The NRP 51mm naked portafilter that includes 2 shot filter basket. Great for observing your process of making a shot of espresso. Issues such as under- or overdosing, inconsistent or incorrect grind size, uneven tamp pressure, or unevenly distributed grinds, can all cause improper extraction.
The portafilter’s handle is made by black plastic. you can unscrew it when you need to deep clear the filter holder (metal parts). Please Note! this Portafilter is 3 ears Designed. if your espresso is 51mm filter BUT use with 2 ears portafilter. that mean this one won’t fits on your model.
One of the most common visible signs that you’re experiencing extraction issues is through channeling (or spurting), which cannot be seen with a standard spouted portafilter. Exposing the bottom of your portafilter basket will allow you to witness these extraction issues first hand, providing an opportunity to diagnose and improve the quality of your shots.
Channeling and spurting can be very messy, but these are very very common. This is not a defect of the portafilter itself, but instead is your coffee telling you that there’s room for improvement in your preparation process (grind size, tamping, distribution, etc.)

Extracting directly from basket to cup leaves more crema intact.
IMPORTANT NOTE: Check with your old portafilter’s size before place purchase. Make sure your Espresso Machine is using the 3 ears handle, and the filter basket is 51mm by diameter !!!
