Rhino filters ?

ok guys the time has come to change my filter, i think....

the outside material has gone from white to black, as i have never done this before just hoping you could put me in the right direction...

do i just order a new fabric that wrapes around the filter? or do i need to change the charcoal inside somehow, i have no idea...


thxs in advance

how long have you had the filter? They usually last anywhere from 6 months to a year depending on use and the humidity in your room. You may just need a new pre-filter. The pre-filter just collects particles from entering your filter. You can substitute aquarium filter fiber from pet shop supplies if you can't find a replacement filter or if it's too expensive. Hope this helps
