Reusable Premium Metal for Use in the AeroPress Coffee Maker, Package of 2

After pouring too much water into aeropress to make first coffee, realized that filter screen allows water to fill up cup. With paper filters, no water passed through. Filling press up half way does not overfill cup. Now less mess and coffee still tastes great.

What's more to say, it works great, filters a bit quicker than paper but not so much that it makes much difference; and so far a quick rinse under that tap is all that's needed to clean it.

Funciona bien para técnica invertida

I've been using the Aero Press for about a year with the paper filters it came with. Now that they are almost gone, I decided to buy a reusable filter. I read many reviews and based on them two of the best filters seemed to be the Slimm Filter and the Coffee Nebula. I decided to buy both and do a side by side comparison. They are very different but both earn a 5 star rating from me. Hopefully I can articulate the differences for the buyer so they can make an informed decision. First, a word about how I make coffee and why, which has a relevance to the first point of differentiation, coffee sludge at the bottom of the mug. I heard the inventor of the Aero Press give a talk about making coffee. Basically, as long as you have clean equipment and water, the next most crucial thing is the temperature of the water. He said above 175F, more of the bitter oils are released from the grind making a more bitter morning brew. Keeping the water between 165-175 makes wonderful coffee overtime, but needs to be microwaved to bring it back to a nice hot drinking temperature. This is why I press into a ceramic mug to microwave, then transfer to a stainless steel travel mug, leaving the sludge behind. So for me the sludge isn't really an issue. For those where it is, the Slimm filter lets through 1/3 to 1/2 the sludge that the Coffee Nebula filter does. All reusable filters let some through compared to paper, but the Slimm is pretty close to paper. Cleanup. They both only take a few seconds to clean, rinsing them under the faucet. But since the Coffee Nebula is smooth, it is slightly easier. But it takes more effort to scrape the grounds of filter of both. So, not a big difference between them, a non-issue. Construction: The Coffee Nebula is constructed of a single piece of stainless steel with holes drilled into it. The thing is virtually indestructible. The Slimm Filter appears to be well made. The rim is about the same thickness as the Nebula. It is constructed of two pieces of stainless steel with the ultra fine wire mesh spot welded between them. This may seem weaker, but since it's lying flat on the plastic mesh bottom of the Aero Press, unless you have grinds or something else under the filter, it should be fine. Seepage rate. The Slimm filter rate is almost the same as paper. So if you have your grind size calibrated for the desired amount of steeping with paper, this is a direct replacement without adjusting your grind. The Coffee Nebula on the other hand has lets the water through at 1/3-1/4 the rate and will require more pressing. I usually calibrate the grind so that I just let the water slowly seep through while I'm making breakfast so I just have to press the last 10-20%. With the Nebula, I'll have to go to a finer grind which will also let more sludge through. On the other hand, my coffee is a little stronger without using more grounds. Leakage. In a lot of the reviews people complain about leakage, even with the paper. I have never had any leakage period, with either filter or with paper. I suspect they have a defect in the mating surfaces of their Aero Press, it's dirty or they are not screwing on the bottom of the press hard enough. It should not be leaking. Final note, both filters are great, hopefully now you have enough information to decide which is right for you.

Looks good. No complains here - fits well, filters well. Does what it is supposed to.
