Physicist creates cotton candy respirators: it’s cheaper and faster

Mahesh Bundy, a physicist in the Department of Nonlinear and Non-Equilibrium Physics at OIST Alumni University, has found a way to make Type 95 Respiratory Filters cheaper and faster.

Research has shown that to prevent infection. People need to wear a # 95 respirator, a face mask with filters that traps viruses while preventing them from passing through. These respirators are more expensive and more difficult to manufacture.

Mahesh Bundy has found a way to make the filter as effective as the one used in the # 95 respirator but requires less effort and resources to manufacture.

To do this, you need to heat the plastic, which, for example, is used in the production of bottles or bags, after which the mass must be placed in a machine for the production of cotton candy. It turns the plastic into a cotton candy-like material and charges it as it rotates. You need to cut the resulting material into small squares and then place them next to the ventilation hole of a conventional air ionizer to increase their electrostatic charge.

Bundy put the finished filters inside the surgical masks and found that they worked very well, but the mask did not fit. After that, Bundy designed his own mask, making it easy to insert and remove filters (three are required for each mask). The mask was printed on a 3-D printer.

Extensive testing, particularly under a microscope, has shown that the filters are effective against SARS-CoV-2 as standard Type 95 respirators.
