Background:

The COVID-19 pandemic caused a critical shortage of N95 filtering facepiece respirators (FRs).
Effective filtration layers are essential for N95 FR performance against SARS-CoV-2.
Limited access to specialized manufacturing hinders N95 respirator availability.

Purpose of the Study:

To present practical design principles for fabricating electrocharged filtration layers for N95 FRs.
To enable the use of commonly available materials and replicable methods for N95 filter production.
To address the scarcity of N95 respirators through accessible fabrication techniques.

Main Methods:

Utilized polypropylene or polystyrene, including recycled plastic containers, as input polymers.
Adapted the cotton candy (CC) principle for electrocharged fabric fabrication.
Developed simple design rules for constructing or modifying CC machines for filter production.

Main Results:

Demonstrated the fabrication of electrocharged filtration fabrics using the CC principle.
Provided basic characterization of structural and filtration properties of the fabricated fabrics.
Established design rules for accessible N95 filter layer manufacturing.

Conclusions:

The cotton candy principle offers a viable method for producing electrocharged filtration layers for N95 respirators.
This approach allows for the use of recycled plastics, promoting sustainability.
The developed fabrication principles can enhance N95 respirator availability during global health crises.
