The silky pyramid bags are the worst. Paper bags should be ok, unfortunately a lot of bags that appear to be paper might not be, or might be mostly paper with some plastic threads holding it all together. Almost impossible to tell just by looking at it.
Stick to old fashioned paper tea bags and you are fine. Don’t use those pyramid shaped silky ones.

Just get a small teapot and don’t worry about it. Loose leaf tea isn’t any more expensive and allows you to control how strong you are making things.
