Cleaning the World’s Air and Water
With 7 million annual deaths from air pollution (WHO), polyester felt filtration media is scaling to meet global demand. Siemens’ latest power plants achieve 99.999% particulate capture using nano-fiber enhanced felt.

Technical Breakthroughs

• Efficiency Metrics:
  • MERV 16 rating for 0.3-1.0µm particles (ASHRAE 52.2)
  • 98% oil/water separation efficiency (API 811)
• Durability:
  • 50,000+ operating hours in 300°C flue gas
  • Chemical resistance to pH 1-14 (ASTM D543)

Case Study: Tesla Gigafactory Air Purification
Tesla’s Nevada facility deploys:

• 10,000m² of felt filter walls capturing lithium dust
