The durable final propylene cartridges are made impermeable in the carbon block, and there are previous filters which provide a solid structure.
Nylon net surrounds the fiber pre-filters, in order to provide additional support.
As the water passes through the pre-filter, the solid carbon block physically traps the particles and chemically absorbs the various chemicals, pesticides, herbicides and certain heavy metals which remain in the water. Since the catalytic, solid, compressed carbon block filter which measures 0.5 micrometers is densely compacted, its surface is maximized and the water remains in contact with the filtering material for a prolonged period of time, which ensures a constantly high performance level.
Its pre-filter traps the dirt, the sand and the particles which affect the taste, odor and clarity of the water
(Laminated Pre-Filter with nanotechnology).
The particles which are too small to be mechanically trapped are subsequently absorbed electronically by the surface of the pre-filter.
