Works well but too much work for me
10/31/2019 by Krissy
This is a fine product and works like it says it will, just makes too much mess for me. Have to wash and clean filter and one/two bottles every time. Which can be time consumming when minutes are precious in the early morning rush to get to work.
Won’t Fit Any Mason Jar I Buy
07/19/2019 by Lauren
I’ve bought three jars so far and the lid fits none.
What am I doing wrong???
07/08/2019 by Laura
I can’t get it to work right. The water just will not drain through the coffee after the first inch or so when I flip it. I keep shaking it to only get a few drops per minute. I left it on the counter to “ do its own thing” and the coffee never drained through the filter. My coffee is standard drip grind... not fine expression grind. I be tried it 3 times. Waste of money.
Works as advertised

Easy To Use

This filter is easy to use with standard canning jars to create delicious cold-brewed coffee. The price is very reasonable.

Cold Brew Mason Jar Filter

Transform your mason jars into a cold brew maker and enjoy the smoother, more flavorful, less acidic taste. This filter fits right over the wide mouths of two mason jars to sieve out the coffee grounds.


Make your very own cold brew coffee, easily. Put this cold brew coffee maker filter onto a wide-mouth mason jar.

It’s super straightforward. Let coffee grounds soak in a cold-water-filled mason jar for over twelve hours. When you’re ready to get your caffeine dose, twist the filter onto that jar with the straw side down. Then twist the second mason jar on top of the filter. Flip. Shake. And watch your cold brew filter through.

In case you’re uninitiated to cold brew, it’s smoother, less acidic, and it’s easier on your tummy (and teeth, too) than coffee brewed with heat. Less acidity also means you can better taste all the subtle flavors—like traces of chocolate, fruit, and nut inherent in different beans.

And even though grown-ups are the ones most likely to enjoy their coffee, this filter was invented by a teen. Max Feber was just 16 when he came up with the idea. It’s one you’ll be able to enjoy every day. more Their Story
