Precision filter baskets from IMS
The essential difference between conventional filter baskets and the precision filter baskets from IMS Filtri lies in their construction and the materials used.
First of all, the precision baskets from IMS Filtri are made from high-grade stainless steel that resists corrosion and lasts. That helps keep the coffee's aromas from being altered by other materials.
Second, the even and precise perforation of the filter baskets is a key factor. The precision baskets from IMS Filtri feature a carefully calibrated, constant hole size, which allows for an even extraction of the coffee. Conventional filter baskets, by comparison, often have irregular and inconsistent hole sizes, which can lead to an uneven extraction.
IMS Filtri also uses nanotechnology coatings on its filter baskets. These coatings are designed to reduce coffee residue build-up and support an even water distribution during extraction.
At the end of the day, the precision baskets from IMS Filtri are aiming for one thing: a more even extraction. What you make of that is something you decide during the Dial-in – and whether you like the result is for your palate to decide.

Frequently Asked Questions About Precision Filter Baskets
What sets a precision basket apart from a standard basket?
The perforation. In precision baskets, the hole size is calibrated and consistent across the surface, often with a defined hole pattern. Standard baskets vary more – so the water spreads out less evenly.
Can you really taste the difference in the cup?
Usually yes, but only once the grind size and distribution are right. A precision basket doesn't fix poor preparation – it removes one source of error once everything else is in place.
Do you need to adjust the grind size after switching?
Usually, yes. A different basket changes the flow. Expect to need to re-dial after switching – that's normal and not a sign that something is wrong.
What size do you need?
It has to match your portafilter – 58 millimeters is the common size. Also pay attention to the height and the dose the basket is designed for – an 18-gram basket doesn't work optimally with 14 grams.
How do you care for a precision basket?
Like any filter basket: backflush it regularly and treat it with a cleaning agent from time to time. Coffee oil settles in the fine holes and measurably changes the flow.
Does a precision basket fit any portafilter?
Not automatically. The diameter, height, and the shape of the rim all have to match, otherwise it won't sit correctly. When in doubt, just ask – we know the common combinations.
