MIMOREEspresso Filter Paper 54mm - 500PCS Unbleached Coffee Paper Filter for Espresso Machine - Disposable Portafilter Paper Espresso Filters Compatible with Breville Barista, Mr. Coffee, & More

better tasting coffee

Like others have pointed out, these are more for replacing the use of a puck screen on top of the grounds, so if you use them on the bottom of the portafilter like I do they don't fit perfectly, but they still function as needed. These combined with a puck screen really mitigate channeling.

Perfect size. Works well in a 2 cup Bialetti Moka Pot. Huge difference with coffee smoothness. Better clean up too!

Much like James Hoffman, I wish paper filters didn't make a difference, cause it's an extra step in puck prep and a tiny bit of waste, however, they do improve flavor.I have to say with these paper filters, although very reasonably priced and no problems with delivery, they seem to be a tiny bit bigger than they should be. It feels the sweet spot should be at 57.Xmm for 58mm portafilters.In the picture you can see a DEX precision 58mm basket, it is wider at the bottom than cheaper/worse baskets (like the stock one of most machines), yet it barely fits, and you have to wet it before puck prep, still, it feels it could be improved if it was just a tiny bit smaller.The process as a whole... not sure I would recommend paper filters, but these ones are okay and cheap. Maybe they would work even better on those newer wafo/weber/sworks baskets which have the widest bottom afaik.

I love these filters it fast and easy to use if I'm in a hurry

These little filters make emptying the grounds easier. Glad I got them.

They seem to be real clean and clear. No flavor from them that I can notice. Although...I just use them at the top of the puck. They work like a charm to keep the shower screen clean.
