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

Studies have shown that to prevent infection, people need to wear a No. 95 respirator, this is a face

a mask with filters that traps viruses, preventing them from passing through. Such respirators are more expensive and more difficult to produce.

Mahesh Bandi has found a way to make a filter as effective as those used in the No. 95 respirators, but its production requires less effort and resources. 

To do this, you need to heat the plastic, which,For example, it 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 plastic into a material similar to cotton candy, and it is also charged with current when rotated. Then you need to cut the resulting material into small squares, and then place them next to the vent of a conventional air ionizer to increase their electrostatic charge. 

Bundy placed the finished filters insidesurgical masks and found that they work very well, however the mask is not the right size for them. Bundy then designed his own mask, allowing filters to be easily inserted and removed (each mask requires three). The mask was printed on a 3-D printer.

Rigorous testing, particularly under a microscope, has shown that the filters are as effective against SARS-CoV-2 as standard No. 95 respirators.
