How the Five Compare on the Numbers
Four of the five picks publish a width, a depth and a height. Two of those four also publish a weight, at 0.33 pounds for the KNODOS 58mm set and 0.15 pounds for the DITOSH moka pot funnel. The Normcore 58mm V2 and the MATOW 54mm V2 leave weight blank, and this page records that as not published rather than inferring it from the aluminum body either maker describes.
Height is where the five separate most cleanly. The Normcore 58mm V2 publishes 0.59 inches, the MATOW 54mm V2 publishes 2.13 inches, and the gap between them is 1.54 inches. The Zany Zest ring sits at 1.22 inches and the KNODOS 58mm set at 2.0 inches. None of those figures is described by its maker as a clearance measurement, so treat them as published dimensions only.
The table says nothing about how grounds behave on the way through, how firmly a magnet holds a particular basket, or how a wooden ring ages. It also cannot tell you whether a 0.59 inch height clears your grinder chute, because no maker publishes a clearance figure. What it does show is which makers gave a complete set of numbers and which left a field empty.
Where the Published Text and the Dimension Fields Meet
The Zany Zest listing converts cleanly
The Zany Zest feature text gives a 31mm height and a 70mm flared outer diameter. The dimension fields give 1.22 inches of height, and 31mm converts to about 1.22 inches, so the two agree. That kind of internal consistency is worth checking on any listing, because a maker who publishes a figure twice and matches it is easier to plan around than one who publishes once.
The same listing states a 58mm base inner diameter and a 21.6g weight in its text while the weight field is empty. That is a partial gap rather than a contradiction: the maker does publish a weight, just not in the field a comparison table would read. This page reports the field as not published and notes the text figure separately.
The DITOSH listing works in centimeters
The DITOSH funnel publishes 3.07 inches of width and depth, which matches the 7.8 cm lower outer diameter given in its text. Its upper ring is stated at 8.8 cm, wider than the body fields describe, so the flared top is a text figure only. The maker also asks buyers with non octagonal pots to measure a mouth between 7 cm and 7.1 cm.
Weight is published at 0.15 pounds, the lighter of the two published weights on this page. Against the KNODOS 58mm set at 0.33 pounds, the difference is 0.18 pounds. That is the only weight comparison the fact sheet supports, and it is stated here without any claim about how either feels in use.
What the Missing Figures Cost a Buyer
Two picks publish no weight
The Normcore 58mm V2 and the MATOW 54mm V2 both leave the weight field empty. Both makers describe an aluminum or stainless steel body, but neither publishes a figure, and this page does not estimate one from the material. A reader who needs a weight to compare against another funnel will not find it on either listing.
What both do publish is a full three figure dimension set. The Normcore 58mm V2 gives 2.95 by 2.95 by 0.59 inches and the MATOW 54mm V2 gives 2.87 by 2.87 by 2.13 inches. The height difference between them is 1.54 inches, the largest gap between any two picks on this page that share a basket size class.
Opening diameter is the rarest figure
Only two of the five state an opening diameter in their own text. The Zany Zest ring gives 70mm at the flare and the DITOSH funnel gives 7.2 cm at the lower inner ring. The Normcore 58mm V2, the KNODOS 58mm set and the MATOW 54mm V2 publish no opening figure at all, so the working mouth of those three is unknown from the listing.
Magnet counts are more common: nine for the Normcore 58mm V2, eight for the Zany Zest ring, twelve for the KNODOS 58mm set and eight for the MATOW 54mm V2. The DITOSH funnel states no magnet count, which fits a moka pot funnel that sits on a pot rim rather than snapping to a steel basket.
Which One Fits Your Kitchen
Buyer who plans around a height figure. The Normcore 58mm V2 publishes 0.59 inches, the lowest height figure among the five picks. If a published height is the number you build your setup around, that is the figure to start from.
Buyer who wants a wood body and a stated opening. The Zany Zest ring is the only solid walnut pick and the only one that states a 70mm flared opening. It publishes 2.76 by 2.76 by 1.22 inches and a 58mm base inner diameter.
Buyer who wants a puck screen in the box. The KNODOS 58mm set pairs its funnel with a 58mm puck screen and publishes 3.0 by 3.0 by 2.0 inches at 0.33 pounds, the heavier of the two published weights here.
Buyer on a 54mm Breville basket. The MATOW 54mm V2 publishes 2.87 by 2.87 by 2.13 inches and names Barista Express, Pro, Touch, Bambino Plus and Infuser among compatible machines. Weight is not published.
Buyer brewing in a moka pot. The DITOSH funnel is the only moka pot pick, published at 3.07 by 3.07 by 1.49 inches and 0.15 pounds, with a 7.2 cm lower inner diameter stated for 6 cup octagonal pots.
What We Could Not Verify
Several figures a buyer might want are simply absent from the listings, and no amount of reading fills them in.
- The weight of the Normcore 58mm V2 in pounds or grams.
- The weight of the MATOW 54mm V2 in pounds or grams.
- The opening diameter of the Normcore 58mm V2, the KNODOS 58mm set and the MATOW 54mm V2.
- The magnet count of the DITOSH moka pot funnel.
- The puck screen thickness for the KNODOS 58mm set.
- Any published clearance figure that would connect a funnel height to a grinder chute.
