## Overview

The IMS Big Bang Precision Filter Basket is a high-performance 58mm stainless steel basket engineered with 585 holes concentrated at the center to ensure uniform espresso extraction. Made in Italy, it fits most E61 group head portafilters and holds 18-20g of coffee, enhancing sweetness and reducing acidity for a superior double espresso experience.

## Description

The latest innovation from IMS. Holes are distributed towards the center to direct the flow of espresso. There are more holes in the center and they have less disctance between them. This pattern is specifically designed for bottomless portafilters. The basket has flat bottom. Available in 4 heights with different capacities according to the type of coffee used. For 58-58.5mm tampers. Ridgeless. Border 70mm. The main characteristics we found out the BIG BANG filters emphasis was the SWEETNESS. The extraction is very uniform , it exalts the sweetness and reduces the acidity. We don’t suggest to use the BIG BANG filters with citric (light) coffees since they sweetened espresso and modify characteristics.

Review: Nice upgrade for my 20 year-old Isomac Millennium - While cleaning my Isomac Millennium (E61) I decided, after 20 years of use, to try one of the puck screens folks are using these days. The puck screen on the Millennium is not at all easily removable so cleaning it well is a real pain involving tons of backflushing. When the puck screen came, I realized it wouldn't fit in the tapered OEM basket, so that led me down the path of getting a new basket with straight walls that would fit my portafilter. I'm happy to say that this basket fits perfectly in my portafilter and also accepts my 58.5mm puck screen (which does indeed help a lot with the grouphead screen staying clean). My espresso is also notably sweeter, though I'll have to spend more time with this basket before I can say it wasn't due to my latest cleaning. I did have to grind a bit finer with this basket, so I would expect some impacts to flavor. My tamper is 58mm, so it does leave a few fines around the edge, so I'll probably upgrade my tamper to 58.5mm next. Overall, the basket seems well made, looks cool if that's important, and my espresso tastes great.
Review: Best Filter Basket - Compared to the two OEM filter baskets, one coming with the Espresso machine and one coming with the bottomless portafilter, this IMS Big Bang is definitely the best that I can tell visually from the espresso extraction through a bottomless portafilter. Less but finer grounds help as well.

### ⭐⭐⭐⭐⭐ Nice upgrade for my 20 year-old Isomac Millennium

### ⭐⭐⭐⭐⭐ Best Filter Basket
*by F***U on January 12, 2026*

Compared to the two OEM filter baskets, one coming with the Espresso machine and one coming with the bottomless portafilter, this IMS Big Bang is definitely the best that I can tell visually from the espresso extraction through a bottomless portafilter. Less but finer grounds help as well.

### ⭐⭐⭐⭐ Great basket for better espresso
*by J***N on December 4, 2025*

Such a great basket! Easy to clean as usually my puck leaves no residual grounds in the basket. I feel as if my shots are more consistent based on the reduction in channeling that I am witnessing. My only complaint is that my magnetic dosing collar doesn’t really stick to this basket which can be a pain. I sorta just hold my collar on with my thumb while dosing to keep it on there
