Filtron Cold Water Coffee Brewer review: Brews cold coffee but uses more parts

The Good The Filtron Cold Water Coffee Brewer offers an affordable way to make cold brew coffee at home. The cold brew the Filtron makes is rich and delicious, and you can use either disposable or replaceable filters with it.

The Bad The Filtron Cold Water Coffee Brewer is more complicated to use than other cold brewers thanks to its multi-chamber filter.

The Bottom Line If you don't mind a little extra set-up hassle and you want the flexibility to use different filters, the Filtron Cold Water Coffee Brewer will serve as an affordable gadget for making quality cold brew coffee at home.

Able to make large amounts of tasty cold brewed coffee at a time, the $40 Filtron Cold Water Coffee Brewer doesn't demand much of an up front investment either (the price roughly converts to £30 in the UK and AU$55 in Australia). The manual contraption is a bit tricky to operate though due to its big size and more parts than its competitors.

Similar to other cool water brewers such as the Toddy and Oxo systems, the Filtron is essentially a plastic, cylindrical bucket (called the "coffee bowl") that holds coffee grounds and water for steeping, which you then place on top of a container for decanting. Like those other products, you also must plug a tiny hole on the bottom of the coffee bowl with a rubber stopper.

The Filtron cold coffee brewer is tall, large and unwieldy.

Where the Filtron differs though is its use of a second "water bowl" designed to trickle brewing liquid over its supply of coffee grounds. The water bowl has no stopper for its small bottom opening so your finger is required. That's three main sections in all, two of which you perch rather precariously on top of a very slender plastic carafe. Perhaps that's why the vessel is plastic as opposed to fragile glass which the Oxo and Toddy products use. It feels as if one stray nudge could tip over the entire set up.
