I cut up a Hario syphon filter, in the shape of an aeropress filter, which the result looks almost identical to the above product. Funny that.
My thoughts, the cup tasted nice. Better than the S-Filter? Dunno about that.
It was a nice cup, little fines, bold and thick body. Very much like the S-Filter but I think the S-Filter allows through even more flavour and oils.
I'd need to do some side-by side comparo's, but honestly, the effort in storing (in water), and cleaning the cloth filter is just absolutely painful. I threw away my franken-filter after only a few uses because it was brown and too difficult to clean. Fun to do some brewing with the different filters though!
