A puck screen sits above the tamped coffee; a bottom paper filter sits beneath the grounds. Compare placement, basket fit and headspace before choosing either or using both.
The Problems They Address
Water enters the basket from the group head above. A puck screen adds a reusable contact layer above the coffee, while a paper filter beneath the grounds changes the layer at the basket’s outlet.
Neither accessory is essential for every setup. This comparison covers a screen on top and paper on the bottom; paper placed above the coffee is a different arrangement.
What Is a Puck Screen (Dispersion Screen)?
A puck screen is a disc placed above tamped coffee. Thickness and mesh opening are separate specifications: thickness describes how much space the screen occupies, while mesh opening describes gaps in a mesh. Ask for both measurements when comparing products.
Primary functions:
- Water contact: A screen adds a layer between the shower screen and coffee. Its effect depends on the screen and setup; even wetting is not guaranteed.
- Shower screen cleanliness: A screen can help keep grounds from contacting the shower screen, but still needs cleaning itself.
- Clearance: The screen occupies space above the puck. Confirm the machine’s required clearance before use.
For the available options, see the Dual Dispersion puck screen $4.99. Confirm the selected item’s measured diameter, thickness and package quantity before ordering.
What Is Espresso Filter Paper (Puck Paper)?
Filter paper for espresso $4.99 is a circular paper disc offered here in 51mm, 53/54mm, or 58mm sizes. It is placed inside the basket, beneath the grounds, between the metal basket and the coffee puck.
Primary functions:
- Cleanup: Paper may help with removing a spent puck, but inspect and clean the basket between shots as needed.
- Particle filtration: Paper adds a filtering layer at the bottom of the coffee bed. Do not assume it prevents every basket blockage.
Bottom paper primarily acts at the output side of the coffee bed. It is not a replacement for a screen placed above the grounds.
Do They Change Extraction Flavor?
Taste and flow can change when you add an accessory. Compare it in your own setup while keeping the rest of your recipe consistent:
- Puck screen: Compare shot flow, taste and cleanup; do not assume a screen will solve channeling.
- Filter paper: Retaining particles does not establish a predictable change in total dissolved solids (TDS). This guide does not report a measured TDS change for the paper sold here.
Judge whether either accessory makes your routine easier or your results more repeatable. Neither guarantees a flavor improvement.
Which Do You Need?
| Your goal | What to consider | Check first |
|---|---|---|
| Try bottom filtration or easier puck removal | Paper beneath the grounds | Fit at the basket floor; inspect for folded edges |
| Add a contact layer above the coffee | Puck screen above the tamped puck | Diameter, thickness and headspace |
| Keep grounds away from the shower screen | A correctly fitted puck screen may help | Continue the machine’s normal cleaning schedule |
| Try both arrangements together | Paper below and screen above | Fit and clearance with your usual dose |
Before combining a screen with paper, check the intended placement of each item and the space above your usual dose. You may need to adjust dose or accessory choice to maintain the required clearance. Follow the basket and machine instructions rather than forcing the portafilter to lock.
Sizing and Compatibility
Choose the size for where the accessory will sit. A tapered basket can be narrower at the floor than near the tamped surface, so top-screen and bottom-paper diameters need not be identical.
For the listed 51mm, 53/54mm and 58mm options, measure the basket at the intended placement and confirm the item’s actual diameter.
Basket dimensions can vary within a machine family. The 51mm, 53/54mm and 58mm labels are starting points for comparison; confirm the selected item’s actual dimensions and fit, especially for a combined 53/54mm option.
FAQ
Can I use a puck screen and filter paper together?
Yes, if both are suitable for the intended placement and your basket has the required clearance. Check headspace again after adding the screen with your normal dose.
Does a puck screen replace backflushing?
No. Follow your machine’s cleaning instructions, including backflushing where specified. A screen or paper filter does not remove that maintenance requirement.
Is mesh size the same as screen thickness?
No. For example, Normcore lists thickness and mesh size separately. Its measurements describe its own screen, not the 1988Coffee product.
Which side of an espresso puck screen faces up?
Follow your screen maker’s orientation instructions. If the two faces differ and no top side is identified, ask the maker before use. Do not assume every screen can be used either way up.
