I tried one for a bit, it was difficult to keep clean. James Hoffman has a video on these, I recommend checking it out.

I use something similar that I bought in Taiwan as a backup to paper filters, since I am often traveling and can’t always find v60-style filters. Some thoughts:

• It can be annoying to clean
• When I want more than a rinse, I wash it extra by boiling it in tea; that seems to work well.
• It does have a bit of a different flavor compared to paper. As a light-roast drinker who grinds with a Timemore C3, I prefer paper for taste. In the James Hoffman vid other people linked, he describes it as “extra richness and body” for light roasts, but I kinda describe it more as “clouding some of the bite and clarity”. It’s definitely still quite good, and I still prefer the cloth over French press.
• I do find it quite convenient for my use as a backup to paper filters in my “ultra-portable” setup.

Pictured here with small *PAT Tetradrip. A proper v60 is 100% better taste than the Tetradrip; but it’s a really convenient foldy-size.

That is the worst, most appalling name for that device.

Tagging and commenting because I’ll interested as well. I haven’t tried this, but I’m curious about others experience with it.

Fwiw, I’m mostly an Aeropress user - mostly because I prefer the flavor, but partially because it works perfectly well with metal filters…

I have one just like this but larger and made to close entirely for coldbrew.

I have one, it’s okay if you’re super diligent at keeping it clean and washing it out right after use.

I never use it anymore because the paper filters are more convenient.

I’m currently using a pair of them for pour-over in a Hario V60. As others have mentioned, they do taste differently than paper filters. I rinse them thoroughly after each use, then hang just inside a sunny window to dry quickly. I also alternate each day between the two that I have, so that each one has an extra day to stay dry. Doing this while boiling them once a month or so keeps them well cleaned, no odors or odd tastes. However, you do end up using a decent amount of water over time to keep them clean; it’s unclear if saving a year’s worth (how long two CoffeeSocks last according to the manufacturer) of paper filters is worth the extra water consumption. I’m thinking of switching to paper myself, and keeping these as a backup.

Holds too many old bad odors and oils. Use a metal screen filter or Viet Phin or French Press or moka pot if you want avoid paper filters

I used to use a reusable gold filter and it worked fine, but the main issue was having to rinse it out every time.

I imagine these would be similar, but harder to rinse because they’re non-rigid.

I’ve used a larger version for cold brew in the past and it worked well. It was a bit annoying to clean out but cold brew batches arent every morning so it was fine.

My preference is now an aeropress with a fabric filter. I use this above a metal filter with the Prismo attachment (metal to stop the fabric clogging the valve). The fabric circle is small enough to be easy to clean, freeze and thaw. I usually only rinse it (much easier with a small flat disk) before chucking it in the freezer but I use Cafitza to clean it every few months to remove any built up oils (just gotta give it a few soaks in boiling water afterwards to ensure its not holding on to the cleaning agent!).

Some things are better left single use. Hot water pour over to clean the filter then add the grind.

I don’t have experience with the coffeesock, but I have use the Hario Woodneck filters daily. My method is this: boil water, run hot water through filter, add grinds, then do normal pourover method (may want to adjust grind since it may drain faster). After brewing, dump grinds in compost, rinse filter, put filter in small jar. Pour leftover boiling water from kettle into jar. Store in the fridge until tomorrow. Periodically (preferably monthly), you should clean the filter by soaking it in a combination of water and a little Cafiza. You have to really rinse well after the soak, because you really don’t want to taste that in your coffee. I have never used a Moccamaster, but I don’t see why this filter wouldn’t work for that since it takes V60 filters.

This process is basically what Hoffman recommends. I personally prefer my coffee through this filter since I like the oils of the coffee, but don’t really want the fines passing through the filter. That said, it does get very tedious sometimes; I have a metal filter that I use when I’m too lazy to go through this whole process. They aren’t really much of a cost-saving or waste-reducing measure. It takes quite a few pourovers before you save money (though I dunno, maybe you buy really fancy filters) and paper coffee filters are compostable. The most cost-effective solution really is a metal filter. However I think the fabric filters produce the best coffee IMO, but I’d imagine people who prefer lighter roasts might actually prefer the paper filters.

I’ve had this but larger for making batches of cold brew. Loved it, but like someone else mentioned, cleaning it and rinsing it out was slightly annoying.

So my issue with this is the amount of water you need to use to clean it. Paper is compostable and bio-degradable.

I conceptually like them but I honestly find maintaining them too much work… If you can remember the frequent boilings they need, they make excellent coffee
