Review: Great for espresso lovers! - These fit nicely into the bottom of our 54mm espresso machine portafilter Some influencer said paper filters cut out a component of coffee that can increase LDL & cholesterol but all I know is that with one of these in the bottom, my espresso tastes a bit smoother and no less intense. Also, bc the grounds no longer get into the tiny holes in the bottom of the portafilter, the brew comes out –> faster <– than before so I now use a finer grind. Nice & faster!
Review: great quality - filter papers were great good quality and were just what i needed for filtering fine gold particles
