Saw Passenger X sitting in the gate house wearing a mesh mask. I pointed it out to the gate agent and he stated it's approved; because it covers her nose and mouth. But I stated; no; because it's see through and mesh. Masks have to be made of solid material.So thinking the gate agent would say something to her about the mask Passenger X boards the plane and takes her seat wearing her mesh mask. FWD Flight Attendant (FA) sees this and questions it and then calls me for a reference. I stated to her; I don't think it's an approved mask for flying; let me find it in the manual before going to Passenger X. While I'm trying to find it; FWD FA sends a message to the gate agent about Passenger X wearing this mesh mask.  FWD FA also informs the Captain as well. After searching under COVID section; I find it and inform FWD FA and the Captain that it's not approved and that I'll inform her that her mask is not compliant. I approach Passenger X about her mesh mask and also show her in manual that it's not compliant. Passenger X makes a statement that she's been allowed to wear it on her flights. I then read the mask compliance portion in the manual verbatim. She makes a little fuss about it and then states 'Fine; hand me a mask.' I tell her 'Thank you.' I head back up to the FWD part of the cabin; galley area to inform FWD FA and Captain we're good. Passenger X switched out her mask for one of our mask. Also show them both in the manual where it's located if there's ever any other issues that arise in the future. They can both reference. Also state to the gate agent that Passenger X mask is not approved.
Flight Attendant reported a passenger was required to remove a mesh face mask; while the Gate Agent did not agree; and use a company supplied mask before departure.
