Like most respirator masks and military gas masks, this mask has an unfiltered exhalation valve. This is a one way "flutter" valve. It lets air out when you exhale, but it is sucked closed when you inhale. If it didn't work this way you would suffocate on your own CO2. This mask does accept 3m "bayonet" fitting filters and cartridges.

Question about how gas masks work : gasmasks

Anything with an exhale valve will not filter the air you breath out, only the air you breathe in. IMHO a full face gas mask is overkill for viral protection. Especially with combined filters (with activated charcoal). A half face respirator, either reusable or disposable, will do just fine.
