What is the difference between the brown Hario V60 filters and the white Hario V60 filters, apart from the colour?

The brown Hario V60 size 01 filters are unbleached, while the white variant is bleached. An important difference mentioned by customers is that the brown filters drain faster than the white ones. This can affect the brewing time, even if you use the same grind. The taste is generally not affected by a paper taste: both options are known for their neutral flavour transfer.
