Public Transport Infrastructure

Why Filtration Matters

Public transport systems, such as metro stations, buses, and airports, require high-efficiency air filtration to reduce airborne pollutants, fine dust, and allergens. Our HVAC HEPA filter materials and high-efficiency particulate air filter media help enhance indoor air quality in public transportation hubs. Designed for use in train ventilation systems, subway station air purifiers, and airport HVAC filtration, our solutions contribute to passenger comfort and health.
Why Filtration Matters

Industry Challenges

Dust Accumulation

Clogging HVAC systems in underground stations

Fire Compliance

Meeting DIN 5510/NFPA 130 smoke toxicity limits

Corrosion Risks

Moisture & chemical exposure in tunnels

The Hidden Threats in Public Transport Infrastructure

Underground Air Crisis

  • PM2.5 Avalanche: Subway air contains 6x more fine dust than street level – equivalent to passively smoking 2 cigarettes per 30-minute commute.
  • CO₂ Drowsiness: During rush hours, platform CO₂ levels reach 2,500ppm (like 150 people breathing in a sealed minivan).
  • Viral Highways: Recirculated air spreads 58% more respiratory viruses (comparable to sharing a mask with 10 strangers).

Outdated Solutions

  • Primitive Filters: 80% stations use fiberglass filters missing 70% of PM1 particles (like stopping rocks but missing sand).
  • Oversized Fan Paradox: Running 500HP fans costs $3.2M annually – enough to electrify 80 buses for 10 years.
  • Chemical Fog Risks: Disinfectant sprays increase asthma ER visits by 22% among staff.
