Question

Why is indoor smoking banned in many places especially in ac rooms?In science?

Answer 1

Cigarette smoke contains gaseous pollutants, which are small enough to be inhaled and stick to your lungs. Some of these harmful chemicals include carbon monoxide, ammonia, arsenic, benzene, and hydrogen cyanide.

While air conditioners have filters designed to improve indoor air quality, the amount of pollutants released by a cigarette is so substantial, it rapidly coats an AC filter with residue. Filters need to be changed at least once a month.

Hope it helps☺
