Do you have a standard size stainless steel filter for your Aeropress (Coava or Able Brewing) and are curious about how it compares to the fine size? Here are some pictures to illustrate the differences:
The standard filter is fairly rigid with larger holes. To avoid sediment in your coffee and clogging the filter holes, you should grind to a medium grind. The standard filter is durable to withstand a fair amount of abuse.
The fine filter is very thin and flexible. While it allows you to brew with a medium-fine grind without clogging the filter holes, it does mean that you need to be careful when pressing not to exert too much pressure. Too much pressure can warp or damage your filter.
There is a significant difference in the number of filter holes per end cap hole, as evidenced in the images below.
So, is one better than the other? The simple answer is, “no.”
The durability of the standard filter makes it a better choice when travelling or camping, but the fineness of the fine filter makes it a great option for brewing with the inverted method.
Both styles have strengths and weaknesses — choose the filter that best fits your preferred style of coffee, or keep both on hand to give yourself more options.
