The screen reduces clumping and static, but is not "necessary".

You may also want to replace the portafilter support fork - if you are using portafilters with spouts on them you will for sure. Bottomless portafilter users won't have to worry about it, but portafilters with spouts on them will stop short of being centered directly beneath the chute using the existing fork. For Super Jolly users, select the MAZ_8MJ. For Mini users, select MAZ_8M.

Your existing Mazzer doser lid will fit perfectly. This version fits both the Mini Mazzer and Mazzer Super Jolly. For all other models, use MAZ_180
