Water filter for drinking safe consumption?

I'm using a water filter for drinking which consist of a four stage catridge: activated carbon, silica sand, zeolite and mineral sand. Lately, I notice very small particles sentiment at the bottom of the mineral pot where the filtered water is stored. I believe this is from the filter catridge as there are large pores where the particles may pass through. Does this render the water unsafe for consumption?|||if the filter has broken, then it is not recommended that you drink from it as it contradicts its own purpose which is filtration. Anyway, I don't think that you would get sick from drinking it but better play it on the safe side and NOT drink it anymore. Usually, filters have their lifespan and should be changed every so often, depending on the usage or length of time used. hope this helps
