Talk:Coffee filter

I've removed the redirect to drip brew; is the usage of coffee filter for drip brew common enough to warrant a dab page? Ambarish | Talk 23:10, 19 May 2004 (UTC)

Filter coffee is very common all over the world, arguably until the rise of Starbucks bringing espresso chains it was the most commong form that people would have, especially at home or work. It is not just an Indian term or method of preparation. Paper filters, metal (gold or otherwise) filters, all are very very common everywhere. We need to ensure that this is reflected in the articles on coffee filter, filter coffee and coffee (drink). --VampWillow 08:25, 2004 May 20 (UTC)

All right, maybe we should wait until the discussion on Coffee dies down. Just a doubt, though. Don't Starbucks etc. use coffee percolators or coffee-makers though? Are paper-based coffee filters (essentially a piece of filter paper?) used still? Ambarish | Talk 08:35, 20 May 2004 (UTC)

agree with useing Coffee (drink) to discuss. Starbucks etc use espresso machines (big and look espensive so easier to charge silly prices!) and paper and metal filters in very common use in UK (probably equal with cafetiére, maybe higher) --VampWillow 09:23, 2004 May 20 (UTC)

Is the following in error? I wonder if the original author meant to say "Metal or "nylon" mesh filters do not remove these components." I have never heard of paper mesh filters. From the page: "Paper filters remove oily components called diterpenes; these organic compounds, present in unfiltered coffee, appear to increase the risk of coronary heart disease. Metal or paper mesh filters do not remove these components.[1]" KitINstLOUIS (talk) 17:19, 11 October 2013 (UTC)

this does not make sense: “This enables it to trap the dirt particles that are big and the small water particles can flow through, thus this gives us pure water.” Swoolverton (talk) 00:38, 2 January 2014 (UTC)

This article is one of many of the subject of coffee that needs to be expanded

Looking around the different articles on Coffee brewing and coffee related apparatuses I have found that many seem to be missing at least some notable aspects of that specific subtopic on Coffee. This one on coffee filters is missing the following info which should be added IMO to make the article more complete:

• There is not enough info in the article on permanent/non-paper coffee filters. Permanent filters can be made of metal (commonly stainless steel or aluminum) and in some case may be gold-plated. The other type of common permanent filter is cloth coffee filters. We should also include what are commonly viewed as the pro and cons of permanent filters vs paper filters such environmental concerns or taste concerns (permanent metal filters don't filter coffee quit as well as paper and thus effect mouthfeel of coffee which some don't like).
• We need to better explain the the three most common different Coffee filter shapes, the cone/conical filter, basket filter, and disk filter (Used by some specialty coffee maker devices like the AeroPress and comes in non-standard sizes specific to the coffee making device it's designed to be used with).
• Coffee filters come in different sizes. In North America, the their are two common filter sizes system used, one for basket and one for conical (cone) filters. Conical filters come in sizes #1, #2, #4, and #, with #2 and #4 being the most common. These numbers indicate the filter number of cups and coffee maker type (electric vs non-electric) it's designed for. For example, a #2 cone filter is designed for two to six-cup electric coffee makers and one to two-cup non-electric coffee makers.For basket filters, North American sizes are measured in Junior or regular sizes. While the article does briefly mention the common standardized coffee filter sizes used for conical paper coffee filters, it should included info what these size numbers mean. We also don't have info on standard basket filter sizes (Junior vs regular).
• Paper filters come in bleach and unbleached varieties and while the article does mention this it does not explain why this is and what advantage and disadvantageous bleached vs unbleached paper filters have.
• Here is an article on "Choosing the right coffee filters" that I used to help me determine what this article is missing on the topic of coffee filters: https://www.roastycoffee.com/coffee-filter/\

Objections?

I feel that a separate article would be a good idea, because there is more than just listed here, and it would be too long for a section. Does anyone object to disabling the redirect and making it its own article? Sage or something (talk) 23:35, 26 April 2024 (UTC)

Yes, I have objections (at present). There has not enough encyclopedic material accumulated for a separate article on the Hario V60 filter yet. --Matthiaspaul (talk) 18:56, 30 April 2024 (UTC)

Readability Issue with Paper Filters:

In the "Overview" section:

Paper filters remove oily components called diterpenes (like cafestol and kahweol). Metal, nylon or porcelain mesh filters do not remove these components. These organic compounds, present in unfiltered coffee, have anti-inflammatory properties. Several studies also indicate that the mild consumption of paper-filtered coffee may reduce the risk of coronary heart disease due to reducing these compounds.

First I found this VERY INTERESTING, which is why I am here complaining about it. It seems "sort of" obvious that the comparison being made is between "drinking coffee made with paper filters" vs. "drinking coffee that has not been filtered through paper", however it's a subtle point and makes you think about it, which IMO is a readability issue. VERY interesting point, and so the Article should hit it hard, and give both sides of the comparison, lest someone assume that "drinking coffee reduces your risk of heart disease". This is a very limited statement, and the limits should be more explicitly expressed.72.180.111.79 (talk) 00:09, 6 August 2025 (UTC)

Are Paper Coffee Filters 100% Paper (Wood Pulp) Fiber?

GREAT Article, IMO and lots of nice detail, and so my question feels sort of nit-picky, however you never know who else might want to know. I do vermicomposting, and want to know if my standard, Walmart, cheap, "basket" style coffee filters are 100% paper, or if there are some synthetic fibers in the filter that might not degrade/decompose. I seem to remember a compost pile years ago that I ran, and the coffee filters seemed to never degrade, so I'm hesitant to put them in with the worms. Maybe they will never decompose, or will off-gas during their degrade and harm the worms, and poison the compost? Be nice to be able to just read this Article and get the answer fast and easy, is the point. Improve the Article, etc...72.180.111.79 (talk) 00:17, 6 August 2025 (UTC)

Most unbleached paper coffee filters are fully compostable, but you should shred the paper into pieces to speed up the process.

I have never seen them personally, but reportedly some odd "paper" filter types feature integrated plastic frames or have coatings, which would obviously make them unsuitable for composting.

I have long switched to Karlsbad-style permanent porcelain filters to further improve the taste and avoid the waste.

Used coffee grounds would probably the best target article to discuss this in better details, if needed. --Matthiaspaul (talk) 08:18, 31 August 2025 (UTC)
