Good insight from what is quickly becoming my favourite YouTube channel

Do you think the paper filter are “safe” if used under pressure?

I mean i frankly don’t think is harmful, overall i don’t use it, but what is used to bind the paper fibers?

Is the white water an effect of the pressure or is really something that is extracted from the paper?

I’ve tried paper a couple times but never been a fan,

There food safe I guess

I’ve been using them for just over 6 months now, at the top of the puck to keep the shower screen clean. Works great!

If you buy scientific papers design for laboratories they re not food safe but the ones you buy from coffee retailers such as good brothers in the USA are rated as food safe.

I thought it was a really well balanced review which presented his opinions but also left the door open to others who have different preferences.

Personally I use a filter on the bottom of baskets. I agree that you lose a little bit of intensity but I do think I pick up more in terms of flavour notes.

Like many others I use a paper filter on top of the puck just to keep the shower screen as clean as possible.

As he rinsed the papers, aren’t the first drops of water just the pressure effectively ringing the paper dry, ie forcing out the water by replacing it with espresso?
Would have been good to see him do an unrinsed one.

I use a Normcore screen on top, the main benefit of which is that I rarely have channeling (proper WDT needles and technique also contributed). And yes, my shower screen is also cleaner.

I also noticed that flow increased, which I adjusted for by grinding finer. I also had to make some adjustments to the Lelit E settings that control the extent of water entering the group head at the beginning of pre-infusion, as the screen takes up puck headroom.

As for paper on the bottom, I did not like the loss of strength and body that came with using paper, especially as this strength is needed in milk drinks. I was using lab (but not food grade) paper but had read the paper chemistry information of both the food grade and lab papers, and was ok with the lab paper. It was Ahlstrom 6010-1250 Qualitative Filter Paper, 2.5 Micron, Medium Flow, Grade 601, 12cm Diameter paper that I cut into 3 paper disks per sheet. It (and a paper disk cutter) are now sitting on a basement shelf.

And… for me… It’s already extra effort/pain to fish the Normcore screen out of the knock box. Adding the extra step of fishing out the paper as well would further increase the effort.
