I just got this and in the process of running the first gallon of water through it (as recommended by the owner's manual) and am dismayed at how slowly it filters water. It is currently taking about four hours to filter less than a gallon. Does it get faster? I'm running regular tap water through it, not sludge. ??? At this rate it is unusable.
Ceramic drip filters are always slow, but get everything. They tend to be best for base areas, in my experience.
So, would the other filters be faster? I'm using it to filter snowmelt water, which isn't too bad to begin with. I'm currently getting about a gallon every two hours, with the first gallon going much faster than the second.
