Yes, I still think that the filter might be part of the con.
If there is a filter, in there, the bad stuff will be trapped in there, and will grow, steadily, for all the time until the filter is changed.
But if there is no filter, the effect on the taste buds would only be the stuff collected during that boil session?
Well of course there is also the very usual situation where companies feel the need to cover their backs for all eventualities, even if highly unlikely.
