Camlab 1171052 Grade 601 [1] General Purpose Filter Paper, Medium Filtering Speed, 55 mm Diameter (Pack of 100)

These were bought to match the same diameter of the stone funnel I bought. The funnel is nice and flat and this fits in nicely. The only thing I would have liked is if the filter was finer. I guess it all depends on what you want the filter for but I would say this is probably the equivalent of a coffee filter. Other than that it was durable and fit well so no real problems.

Good quality lab filter paper. I use this for the portafilter in my coffee machine. Works well.

Grwat filter

These were good quality filter papers, but not suitable for my requirements.

Useful
