The new tabbed ones are faster now?

Depending on the coffee it can be anywhere from 30-45s faster. This has had an effect on taste. Nothing else has changed other than the filters. I've tried various coffees with the same results. I can adjust my grind to compensate, but not having consistency between the same filter is annoying.

Has anyone else experienced this? Has Hario made a change perhaps?

The new faster ones have tabs also?

I just switched to the red Abaca filter's and they are exactly the same as the Hario filter's without the tabs. I'm still hitting my typical draw down times.

I can't say that with any authority. All I can say is the latest pack I received draws down faster. If that is a consistency issue or a new design issue, I'm unsure.

Timely post as the carton of Hario tabless bleached I bought is about done. I read Gagne's post on coffee filters from 2019 and just bought Hario unbleached tabbed to try based on his work. Draw down is about 30 sec longer than my old filters which seems contrary to Gagne's tests. Wonder if things have changed again since his post? Subjectively I note the unbleached tabbed filters seem thinner and to stick to the sides of the V60 more than my old stash of unbleached tabless filters. I may get some Cafec's to try as well.

I used a recently Amazon-US purchased 40 box but tabbed today for the first time. They seem thinner and had crape surface on both sides - both of those aspects should promote faster drain. They seemed slow and were 27 seconds slower than the day before (3:51 vs 3:24) but the day before I used a Shimmy sieve on same size grind removing 7.9% in fines. Today was same brew parameters except no Shimmy. With that low of fines, I doubt the fines would account for the 27 seconds longer brew, so these filters seem slower drain.

I didn't read the blog post thoroughly again, but I think it was a theoretical analysis without actually brewing any coffee? In my experience - contrary to the theoretical results - Hario's tabless filters were always faster than the tabbed filters, bleached or not.

There was an updated section in his book with actual coffee. Hario's bleached tabless had a drip rate of ~0.3g/s/cm and the unbleached tabbed ~0.22g/s/cm in his testing. My own experience confirms his findings that unbleached versions of the same paper are faster or less likely to clog at least, which is cool

Yep, just pulled Gagne's book off the shelf and you are right it's more current and the flow rates do indeed differ with/without coffee. Frustrating all the tabbed/non-tabbed and bleached/unbleached options Hario offers. Good news from that graph is that the Cafec traditional and universal filters appear to be close to the Hario untabbed bleached I'm currently using. Will report back when I can test them.

Not exactly an answer to the question, but I've used pretty much every Hario filter out there and I can say that the original, untapped filters in the box make the best cup by far.

Unfortunately, Hario is completely discontinuing them and everything will be tabbed soon.

Got some Cafec Abaca filters. Compared to my old stash of the Hario boxed tabless filters the Cafecs have a similar heft, opacity and are also creped on both sides. Initial results with several coffees yielded similar draw down times too.
