Correct me if im wrong.

We keep trying, but you don't listen.

CO2 is not needed and some diving systems actively scrub it out.

Yes, but you don't "consume" it like you consume oxygen. It's a waste product, not a vital gas. Besides, following your logic, shouldn't the face mask increase carbon dioxide consumption instead of decreasing it?

i believe both O2 and CO2 are essential particles that are being inhaled during normal respiration.

Correct me if im wrong.

Oxygen and carbon dioxide are not particles.

From "Facemasks in the COVID-19 era: A health hypothesis":

Why are you quoting a False News article that contains a great deal of misinformation.

You seem to be trying to pass off incorrect info by wrapping it up in pseudoscientific language.
Calling yourself ‘smart’ rather than ‘tdkm30’ doesn’t make you smart.

This is another piece of misdirection:

Did you ever attempted to hold your breath while underwater? Chronic/intermittent mask wearing does alter systemic oxygen and CO2 input in such ways that your brain cannot notice any differences. This is known as hypobaric hypoxia and its well-known scientific phenomenon.

Hypobaric hypoxia (also known as altitude sickness) is a result of lower air pressure, not the increased pressure experienced during swimming underwater. It is not an effect of mask wearing.

Long time no see eh?

Thank you for posting this. I had actually been fooled into thinking it was legitimate.

3. Myth: Wearing a mask will increase the amount of carbon dioxide I breathe and will make me sick.

Fact check: Breathing through a face respirator or surgical mask will decrease oxygen and carbon dioxide consumption.

Note that this is out of scope from the original thread.

No surgical masks will not reduce anything because they are open and designed for surgery specifically to prevent droplets or breath from a surgeon entering into the area being operated on.

So you are referencing m95 masks used in the building industry to prevent dust respiration. Most people that are forced to wear these masks at work are also advised about how long for, how much time they need to take a break without the mask. As for the general public, most people only use a mask while shopping or on public transportation, which seriously limits the amount of time people wear them, at a school I attended people only wore masks while moving arround and took them off when safely social distanced at their desks.  There is no need to wear a mask outside.
Ergo I doubt the effects you are concerned about would actually happen, people are not wearing masks all day everywhere, and shouldn't at worse they intermittently wear them for a few hours max.

OK
You should be able to tell us where to find that "advice" if it exists.

Please do so.
Otherwise it just looks like you are making  **** up.

As far as I am aware only WHO make any comment about length of time a mask should be worn (4hrs) but nothing about breaks, I think Australia and France follow that.
CDC and HSE don’t give any limits, quoting wearer times of up to 8hrs in studies. They do mention that some people may suffer heat rash or dermatitis through prolonged use, but leave it to individuals to decide.
The WHO recommendation seems to be based on a worst case of hot humid conditions and the time taken before the mask becomes uncomfortable and wearer starts adjusting it.
In reality, the need to eat or drink, or just take a break are likely to be the limiting factors.
