Can you share a link to the store you buy the paper filters from?

One thing though is a thinner ones are easier to bend too...

Are the 58mm papers?
If so, where to purchase them by the thousands?

I use Aeropress filters, which are 64mm. They come n packets of 350. Because I have a 51mm basket, this trick may not work with your 58mm basket. I "tamp" a stack of 4 or 5 filters into an empty basket. The paper curls up around the tamper base, and stays preformed afterwards.

Hey there:

A couple of years ago, I was asked by a customer to improve the extraction yield of a particular machine in their product line. The work included a redesign of part of their group, then a study of the effect that some commonly available components had on extraction yield. For the group I was working on, IMS competition filter screens improved extraction yield. I don't think that thickness is as important as even distribution of water and the ability to keep the holes clear.

Hi Greg,

Totally agree, that's why I changed over to an IMS competition shower screen four years ago on my BDB. I'm still trying to totally understand the top puck screen's utility besides group head cleanliness. I can visualize the flow dynamics across the puck, so it makes sense from that aspect.

Since the OP regards puck screens, I just want to point out that these paper filters (I too bought 1000 of them from Amazon--and they are fantastic) go on the bottom of the filter screen, unlike puck filters which of course go on top of the coffee...

Using both makes a lot of sense and should get you close to what you get from those costly WAFO baskets discussed on another HB thread...

@Pressino - are these paper filters not suitable to be used as deposable puck screen replacement (on top of the coffee)? I can see the benefit there, but have no interest in adding a filter below the coffee. I can avoid channeling just fine with proper puck prep and like the amount of fines/body and mouthfeel I'm getting without an extra paper filter. I don't wish to change this.

My religion allows me to use the paper filters on top of the puck too.
