'Not quite a Sand Filter'

The Yamitsu Cartridge Filter ..

Cartridge Filter

Compact and Versatile Filtration Compact and versatile, our Cartridge Filters are designed to give years of trouble-free service. The Cartridge Filter utilises a specially treated polyester fabric, which is pleated into a cartridge. Ideal for ponds/ pools where backwashing may not be practical, cleaning simply involves dismantling and hosing the down the cartridge..

Features include:

  • One piece molded high impact polypropylene construction
  • Automatic air bleed
  • Industrial strength filter fabric
  • Self-centering cartridge mount


Probably not a totally new concept .. but one that applies very nicely with the Koi Keepers alike, all over the world ..  easy to fit easy to use .. and most importantly, easy to clean ..  These cartridge filters are ideal for that final fine particle removal and for polishing the water prior to its return to the pond system ....

Ideal for use in conjunction with a surface skimmers ..or main filters ...

Why not have a spare cartridge at the same time ..  making the simplicity of changing the cartridge even easier and then you can hose down the dirty cartridge at your leisure ..

Available in cartridge sizes ranging from 25sq.ft to 150sq.ft (filter area).

10-year conditional tank warranty.


The Photo on the Right shows one of these Cartridge Filters - fitted to one of our own systems ..

Note the return pipe has first passed through the Heater, but this really does not matter and if you have a heater then there is nothing to stop it going in before the heater ..

Also please note that we have fitted a direct 'purge' to waste which is controlled by the lower ball valve - the upper ball valve is to enable the water from the pond to be shut off and also to isolate the UV if required ..
