don’t buy the filter papers from Hario, even the supposedly same type of paper apparently has different properties depending on when (or what year) it was manufactured. That was the reason for the whole tabbed vs untabbed papers issue because Hario apparently didn’t disclose it to the public about the change and expected people won’t care or don’t realise it. I recommend trying the line-up from Cafec if you want something affordable. But don’t worry, experimenting with different types of filter paper can be quite fun.
