Beadfilter

Bead filters are self-contained filters. This has the advantage that they can be operated above and below the water level. The bead filters are filled with millions of tiny plastic beads. Finally, the filter provides mechanical and biological filtration. This means that the smallest dirt particles can be retained (up to 10 microns). Mechanical pre-filtration must take place outdoors. In an internal holder, the bead filter can do without additional mechanical pre-filters.
