Precision Funnel 41:
The Precision Funnel 41 fit exactly 13mm above the sieve and therefore fit under most common grinders, e.g. from ECM or Mazzer. Attention, if the portafilter is held above the sieve by a small "metal nose" so that the portafilter does not have to be held during the grinding process, the Funnel will not fit.
The Precision Funnel 41 "for Eureka mignon" were specially developed for this model and do not fit the "Atom" model range.
Precision Funnel 58:
The Precision Funnel 58 fit exactly 25mm above the sieve and therefore fit under most common grinders, e.g. from ECM or Mazzer. Attention, if the portafilter is held above the sieve by a small "metal nose" so that the portafilter does not have to be held during the grinding process, the Funnel will not fit.

How do I know if I have a 58mm strainer?
The 58mm is the inner diameter of the strainer. Just take your portafilter out of the brew group and measure it as shown in the picture. Important: If the inner diameter is just under 59mm, then it is called a 58mm strainer. The sizes "58.0mm and 58.5mm" fit for this filter baskets.
