MHW-3BOMBER 58.5mm Espresso Puck Screen, 0.8mm Dual-Layer Stainless Steel Filter, Even Extraction & Cleaner Group Head, Fits 58mm Portafilter Basket, FG5590

For my Breville Bambino Plus ports filter perfectly (54mm). Keeps the group head clean as well which is an added bonus.

It keeps the brew head COMPLETELY clean. I think it helps with channeling as I am only using 7 g in a 7 g basket. Get a holder with a magnet to extract it from the basket after using.

I've tried a lot of puck screens, but these are my go-to. These Bomber puck screens are the perfect thick/thinness to not affect dosing volume while still being rigid enough to not bend, and the stainless steel with perforations also means that I can use the Bomber puck screen magnet to pull the puck screen off before knocking the puck out. No digging around in your knockbox to get the screen out any more! Mesh screens that I've used in the past didn't work with the magnet, which is a huge consideration for me. Definitely improves water distribution, especially for machines like the Breville Barista Express that has a single-sided water dispenser. If you use a bottomless portafilter, you can really see the difference!

Purchased this, and the black titanium coated version, they both arrived 23 days ago. Using these both and alternating between the two to pull 3-6 shots daily total I hadn’t noticed much of a difference. They feel nice not too heavy or light, fit in the portafilter well, clean up easily, and keep my head clean. All in all, works just fine. As of this morning, the screen is beginning to split from the other side as it’s just stuck together. This allows a bit of ground to make its way between the screen and holed part. Without damaging further, it is quite difficult to clean. Unfortunate, as I was a big fan of these to begin with. The titanium coated version has seen a bit more use, and seems to be holding up just fine. When in proper working order, they do a great job of keeping the head clean, and come out of the portafilter very easily. EDIT: Original review 2 stars as the portafilter screen split as seen in the photo. Seller contacted immediately with options to correct the situation. Was prompt, and friendly. Great customer service, will absolutely order from them again.

This is the perfect puck screen thickness. Does not create too much back-pressure. Evenly distributes water comming off from the shower head.

Not a coffee game changer, but here are the benefits: 1) Cleaner operation of group head over multiple shots 2) An extra layer of dispersion to avoid channeling incrementally Negatives: 1) Knocking out requires two steps - knock gently to remove disc, knock hard to remove puck - if you don’t like touching not for you 2) On finicky beans that require a very even distribution and acceptance of water from the group head will actually reduce flow and cause over extraction. So you have to know which beans and grind benefit and don’t from using the disc OR you need to recalibrate grind and pressure for using disc with that finicky bean extraction Overall Better than other screens/discs I have used due to thinness and difference in the two sides. Knowing when and how to use optimizes. Not as big a deal if you dial in on one bean and grind.

This is definitely worth the investment into your coffee shots, it helped my shots come out better and not squirt out the sides, which always made a mess this definitely made the quality of my shots better!

As my title states this is my go to screen. I too fell onto the screen bandwagon and doing my own Coffee beans for many years roasting my favorite single origin, so I know enough about coffee and espresso to be dangerous. With my double boiler machine, one thing that always bothered me , is sometimes it could channel no matter how careful I was with grind tamping and all those other finesse things that we get trapped into. There are lots of opinions on why this occurs, and I have explored them over the years , but I have found a screen, pretty much eliminates any of my channeling problems. So now it came down to just a matter of thickness and mesh size . After quite a bit of testing this disc has become my absolute favorite. A great balance between being overly thick and taking up too much space or being so thin that it becomes flimsy and you get some grind splashing up around the edges. Turns out this is like the baby bear says , just right. I now have no more channeling , clean up is faster. My water screen doesn’t get dirty , nothing but positives. The last picture shows the three screens that I’ve been trying different styles different thicknesses so as you can see, I’ve been through a little bit of testing.

I think this made my coffee better. Just remember to take it out of your compost bin when u knock it out of your portafilter. A few times I forgot and had to dig in my city bins for it.

Good but expensive
