, winter pollution has become a recurring crisis. Vehicle emissions, industrial output, crop-burning and stagnant weather conditions combine to push the Air Quality Index (AQI) to more than 20 times the WHO recommended limit. During several periods each year, the city’s AQI exceeds 400 (“severe” level), a threshold that can harm even healthy individuals and poses extreme danger to children, the elderly and those with existing lung diseases.
The BBC report also noted that hospitals are seeing an influx of children affected by toxic air, and India’s high courts are repeatedly urging authorities to implement stricter measures to curb hazardous pollution levels.
The Hidden Reality: Indoor Air Is Not Safer Without Proper Filtration
Many businesses and households assume that staying indoors offers protection—yet in polluted cities, indoor environments can accumulate PM2.5 just as quickly if ventilation and filtration are inadequate.
This is where high-efficiency, low-resistance air filtration systems become essential.
Nanofiltech: High-Performance Nanofiber Air Filtration for PM2.5, PM0.3 and Hazardous Aerosols
At Nanofiltech, we develop and manufacture next-generation nanofiber air filtration materials designed to capture the most dangerous particles—especially the PM0.1–PM0.3 range, which can penetrate deep into the lungs and bloodstream.
Our advanced filtration solutions are already used globally across HVAC systems, hospitals, cleanrooms, semiconductor plants, commercial buildings, industrial ventilation, and high-dust manufacturing sites.
Why Nanofiltech Nanofiber Filters Matter in High-Pollution Regions Like India
Ø Captures ultrafine particles (PM0.1–PM0.3)Nanofiber filter media provide a multi-layered interception structure, greatly improving efficiency against the smallest and most harmful airborne pollutants.
Ø Lower pressure drop → Lower energy consumptionCompared with traditional glass-fiber or melt-blown filters, Nanofiltech nanofiber filters maintain the same or higher filtration efficiency with significantly lower resistance, enabling HVAC systems to operate with 10–30% less energy consumption.
Ø Longer service life in polluted environmentsNanofiber media resist rapid clogging and maintain stable airflow over time—critical for cities where outdoor PM2.5 stays above 150–300 μg/m³ for extended periods.
Ø Stable performance without electrostatic decayUnlike electrostatic melt-blown materials, Nanofiltech nanofibers do not suffer performance drop due to charge loss.
Ø Suitable for high-pollution countries and industrial applicationsIncluding India, Bangladesh, Pakistan, Vietnam, Indonesia, Thailand and Middle-East regions with growing demand for clean air systems.
