This is a great example of a “micro optimization.” It feels good but ultimately does jack shit to help you.

There are studies suggesting adding paper filters to coffee increases bad cholesterol, and cardiovascular disease kills more people than cancer every year. Whoops? Brussel sprouts ever so slightly elevate your chances of getting cancer. Anything with an ethyl in it does too.

All of this to say, pick better risks to worry about. Everything is a tradeoff. Better chance you die in a freak car accident rather than developing cancer from drinking coffee that was filtered without paper. It is not worth the fuss.
