I have a bag of 10 Rombouts filter coffee cups and I wonder if these can be reused:

I wanted to reuse them but have concern from health perspective as well as practicality of this. Since coffee in a used filter cup has been used, I would remove it and place coffee pod in its place.


  • +1 for the picture.

If you can remove the coffee grounds/filter and replace just those, then yes it will be safe from a health perspective. The plastic in the filter "cone" should be food safe, though durability may be an eventual concern. The plastic cup base can definitely be reused, as is intended.

As far as the practicality concerns go, it may be more of a pain than it's worth. The coffee containing part of the filter funnel is going to be pretty well attached, in order to keep it from slipping into the cup below and steeping (like tea) vs. simply having the water run through it. You could probably remove the coffee filter and perch a coffee pod in it's place, but it would not be sealed to the plastic cone, and hot water may run around it without actually percolating through the coffee grounds in the pod.

  • Since I love DIY I also had another idea. Maybe it is even less practical but what would be your opinion on removing original used coffee filter in this cup, leaving only plastic frame and placing a layer or two of kitchen paper towel inside?

  • Another question. Does Robusta have higher caffeine content than Arabica? Is instant coffee as we know it just a caffeine content concentrated Robusta which "hits stronger" than Arabica? I sometimes drink coffee at 4PM and my intent is to keep it as low in caffeine content as possible.
