Mechanical filter media trap suspended matter and dirt particles. This takes place at various stages:

 

Firstly, before the water flows through the rest of the cleaning process, EHEIM MECH and EHEIM MECHpro provide high efficiency.

 

EHEIM FIX is the ideal material to use as a separation layer between the mechanical and biological filter media .

 

And for fine filtration at the end, before the water returns into the aquarium, EHEIM SYNTH is the ideal material to use.

 

EHEIM MECHpro

Prefilter material also for trapping small dirt particles and biological conditioning 

 

The spiral shape  ensures the trapping of even small dirt particles. The high quality, completely water-neutral plastic allows easy and residue free cleaning. Yet the surface structure allows the colonisation of cleaning bacteria and therefore also provides a biological cleaning process. MECHpro is ideally suited for use in combination with SUBSTRATpro or bioMECH.
