Honestly, for people in a high-risk category, especially those suffering with upper respiratory diseases such as COPD, etc., wearing a filtration system like this would probably be a good idea.
I imagine trying to talk with one of these on would make you sound like Darth Vadar.

..this is like being trapped in a room full of science nerds...help...
I thought Dodger's CO claim was BS but it contains some truth.
Old style gas masks use activated carbon. Soot in exhaust gas would similarly absorb CO that can be released in the lungs.
This is why the quoted article talks about "EXPIRED" CO.
Sorry for doubting you Dodger :-(

(Correction: N2 should read N3)
That report is measuring EXPIRED CO.
We are discussing INHALED CO, which is not the same thing.
The also don't give enough detail to establish if the experiment method is robust or offer any theoretical explanation for the expired CO change measured.

My level of pessimism increases with my age and so I have painfully replicated Dodger's nightmare. Frequently. Others too; but I'll save those for another occasion.
Also don't forget to remove your mask before eating:
