This. How does one tell whether this affects a particular brand or not?

The article says that it is the "silken" pyramid shaped tea bags that are made of plastic.

I buy tea loose-leaf at the asian grocery store and steep it in a glass coffee press to filter out the leaves. Yay super cheap and no microplastics!

If I understand correctly you can easily spot those types of bags. Instead of paper they look like a fine plastic mesh. Lipton uses them in their pyramid-shaped sachets.
