How the Five Compare on the Numbers
Eight live pages already rank this pool: by published diameter, by the only published height, by what stops a thin disc folding, by the ring that holds the mesh, by which press the filter is actually for, by the fineness each maker publishes, by the material grade, and by whether the purchase is a flat screen or a complete lid. Every one of those questions is about a single filter.
A coffee bar does not buy a single filter. It buys a supply, and the number on the label is not always a number of filters. Two of these five listings count something else inside their advertised total, and both of them tell you so in the contents bullet, which is where the comparison on this page starts.
What the table cannot tell you is how long any of these last, which is the figure a bar would actually buy on. Four of the five say to replace filters often and none says how often. The closest thing to a durability figure in the whole pool is a reinforced center ring, which two listings name and three do not, and Easyworkz’s 24 month guarantee, which covers the kit rather than the mesh.
What the Number on the Label Counts
Eight Items, Six of Them Screens
YMMIND’s first bullet does the right thing and itemizes: the set includes six pieces of stainless steel mesh for fine filtration, one spiral disc and one cross disc, which it says connect to the runner rod. So eight is accurate and six is the number that matters if you are stocking a bar. The two discs are not padding either; they are the parts that bend and lose their thread before a mesh wears out.
Attsky and Boao make the comparison simple by selling only screens. Attsky states a 6-pack of 4 inch screens with a reinforced center ring. Boao states that you will receive six pieces of french press filters in total, at approximately 4 inches with a 5/16 inch hole. In both cases the label number and the spare count are the same number, which is worth something on its own.
Three Pieces, One Screen
Easyworkz is the one to read closely. It is advertised as a three piece set and its contents bullet lists one stainless steel spiral disk, one ultra fine micro nylon mesh and one stainless steel mesh screen. The listing calls this an innovative four level filtration kit, which is an accurate description of a plunger stack and a poor description of a supply of spares.
That makes it the right purchase for a different job: rebuilding one plunger properly, with a nylon layer no other listing here offers and a stated 24 month guarantee behind it. It is the wrong purchase for a bar that goes through screens, and nothing in the title tells you which of the two you are getting. The contents bullet does, in one line.
Three Diameters on One Listing
Which Figure to Measure Against
YMMIND publishes 3.6 inches in its title, 3.75 inches in its compatibility bullet, and 4 inches in its size field. Those are three different discs. The bullet is the most specific of the three, saying the parts can be used in both 34 ounce and 3.75 inch wide presses, so we have printed the title figure and the bullet figure together and treated the size field as the least reliable of the three.
It matters because the listing’s own closing advice is to check the size carefully before purchasing. That is good advice that the listing makes impossible to follow. A screen that is four tenths of an inch too wide will not seat and one that is four tenths too narrow will let grounds past the edge, and both of those outcomes are inside the range this one listing publishes.
The Pack That Publishes No Diameter at All
Easyworkz asks you to verify the size before ordering and gives nothing to verify. Its five bullets cover the four level stack, the contents, the installation, the compatibility with most 1000 ml and 8 cup presses, and the factory. No diameter appears in any of them, and the only three figures on the listing, 3.31 by 0.16 by 3.31 inches, describe the flat carton the kit ships in.
Attsky, Boao and IBETTERN all do better. Attsky states 4 inches, Boao states approximately 4 inches, and IBETTERN states 4.5 inches for a 50 ounce, 12 cup, 1500 ml press. Those three are the only listings here where a figure in the text can be set against the screen you are replacing before you spend anything.
The Parts of a Filter Nobody Measures
The Hole in the Middle
A french press screen is a disc with a hole, and the hole has to match the rod. Boao publishes 5/16 inches for it. No other listing in this pool publishes it at all, which means for four of these five the outside diameter is the only fit figure you get, and the fit that actually fails is the one in the middle.
That is the strongest reason on this page to measure the screen you are taking out rather than the press. A 4 inch screen from one maker and a 4 inch screen from another may thread onto different rods, and only one of these five listings gives you the number to check it against. The other four say to verify the size and mean the diameter.
The Ring, and What It Is For
Attsky states a unique reinforced center ring that prevents wear and makes the screen last longer. IBETTERN states a reinforced center ring that keeps the mesh flat and stable while pressing and maintains steady brewing pressure. Those two are describing the same failure, which is a thin disc folding under the plunger and letting grounds around its edge.
YMMIND, Boao and Easyworkz name no reinforcement. YMMIND instead claims a higher density screen filtering 99% of used grounds, and Easyworkz claims four levels of micro mesh. Neither of those addresses deformation, and on a bar plunger pressed down hard dozens of times a day, deformation is the thing that ends a screen.
Which One Fits Your Kitchen
You want spares and the wear parts in one order. YMMIND. Six mesh screens plus a spiral disc and a cross disc, 304 stainless, stated to filter 99% of used grounds. Measure your own screen first: this listing publishes 3.6, 3.75 and 4 inches.
A standard eight cup press and a weekly change. Attsky. Six screens at a stated 4 inches, up to 100 mesh, with a reinforced center ring and nothing else in the box to pad the count.
You are not sure the hole will fit. Boao. Six screens at approximately 4 inches, and the only listing in this pool that publishes the hole at 5/16 inches. It states no mesh count and no grade of steel.
A twelve cup press on the bar. IBETTERN, four screens at a stated 4.5 inches for a 50 ounce, 12 cup, 1500 ml maker, with 100 mesh and a reinforced ring. It is also the only listing here written with a coffee shop in mind.
One plunger that needs rebuilding properly. Easyworkz. A spiral disk, a nylon mesh and a stainless screen as a stated four level stack, with a 24 month guarantee. One of the three pieces is a screen, so this is not a supply of spares.
What We Could Not Verify
These are the specifications we went looking for in all five listings and did not find.
- A hole size for four of the five. Only Boao publishes one, at 5/16 inches.
- Any diameter at all from Easyworkz, in a bullet or a field.
- Which of YMMIND’s three figures, 3.6, 3.75 or 4 inches, describes the screens in the box.
- A micron rating or wire gauge behind any mesh count. Three listings give a count and none gives a weave.
- How often any maker expects a screen to be replaced, although four of the five recommend replacing often.
- A weight for YMMIND, Attsky or IBETTERN, in a field or a bullet.
