The Not So Good
Made from stainless steel
Tighter fit, need to press harder
Fine mesh keeps "coffee mud" out
Easy to clean
A Warren River Goods reusable stainless steel filter is a great way to "green" your morning cup of coffee. The filter is made from 100% stainless steel with the mesh inside and a metal rim. The filter is pretty thin and fits right into the main chamber of the Aeropress coffee press.
Usage: The stainless steel filter is used in the same way as the paper filter. You place it inside the Aeropress chamber, add the coffee grounds and then the water. And, press the coffee through.
The paper filters will absorb some of the delicious and healthy oils in coffee, so you lose out on flavor. The stainless steel filter lets those oils through! We decided to do a little experiment. We used a scale to ensure the same amount of coffee and water. The first cup was pressed with the paper filter. The second cup was pressed with the stainless steel filter. Results - we could taste the difference. The second cup had slightly better taste and fuller body. I really like that the stainless steel filter lets through the oils that paper filters absorb.
A paper filter is more fine than a stainless steel filter. One thing to consider is that the stainless steel filter is going to let water through a lot faster. The hot water is in contact with the coffee for less time and could extract less flavor or different flavor than when using a paper filter. This could change the taste of the final cup of coffee.
Results: The stainless steel filter does not result in the "paper" taste when making a cup of coffee. I was worried that the stainless steel filter would "muddy" the coffee a bit (like a French Press usually does), but I did not notice any difference. The stainless steel filter mesh is fine enough to keep even finely ground coffee out of my cup.
The stainless steel filter is thicker than the paper filter, so the fit inside the Aeropress is tighter. I did have to apply a little bit more pressure to get the coffee through, but this is something that I would get used to after a few uses.
The filter is easy and quick to clean. I used a dish brush with a little bit of natural soap on it and brushed it over. The stainless steel filter also dried quickly.
If you are looking for a reusable stainless steel filter for your Aeropress, I would recommend the Warren River Goods filter. At around $15, it is an investment up from, but I can see the filter lasting for lots of years and eliminating the need to continue spending money on disposable filters. The filter does carry a lifetime guarantee, though I am not sure with daily use that it would last that long. My husband still prefers the ease of disposable filters at work and I prefer the use of the reusable coffee filter at home.
