15. Snopes did a good break down of this argument

What's True
Breathing in excessive carbon dioxide is dangerous for the body. Some people with preexisting respiratory illnesses may face health issues only with prolonged use of tight-fitting masks, such as respirators.
What's False
However, people wearing cloth or surgical masks are in little to no danger of breathing in unhealthy amounts of carbon dioxide.

Ultimately, the impact of a mask on its wearer depends on the wearer’s health, any pre-existing respiratory illnesses, the type of mask, and the length of time the person wears it. In most instances, the effects of prolonged cloth mask usage are small. Masks, like most short-term measures to prevent the spread of COVID-19, should be worn only if the wearer has to be in close proximity to others, and be used in addition to necessary measures like social distancing, and more. As such, we rate this claim about the dangers of masks as “Mostly false.”

And also ask them to research herd immunity in Sweden is failing and per capita they have high infection and death rates. But if your conservative family members insists he is correct then he really shouldn’t be forced to wear a mask and face the consequences.
