A Petryanov filter is a type of filtering cloth that is used for fine and super fine cleaning of air and other gases of fine aerosols.
Gases contaminated with aerosols with a solid phase concentration of 0.5 mg/m3 can be cleaned by using these filters.
[1] These filters are commonly fabricated using electrospinning techniques, and were first developed in 1939 by Nathalie D. Rozenblum and Igor V.
