Just read the title once again. The words speak of a filter. In fact, the model consists of a membrane made of hollow fibers. This part can separate water from other particles present in the same liquid.

When the water passes through the Ultra Filter (UF) water purifier membrane, then suspended particles, viruses, get retained in the membrane.

Do you remember RO water purifier? You have a very good memory. In RO, the membrane can block minute particles whereas this Ultra Filtration water purifier can block a large number of particles.

UF water purifier is only suitable for the water containing low contamination of total dissolved solids. The most important factor is that the Ultra filtration model rarely works when there is hard water.
