Air Filtration


Electrospun nanofiber air filtration applications

Why are nanofibers used in air filtration?

Nanofibers have gained significant attention in the field of air filtration due to their exceptional filtration efficiency and versatility in capturing particles and pollutants. These ultrafine fibers, typically ranging from tens to hundreds of nanometers in diameter, offer several advantages that make them highly effective in air filter applications.

High Surface Area-to-Volume Ratio

Nanofiber applications for barrier materials - high porosity and small pore size

Nanofibers have an exceptionally high surface area, thanks to their small diameter and large surface area-to-volume ratio. This property provides more opportunities for airborne particles to come into contact with the filter media, increasing the overall filtration efficiency.

Submicron Filtration

Nanofiber applications for filtration materials - submicron filtration

Nanofiber filters can effectively capture submicron-sized particles, such as PM2.5 and smaller. Their small fiber size, small pores and high packing density contribute to efficient filtration of these tiny particles, improving air quality and reducing the risk of respiratory health issues.

Enhanced Mechanical Strength

Nanofiber filtration materials - enhanced mechanical strength

Despite their small size, nanofibers can exhibit exceptional mechanical strength and robustness. This property ensures the integrity of the filter media, preventing fiber breakage and maintaining filtration efficiency over time.

Electrostatic Capture

Electrospun nanofiber filter materials - electrostatic capture

Nanofibers can be electrostatically charged, further enhancing their filtration efficiency. Electrostatic attraction helps capture particles with opposite charges, including fine dust, smoke, and other airborne contaminants, leading to improved particle capture rates.

Porosity and Air Permeability

Nanofiber filter materials - porosity and air permeability

Nanofiber filters can be engineered with a controlled porous structure, allowing for efficient air permeability while effectively trapping particles. This property maintains a balance between filtration efficiency and low airflow resistance, optimizing energy efficiency in air filtration systems.

Chemical and Biological Filtration

Nanofiber filters - chemical and biological filtration

Nanofiber filters can be functionalized or coated with specific materials to provide chemical and biological filtration capabilities. These functionalized filters can effectively remove harmful gases, volatile organic compounds (VOCs), and airborne pathogens, enhancing air quality and safety.
