in my opinion, the filter papers impart very little if any taste themselves. my test was blind-tasting between water that had been passed through a paper filter vs not.
in my opinion, the paper filters do improve the coffee a lot vs other non-filtered methods because they capture fines and oils (which dont taste great themselves).
in my opinion, reusable cloth filters seem like a nightmare to maintain. the fine reusable metal filters do work but they don't capture the oils.
