AB  - A bimodal web, where both nanofibers and microfibers are present and distributed 
      randomly across the same web, can deliver high filter efficiency and low pressure 
      drop at the same time since in such a web, filter efficiency is high thanks to 
      small pores created by the presence of nanofibers and the interfiber space 
      created by the presence of microfibers, which is large enough for air to flow 
      through with little resistance. In this work, a bimodal polyamide 6 (PA6) filter 
      web was fabricated via a modified solution blowing (m-SB) technique that produced 
      nanofibers and microfibers simultaneously. Scanning electron microscope (SEM) 
      images of the webs were used to analyze the fiber morphology. Additionally, air 
      permeability, solidity, porosity, filtration performance, and tensile strength of 
      the samples were measured. The bimodal filter web consisted of nanofibers and 
      microfibers with average diameters of 81.5 +/- 127 nm and 1.6 +/- 0.458 mum, 
      respectively. Its filter efficiency, pressure drop at 95 L min(-1), and tensile 
      strength were 98.891%, 168 Pa, and 0.1 MPa, respectively. Its quality factor (QF) 
      and tensile strength were 0.0268 Pa(-1) and 0.1 MPa, respectively. When compared 
      with commercially available filters, the bimodal web produced had superior filter 
      performance, constituting a suitable alternative for air filter applications.
