@annika This is what my partner and I use for travel. Expensive as all hell, but I have multiple immunocompromised family members so we’re cautious. https://cleanspacetechnology.com/cleanspace-halo/
You can talk through the clear half-mask and it has replaceable inbound/outbound filter elements that protect you and those around you. It’s a positive-pressure respirator w/breath-responsive motor that keeps the air fresh and cool. Always happy to share more details than would fit in this one toot!
