The water filtering system obtained by grooved
plastic disks proves particularly effective because it utilizes two combined
types of filtering.
The first uses the external surface as filtering panel while the second uses
the disk groves to retain the smaller solid particles.
In this way the bigger particles are retained by the external surface while
the smaller ones are stopped by the gaps between each couple of grooved
disks.
The cartridge cleaning can be easily carried out unscrewing the pressing nut
and washing the disks with running water.
