Introduction

Nanofiber filters are a revolutionary technology that plays a vital role in various applications, with a significant impact on air purification systems. These filters are designed to remove particulate matter and pollutants from the air, ensuring that the air we breathe is clean and safe.

What is a Nanofiber Filter?

A nanofiber filter is a type of air filtration technology that utilizes nanoscale fibers to capture and remove particles from the air. These filters are designed to be highly efficient at trapping a wide range of contaminants, including dust, allergens, bacteria, viruses, and even ultrafine particles such as PM2.5 and PM0.1. Nanofiber filters are used in various applications, from air purifiers and HVAC systems to protective masks and industrial filtration.

Nanofiber Filters

How does nanofiber work?

Nanofiber filters work through a combination of mechanical and electrostatic filtration mechanisms. The extremely small diameter of the nanofibers, typically in the range of 100-500 nanometers, creates a dense web of fibers with a high surface area. When air passes through the filter, several processes come into play:

  • Mechanical Filtration: The fine nanofibers physically block and trap larger particles as they pass through the filter. The intricate network of nanofibers creates a labyrinthine path for air, which increases the chances of particle interception.
  • Electrostatic Attraction: Nanofibers often carry an electrostatic charge due to the manufacturing process. This charge can attract particles with opposite charges, enhancing filtration efficiency. Electrostatic attraction is particularly effective for capturing smaller particles and even some viruses.
  • Diffusion: For ultrafine particles, Brownian motion causes them to collide with nanofibers, leading to their capture.

The combination of these mechanisms makes Nano Fiber Filters highly efficient in removing contaminants from the air, offering superior filtration performance compared to traditional filter materials.
