PM 2.5 umnatha wokunqanda uthuli usetyenziswa kwifestile kunye nenkqubo yomnyango ukuthintela i-HAZE ne-FOG ekungeneni endlwini.Zisetyenziswa ngokubanzi kwihlabathi liphela, ngakumbi kwiimarike kuMbindi Mpuma.
Izikrini zefestile ezichasene nenkungu azibonakali zihluke kwiiskrini eziqhelekileyo zefestile.Kodwa ngokungafaniyo nezikrini eziqhelekileyo, lo maleko obhityileyo wefilimu uzaliswe yimingxuma engabonakaliyo ngeso lenyama. Iipore ze-molecular-scale zivumela kuphela iimolekyuli ukuba zidlule, ngoko ke amasuntswana amahle afana ne-PM2.5 anokuvalwa yifilimu ebhityileyo ngaphandle kokuchaphazela ukuhamba kwamacandelo e-molecular njenge-carbon dioxide.
