Coffee Filter Sizes Explained – Discover Out What Filter You lot Demand

If you're confused about all the different sizes of coffee filters I'm not surprised. I ended up down a rabbit pigsty trying to find what all the different sizes are.

To the point where I bought a pack of every size just and then I could compare!

So if you lot're dislocated as to what filter you might need for your coffee gadget look no further I've got a complete rundown of the sizes below starting with the smallest and going to the biggest, I've included the meridian and a crude diameter of the open filter.

I've likewise linked through to Amazon where they're available and so you can social club them straight from here, just click the name in the list beneath. I went for Amazon because if you lot get the size wrong you can easily render them.

Selection of Melitta coffee filters

These are all based on the Melitta coffee filters, they are the original java filter and to a lot of people the gold standard. Whatsoever other filter using this sizing has based it off Melitta so they will exist the same size or only slightly different.

I bought another make of #iv filter simply to check this was the case and it is, there are only a couple of millimeters of deviation between the two. Nowhere near enough to affect the taste or how yous brew your coffee.

#2 vs #iv Java Filter The Differences Explained

These are the two about common filter sizes, and the ii that cause the most confusion.

Y'all've probably sat looking at all the filters yourself, looking at 2 most-identical filters except i says it'south a #two filter and the other says it's a #four. So what'southward the difference?

The difference between a #2 filter and a #4 filter is the size. A #two filter is fabricated to fit a ii-6 cup coffee car or a ane-2 cup cascade-over and a #4 filter is made to fit an 8-12 loving cup java maker

That's all, as long as they're the aforementioned make and they say they're the same blazon (likely a cone java filter) then you just demand to get the right size for you

Can You Utilise A #4 Filter In a #2 Device or Vice Versa?

The big question isn't if you can become away with buying them, it's that you've already bought the wrong size and are wondering if you lot tin can get abroad with it, aren't y'all?

If you want to apply a #4 filter in a #ii size java maker you're going to demand to trim information technology with scissors. Like shooting fish in a barrel plenty to do, just put it in your coffee machine and see how much sticks out the top and then cut information technology downward to the right size and then the tops are level and y'all tin can shut the lid.

You tin potentially put a smaller filter into a bigger device, you'll just have to exist extra careful when you're adding your java grounds. Depending on the divide you might not go the same coverage of water over your grounds but simply endeavour it, it'south worth a shot if you've already bought them and can't return them.

Are #2 and #4 Filters Different Thicknesses?

Nope, they are made the same way, the only difference is the superlative and the diameter, the actual paper quality is the aforementioned and they make the same java. If y'all gustatory modality a deviation it's more likely due to the corporeality of grounds and how the water is poured on them rather than the quality of the filter itself.

1×2 vs #two vs 102 Coffee Filters?

1×2 is Meilittas proper noun for the #2 filter it ways 1 filter for 2 cups of coffee.

In that location are a confusingly large corporeality of sizes of filters which seems to all exist slightly different, and the 102 is one of them. 102 was the size before coffee machine sizes were somewhat standardized.

The 102 filter is slightly bigger than the #ii, it'south not as steep-sided making information technology wider at the top and information technology'due south not quite as alpine.

The 102 filter was originally made before there was a proficient fashion to make java, they were more than or less a random sized coffee filter you could pour your coffee through. A smaller amount of coffee than a 103 or 104 filter.

Only now Melitta even so has some java makers that are a 102 size and that's what matches up with the 102 filters. The primary one existence there 102 porcelain filter, I'm honestly not sure why they still brand this if information technology's such an outdated size to their other products just people must be buying it.

If you asked me a lot of confusion and headaches would be fixed if everyone could agree what size filters would be the most useful but alas without this the world does keep turning.

All three are close enough in size that you could likely go abroad with using them interchangeably. Always purchase the proper recommended size of course but if you wanted to you could.

What size is a standard coffee filter?

If you've got a coffee motorcar and you don't know what filter to get I tin can assist.

A standard java filter is a 2 pint, viii-12 cup, handbasket filter for a drip coffee motorcar (see more than on what drip coffee is here). And if that doesn't expect right to what you've got then you lot'll likely want a #4 filter.

If you've but bought a coffee machine without too much idea I'd say in that location's a 95% take a chance that you lot've got one of these sizes. Always a chance you didn't but when I go into people's houses and accept a nose at their java set upwards (because I have to) an 8-12 loving cup drip machine is commonly the get-go matter I see.

What is the pore size of a coffee filter?

I tin can't seem to get a straight answer for this, I found a patent for a coffee filter with a maximum cascade size of 20 microns but elsewhere you seem to get a range from anywhere between 15-100 microns.

And so very small is the respond just I'm sure that's not what you came for!

For comparison, a fine mesh strainer has a pour size of around 800 microns, then coffee filters are one of the finest filters y'all get, smaller than a cheesecloth too.

Concluding Thoughts

While it can seem disruptive (I know I was confused) I hope this helped, and if y'all're still dislocated or yous were looking for something else please let me know in the comments and I tin help yous there.
