This study examines the effect of the unipolar corona discharge on the filtration characteristics of polypropylene nonwoven materials, paper filters, and a two-layer composite material based on them. It shows that the two-layer filter consisting of the Red Tape ashless filter and the spunbond nonwoven polypropylene fabric provides higher filtration efficiency than each of the materials separately. Electret treatment of the samples reduced the amount of polluting particles in the filtrate by ~80% for paper filters and by ~30% for the polypropylene nonwoven material compared to untreated samples. At the same time, the filtration time increased by an average of 1.3 times. Testing the filtration efficiency of two-layer materials in a capsule cartridge with a supernatant liquid for filtering synthetic detergents demonstrated high separation efficiency — the modification of the cartridge increased its efficiency by almost 4 times.
