The Aeropress Metal Filter: Does It Save Money?

The Aeropress has always been a favorite around here, but its reliance on disposable paper filters requires owners to stock up on replacements. A company called Able has come to the rescue with a reusable metal Aeropress filter. Its DISK filter promises to settle your filter worries for good, but how does it stack up cost-wise against the cost of paper filters? Can it save money?

Whereas paper filters are cheap up-front, the DISK coffee filter is a more significant investment. The price for for 350 AeroPress micro filters is $5.02 on as of this writing. The DISK filter is $16.99— half the price of a brand new AeroPress. I’m using Amazon prices for this comparison because they are generally very competitive and there’s no need to factor in the cost of shipping. This analysis also ignores differences in taste preference.

How many paper filters would you have to go through before you started saving money? According to my calculations, nearly 1185 ((16.99/5.02)*350). Assuming you go through one paper filter a day, it would take 3.25 years before the DISK filter paid for itself. Keep in mind you can rinse off the paper filters between brews and use them again, but I wouldn’t let a used filter sit more than a few hours.

Is the DISK coffee filter a money-saving investment in the end? I’ll leave that decision up to you. The steel construction of the filter should easily endure 3 years of use, but it’s easy to lose or accidentally damage such small things over time as well. If you only use the AeroPress occasionally, it’s most likely a money-losing endeavor. Heavy AeroPressers will likely find the filter a good buy, though.


  1. Besides the cost-argument…try it somewhere and let the taste-experience blow you away…I mean…seriously…it’s awesome…

  2. Why do you focus on price when quality and results count more? Suppose you wouldnt cover half the items listed on this blog if that was the case.

      Freddy, at CoffeeKrave we focus on both price and quality. The vast majority of coffee drinkers have commitments such as children, mortgage payments and professional development, however. Because of this I try to focus on products that provide great quality but are still affordable– good coffee does not have to be expensive. I plan on testing the DISK filter in the future and have no doubts that it produces better coffee with the AeroPress. This post simply examines the cost factor, a topic no other blog has covered until now.

  3. “..but I wouldn’t let a used filter sit more than a few hours.”

    I always reuse my paper filters, and I’ve never had a problem. Just pop it back into place after you’ve rinsed everything out. The filter I have on it now has been going strong since the beginning of the month.

  4. Paper absorbs coffee oils while a metal filter does not. It is the core difference between filtered coffee and French Press. If you use good coffee letting the oils through enhances the flavour. If you use inferior beans removing the oil mellows the bitterness.

    I greatly, greatly appreciate that this blog actually considers price! I am a college student with limited funds, therefore I am so happy to have stumbled upon this great place! I am a coffee lover and I noticed I spent 150 dollars on coffee this semester already! It is ridiculous and it has not even been more than 30 coffees mind you. I am tired of my usual expensive frappuccinos with espresso shots-too much sugar and not enough coffee. I’ve begun to love those nutty vanilla flavors that are 2 bucks for a small cup that has unlimited refills at the coffee shop inside my library. But I notice I get too busy to even go for more! I want a coffee maker that I don’t need to add hot water to (because my dorm has community bathrooms and thus no personal sinks) but that still makes great, warm coffee! :( I also want to be able to use my plethora of water bottles. Oh also, any tips to avoid getting burned by your coffee? I always have to wait until it cools down considerably LOL!

      Try an Aeropress! When I lived in a dorm I walked down the hall to fill up my electric kettle in the community kitchen for heating in my room. The Aeropress has a lower brew temperature than other coffee makers and you’re supposed to add water to it, so the final product shouldn’t be hot enough to burn you.
