Vojtěch Petráček, Rector of CTU in Prague and a nuclear physicist, shared the simple instructions on how to make a homemade “anti-virus” mask. You only need one PET bottle. The Czech Republic seems to be running low on supplies, so this homemade design may help some people.


  • Two liter plastic bottle.
  • Window sealant (optional).
  • Elastic bands.
  • Paper napkins.
  • Scissors.


In addition to the mask, he has also designed a filter model that could be made at home for immediate use.

According to Vojtěch, the instructions are simple: cut an empty 2-liter PET bottle as shown below, and seal the inside of the sections with window sealant for convenience. Then, make the closure for the ears by passing through holes in the PET rubber band and stick it to seal.

To finish insert the filter cartridge. You can do this with a few layers of paper towels or napkins.

According to Petráček, the mask is relatively comfortable and, furthermore, he believes that if people had it, it would reduce the possibility that the new coronavirus will not be transmitted as easily.

A simple solution like this can help reduce infections . The filter can be changed and the entire mask is disinfected with alcohol, “he explained.

The Rector is simply trying to help companies when masks cannot be purchased, ” said Lucie Orgoníková, Chancellor of CTU for News.

In addition to the mask instructions, the CTU also contributes to this crisis by producing disinfectants. It supplies them to the Integrated Health System (IZS) hl. from Prague.
