I think BCPP is a little confused. Line the felt (OR Orlon) filter with 2,3 or more paper filters. Then as each clogs up, carefully dump it's contents into the next paper filter.
Another method that helps is to mix some DE, (filter aid) (food grade, from a maple dealer diatomaceous earth, other sources will not likely be the correct size even if food grade). Mix in about 1/2 cup per 1 gal of hot syrup, then filter it. The DE will be caught by the filter and form a filter cake. Using this method you will only need 1 prefilter. When done filtering, wash in plain hot water, do not wring, just squeeze. Hang to dry.
I used to use 3-4 pre-filters, and an orlon filter under it. I got as much as I could filtered, then I cleaned the prefilters separately from the orlon. That got washed in clean hot water and dumped back into the pan to boil, recovering most of the sweet in it.

Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
