This is probably a bit overkill as the amount of retained water is small, but it’s an easy thing to do.

I have not yet accumulated any practical evidence for this, but I suspect that using unbleached filters might both reduce channeling in all situations (because flow is more uniform across the filter surface) and make your brew more robust against clogging (because of the smaller number of large pores), all while having a slightly faster flow rate (because there are more pores per unit surface) ! If you are really afraid of paper taste or hate using a lot of water to pre-rinse your filter, they might be the optimal solution for you, but keep in mind that they flow much slower than other paper filters. water will take preferential paths across your coffee bed and won’t extract in a very uniform way.

That isn’t too surprising, as we might expect clogging to happen a little deeper than the filter surface. Hey Jonathan, has your opinion on tab vs tabless changed in the past few months? Lightning quick flow rates through the filter let you adjust grind size and other variables to achieve... Hario's V60 drip scale has become one of our favorite brewing tools.
