Newbie looking for help - Respirator for fiber glass

Hi there first time post, but excited to be joining a talented community :)

I was wondering if any one could guide me on the best/proper respirator mask or cartridges for working with fiber glass/ and epoxies?

I currently have this mask

NEW 2 PC PROTECTIVE DUST FACE MASK RESPIRATOR & GOGGLES SET TWIN GAS CARTRIDGE | eBay

Which uses rc 203 gas cartridges, which I use for sanding/spray painting, but was unsure of it's suitability for fiber glass, and didnt want to start practicing/ learning fiber glass without proper safety.
