2. Introduction
• Air pollution is a major concern for public health and the environment.
• Traditional air filtration methods often use non-biodegradable materials that
contribute to environmental pollution.
• Nanofiber offers a sustainable and eco-friendly solution for air filtration.

4. Nanofiber Technologies
• Nanofibers are defined as fibers with diameters on the order of 100 nm.
• Properties; low density, large specific surface area, small pore size, high porosity – good
breathability, excellent mechanical properties.
• Used for;
waste and air purification systems,
batteries,
energy production and storage,
• Nanofibers are produced by nanotechnological methods.

7. Use of Nanofibers in Air Filtration
• Nanofiber helps reduce the
environmental footprint of air filtration by
using sustainable and biodegradable
materials.
• It contributes to a cleaner and healthier
environment by capturing pollutants and
allergens from the air.
