Use this filter system to make delicious cold brewed coffee and steep loose leaf tea for the perfect, smooth beverage any time of year!  Coffee and tea made through this system is good for you and the environment.  Did you know that cold brewed coffee has a lower acidity level, which is good for your teeth and your stomach.  Because it’s never been heated, the chemistry isn’t changed, you can save it in your fridge for a week or two and the taste is never altered.

Cold brewed tea is also lower in tannins and therefore provides a smoother drink.  Loose leaf tea is better for the environment because it uses fewer resources by skipping the bag and tag.  You can compost your leftover grounds and tea leaves for a richer garden.

This system includes:

  • Two different silicone seals in order to make it leak proof.  Use only one at a time.
  • Stainless steel filter
  • Stainless steel lid


For brewing and steeping:

  • Only use the “wrap around” silicone seal that seals both sides of the metal filter (against glass and lid). This seal is optional if you keep the jar upright.
  • Cold Brew Coffee – To make cold brew coffee concentrate, fill the filter tube about 3/4 full with coarse ground coffee, to allow for swelling.  Pour in cold water to fill jar and allow it sit on your counter or in your fridge for 24 hours.
  • Loose Leaf Tea – To steep loose leaf tea, combine 1-2 teaspoons of your favorite tea with 6-8 oz of cold water and place in fridge.  Steep white or green tea for 6 to 8 hours; steep black or oolong tea for 8 to 12 hours depending on desired strength.
  • Hot Coffee or Tea – You can also use this filter to make hot coffee and tea. Put the grounds or leaves in the filter, pour in 200 degree water, and wait a few minutes.
  • Once brewing/steeping is complete, remove the filter, dump grounds/leaves into your compost, pour over ice, add your favorite coffee/tea additions and enjoy!

For storing: 

  • Keep your brewed coffee and tea in your Mason jar fresh and leak proof with the other silicone seal and stainless steel lid included.

Helpful tips:

  • Be sure you use coarse ground coffee!  A higher quality coffee grinder will give you a more consistent coarse grind. Cheaper grinders produce a mix of coarse all the way down to powdery grinds. This filter is very fine, but silty coffee grounds can get through.
  • The cold brew coffee concentrate will be strong, so you may need to dilute it. Serve it hot or over ice, add sugar or dairy, or any other way you like!
  • To make a more concentrated version, use more coffee grounds or steep for longer. Cold brew coffee is commonly made very strong and diluted at serving time.
  • If your filter is already in use, you can put your coffee grounds or tea directly into the jar. Once your filter is available, pour the contents through the filter into a new jar.
  • They are 10cm, 15cm, and 21cm tall. The mesh part is 7cm in diameter. The mesh is 100 micron dutch weave (some competitors call this 80 micron). Quart are now upgraded to 50 micron.
  • All parts are dishwasher safe, and I find this the easiest way to clean them.

Easiest way to make Cold Brew

When I made cold brew before it was a huge mess and took so much time to get the coffee grounds and concentrate separated but now it’s so much easier and there are no left over coffee grounds in the liquid which was an issue for me before! I love this thing! The only complaint I might have is with cleaning it I get scared I’m going to bend it. But it’s very sturdy, I’m just a worrier. Lol

No complaints 👌

I love this filter. I used it to make iced tea in a 1/2 gallon mason jar. This one is my second and better than the very old one because it comes with a nice jar cover and seals.
Believe it or not my husband took the old one to use with his pump sprayer for yard use. G

Brewing method still best so far, 3 years later!

My oldest of the two quart set versions was ordered August 2019. I've used both all the time, since then. No denting, but I'm careful how they are cleaned, and where I place them in the dishwasher. They arrived un-dented. Both have required soaking in an enzyme cleaner/strong degreaser type dishwashing liquid for tiny coffee bean particles. So it helps having two, while one is getting a better cleaning. I also lost one of the gaskets. It's probably in the compost or in one of the garden beds, but hasn't surfaced, so I've been checking for stock on those replacements. Thinking of getting the half gallon, because that is how I've been using the quart versions anyway, and the grounds space in those filter is tight. I do still have to pour the coffee through a muslin after brewing before storage in 2 quart jars, but it runs through much faster than any previously used method. Muslin sits over a canning funnel, so it's not like I need to babysit it the whole time. It's fantastic waking up to no electric, yet knowing I've still got fresh coffee coming and finished, no electric required. For however long it takes them to get electric service working again. (Just have to keep a few batches of ground up beans available.) Love these, wouldn't want to be without them!

Very happy!

I'm so happy I could use the Mason jars that I already own and didn't have to buy anything else. Easy to use and clean.
