The Filtron is an easy to use brewer that will change your perception of cold brew coffee. 

It uses two filters where the typical cold brewer only uses one, has a wool filter as well as a paper filter which creates one of the best cups of cold brew around.

It’s also quick and easy to set up a brew.

With the water bowl attachment on the top, you can quickly pour your water into it while it is slowly distributed over the coffee grounds.

Things to Consider Before Buying a Cold Brew Coffee Maker

It’s pretty awesome to be able to make cold brew at home.

It’s so convenient to have some sitting in the fridge when you need that afternoon pick me up but don’t want to drive down to the coffee shop and spend $5.

The cold brew process naturally produces a cup with less acid. It’s smoother and easier on the stomach if you are one of many who are sensitive to the acid present in coffee.

With a brewer like the Filtron, a coffee concentrate is produced.

The concentrate needs to be diluted before drinking.

What’s cool is that you can either dilute the concentrate with boiling water, for a smooth cup of hot coffee, or with ice water for a refreshing cup of iced coffee. 

Another important factor to consider: is it easy enough for someone like me to use? I don’t want a science project. 

How long does it take to start the brew? Is there a lot of cleaning involved once I’m finished brewing? 

Does it make a lot of coffee?

If i’m going to take the time to make a batch of cold brew, I want it to last at least a week, if not more.

Let’s see if the FIltron has what it takes to be your brewer of choice.

The Filtron Cold Water Coffee Concentrate Brewer Review

It also has a water bowl, set on top of the brewer for the best distribution of water over the grounds.

The rest of the brewer is very similar to the Toddy Cold Brew Coffee Maker. 

The Filtron will produce a good amount of coffee concentrate.

One batch will last a week for an average coffee drinker. The concentrate itself can stay in the fridge up to 2 weeks. 

The price of the brewer is comparable to the Toddy - not the cheapest, but definitely not the most expensive brewer.


  • Wool and paper filter for maximum filtration.
  • Quality of coffee is excellent.
  • Easy to use and easy to clean up.


  • Wool filters need to be cared for between uses and replaced every 2-3 months. You will also need to purchase paper filters over time.
  • Very similar design to the Toddy, not very original.

Watch this video to see just how easy it is to use the Filtron:

The addition of a paper filter along with the wool filter is what sets this brewer apart. That added filtration gives the Filtron a slight edge over other brewers.

The final cup is very balanced, very smooth and very enjoyable.

The wool filter takes care of most of the filtration. Between uses, it needs to be washed and refrigerated. It’s good for about 2-3 months before needing to be replaced.

They aren’t very expensive, though.

The paper filter is the icing on the cake. It ensures a sediment free cup and softens the acidity even more.

The Water Bowl

The other aspect of the Filtron that sets itself apart from the Toddy is the water bowl.

With the Toddy, you need to add a little bit of coffee, followed by a little bit of water, then coffee, then water, etc.

This is to ensure even distribution of water. It also keeps the filter from getting clogged.

With the Filtron, however, once the ground coffee is in the brewer, you don’t pour the water directly over top. You placed the water bowl on top of the brewer and pour the water into the bowl.

This bowl will let the water drip very slowly into the coffee grounds.

This makes it much easier to use than the Toddy. Simply pour the water into the bowl and walk away.

Alternatives to Filtron Cold Brew

Okay, okay, the Filtron might not be for everyone.

If you don’t like the idea of replacing the filters every once in awhile or think there are too many pieces involved, we’ve got some other recommendations for you. 

Hario Mizudashi

Hario Mizudashi

The Hario Mizudashi Cold Brew Coffee Pot is a great cold brewer for many people. It’s minimal design makes setup and cleanup as easy as it can possibly be.

The brewer has only 3 pieces; the carafe, the permanent mesh filter and a lid.

Simply add coffee grounds, pour water over top and let it sit for enough time to give you either concentrated or low acid coffee. Once finished, just remove the filter basket and you’re good to go. We reviewed the Hario cold brewer in detail in this post.

Yama Cold Drip Tower

If so, this is probably the brewer for you. The Yama Cold Drip Maker is the ultimate cold brewer for coffee nerds.

It comes with a high price tag, but the aesthetic alone might be worth it.

Bring the beauty of this glassware into your kitchen and your friends will think you are a chemistry wizard.

It makes excellent coffee if you are willing to adjust different variables to your liking.

French Press Cold Brew

Looking for the easiest and cheapest way of brewing cold brew at home?

Simply use your french press. You probably already have one at home.

It’s a super easy process that’s great for beginners. Just be aware that the french press filter isn’t designed to produce awesome cold brew.

It works, but having a dedicated cold brewer makes a big difference.

The Verdict

It’s hard to beat Filtron cold brew.

With a high quality results and ease of use, more people should consider this brewer to solve their cold brew needs at home.

The wool and paper filter combination and the water bowl that slowly distributes the water make this brewer one of a kind, even though it looks just like another brewer.
