Perfect Size for my Krups Forced Steam Coffee Maker
Exactly what I needed for my Krups since it was discontinued. Found some on ebay without box for much more. These are fairly priced and work perfect.

Great alternative to Whatman
Slow flow filter paper performs just as well as Whatman filter paper but is much cheaper.

Very strong filter, Qualitative Filter Paper 15cm Lab Filter Paper, Grade 2
The filter works very well and requires a significant amount of time for materials to percolate through. The connect version are probably much better for filtering out material but their cost difference is substantial. Used to filter out motor oil to inspect for engine damage.
