I highly recommend these filters for quality and durability. I purchased a set of these filters in August 2o22 and have used *one* filter to brew cold brew coffee once every 10 days or so, and the filter continues to work exceptionally well. (Writing this review in February 2025). The filter shows no signs of wear or deterioration (despite my habit of sqeeeeezing and twisting the filter filled with grounds once I finish a brew, trying to extract all of the wonderful coffee). For cold brew, I use the filter in a one-gallon glass jar that I purchased at Target (described in my next paragraph). I use coarsely ground coffee beans (~160 gm by weight) and ~2100 ml of water, and it yields almost exactly 64 ounces of cold brew coffee. I include photos of my brewing process in action!

The glass jar at Target is called "128oz Glass Jar with Metal Lid – Threshold™: Clear Glass Food Storage Container, Stainless Steel Lid." The price is $6.00

It's super simple, easy to clean and reuse, and makes a nice, crisp, clean cold brew. Definitely prefer it over other methods I've tried. My only thing is the medium size is huge! I make a 2 gallon jug of cold brew at a time using a 1:5 ratio and there was still so much empty pouch leftover that I had to pour 2 or so cups of water out so it would fit. Definitely would recommend a smaller size for anyone making batches for personal consumption.

I've been looking for a while now for a high-quality reusable bag for making cold brew and I've FINALLY found it. I just made my first batch yesterday, and this bag helped to make some of the best cold brew I've made yet. One of my favorite things about it is that cleaning it after using it is SO easy. It cleans up really well and the coffee grounds wash off very easily. Might have to buy some more to make multiple batches at once!

This light weight exquisite fabric filter bag is easy to fill with a cup (or stronger)of coarse ground coffee, pull the drawstring and submerge in carafe with cold water. I used an old glass toddy carafe with a snap on lid. A quart or larger mason jar works too!

Store in refrigerator overnight or longer. Squeeze bag to drain all liquid. I then empty grounds in my front yard flower pots or soil .Rinse bag in cold water till water runs clear and then hang outside to dry. Wonderful! The old toddy systems were cumbersome and cleanup was messy.

I used this to brew my coffee. I love the fact that it’s reusable and that I’m no longer adding to the garbage pile. The coffee tastes great and the bag held up way better than the disposable bags. I just wish the size was a little larger for my brew container.

This bag is a nice size and I like the material. It’s perfect for about a gallon of cold brew. Easy to use and wash. I’m hoping I’ll get many uses out of it!

I used to have a Toddy and was considering getting replacement filters. When I searched filters this doppelganger bag came up, and it has been a joy to use.

I just put the grounds in the bag, added water and soaked for 24 hours and voila excellent cold brew. Simple, easy, fantastic cold brew.

These bags work better than expected, in that they keep grounds out of the cold brew so well I don't need to filter afterwards, and are easier to clean than I would have guessed. Note that this Medium bag is more than enough for a 1-gallon container (in fact, I would avoid the larger bag for this size – all the extra unneccessary fabric might interfere with the cold brew process), and you'll still need something with a nice wide mouth to easily insert and remove this bag full of grounds.
