The coffee is compared to paper filter through with the S-filter full-bodied, as more coffee oils. Not quite as powerful as the Able-filters, but significantly less coffee residue in the empty cup. The taste to me like the result also better than with the Able-filters at least, if you like me like something lighter roasted coffee beans are preferred.
I have then ordered the current version of the S-filter here on Amazon of pure interest. Again more workable than the first version. The taste I imagine there firmly but little difference.
Conclusion:
So far only used paper filter? S-filter is worth it!
To date, only paper and Able filter used? S-filter is worth it!
Already in possession of the first version of the S-filter? Upgrade to the newer version here does not have to be.
