aside from buying or making a vacuum filter system,,,
the t-shirt system can work quite well if one uses tighter weave fabric, then paper filter.
suggestion:
first use a fine stainless filter/colander or french press
then t-shirt
then a tightly knit fabric--think dress shirt or other
finally coffee filter (repeat this step)
patience helps here, but one can carefully squeeze the water thru any of these steps
also, simply letting the tea sit and cool for hours will make things far easier as most solids will sink over time.
