A fiber-paper based Diesel particulate Filtration (DPF) apparatus possessing high filtration efficiency and a high porosity, the apparatus comprising at least two rollers capable of rotating over rotors with the help of a controlled motor and capable of supplying fiber paper at the exhaust gas inlet. As the exhaust gas moves over the fiber paper supplied from one of the rollers, the soot gets gradually collected on the fiber paper and keeps on increasing the backpressure thereon. The moment when the backpressure increases beyond a limit, the loaded section of the fiber paper is replaced by fresh fiber paper from the other roller. The loaded fiber is sent to an off-board regeneration facility for regeneration.
